Zero Emission Blowers for Sulfur Recovery
Canada Blower Co. now offers gas-tight and zero leakage steam-jacketed blowers for Sulfur Recovery in Cemical Industry.
Hydrogen Sulfide H2S is a main source of sulfur. In high concentrations it can be lethal. It occurs in natural gas, oil, volcanic emissions, and some mineral springs. In oil rfining processes its presence is undesirable, and it must be removed. The Clause process is one of the methods used to remove the hydrogene sulphide, and while doing so, recover elementar sulfur.
In pactice this sulfur removal process requires a gas-tight, zero leakage, high temperature and high pressure blower for intermittent duty that must handle toxic gases and must be capable of being brought on line immediately upon demand. To do this the following features on the blower must be provided:
- Double welded casing construction;
- Steam flows between the housing walls to maintain a constant 285 F gas temperature inside the fan (because below 285 F sulfur will change from a gaseous to a solid state and will "freeze" to the blower surfaces causing damage or destruction);
- A mechanical shaft seal with heat tracing and purge by air or nitrogen;
- To assure tight tolerances between the shaft and shaft seal, the housing should be supported at the centerline, and grows concentric to the fan shaft when exposed to heat.: since this support isolates housing from the drive and mounting bases, housing thermal growth doesn't cause forces to be applied to these bases.
- To prevent the shaft from taking a permanent set when the blower is idle but still exposed to the high temperature, a turning gear is provided to keep the blower rotating at a very slow speed of 25 - 40 RPM; alternatively a VFD speed control can be used
Steam jacketed construction can also be used in other thermally critical chemical processes. As to air-tifgt and zero-emission construction, it is used in the following industries:
* Pollution Control
* Pulp and Paper Industry
* Printing and Converting
* Chemical Plants
* Power Generation
* Research and Development
* Petroleum
* Food Processing
* Paint and Ink Industries
for containment of hazardous organic and inorganic compounds in industrial process plants and other critical applications. Special construction and shaft sealing devices are available for blower service requiring zero or minimal gas leakage into and out of casing.
Canada Blower has a lot of experince with gas-tight and zero-leakage construction on fans and blowers, including: multistage lip shaft seals; Buna-N, Viton and Teflon seals; mechanical shaft seals; special fan housing gasketings; single and double carbon ring seals; hermetically sealed blowers; magnetofluidic and ferrofluidic seals; and packed stuffing boxes with barrier liquids and purgeable seals.
Specific code welding processes and special fan design features are used too - to ensure complete gas tight integrity.
Some special materials and alloys frequently used in gas tight fans, especially for service in hazardous, abrasive, corrosive and high temperature environments, include:
Corten, ASTM A36 Carbon Steel, Hastelloy, Inconel, Stainless Steels of different kinds, Titanium, Monel, Aluminum, Teflon, Rubber LIning. These materials are typical for industrial applications requiring high strength alloys and super alloys too.
Canada Blower is a world wide distributor of industrial process ans OEM fans and blowers, as well as fan components; including high pressure blowers, high temperature fans, spark resistant and explosion proof ventilators, tubeaxial and vaneaxial high pressure ventilators. Canada Blower also does existing fans and blowers repairs, re-build, as well as dynamical wheels balancing.

A European Shale Gas Industry It Is Stated That European Service And Goods Suppliers
A European Shale Gas Market
It is stated that European service and products suppliers really should aim into the wind and Solar power development in Europe - however it may be confirmed shale gas development could possibly be far much more exciting for them.This revolution or evolution of the option power development industry is already developing, along with the service and product provider industry is already benefitting from this. Nevertheless, it truly is not too late to participate and to get a share into this big marketplace prospective creating in Europe.
Global Shale Gas Prospective (blue numbers are TCF)
What exactly is happening now is that numerous European countries and main oil businesses have began a entirely different revolution that's about shale gas. The prospective of this power source is tremendous, and nearly untapped at the moment and differ massively from the alternative power industry prospective in many aspects which i will cover here.
Shale Gas inside the U.S.There's an ongoing evolution of the shale gas exploitation within the U.S.. There has been an enormous growth in investment of exploration and production of Shale Gas simply because of two essential technological breakthrough the final decade. The initial revolution was the capability of performing Horizontal Drilling and secondly the development of methodology and technology essential to fractionation the new sort of reservoirs. The gas has traditionally been considered as trapped in porous material like sand or limestones that could create over a lengthy time frame without having an excessive amount of of stimulation. Only through the final two decades the fractionation technology has enabled to extract gas from nearly non-porous reservoirs such as shales and create over a lot more than about 10% recovery of it over several years, it now flows rapidly and in significant quantities into the U.S. market with production levels that now can get over 50% recovery.
Affordable gas to EuropeThis has meant that the prospect of importing LNG (natural liquefied gas) to the U.S. has been significantly scaled down, and most believe that the U.S. is on track to grow to be self-sufficient on gas. That in turn has led to the LNG will likely be redirected to Europe where it's sold cheaply. The whole gas industry is so powerful that even under pressure, Gazprom has had to agree to deliver a number of the gas to Europe at spot costs. Naturally, this creates challenges for classic European gas. A lot of see this only with troubled eyes. But this evolution inside the gas marketplace also indicates enormous opportunities both for existing along with new players.
The oil companies are betting on gasThe technological development has meant that the key oil organizations are now looking at shale gas all through the globe as the fantastic new venue for lucrative energy production. Presence of resources of shale gas is possibly far higher than the present resources of conventional gas. If recovery of gas from these new reservoirs might be high, shale gas could overwhelm the conventional gas in recoverable volumes so that the world's gas resources could be doubled.As a result, the larger International Oil and Gas Firms (IOC's)Â are now racing to secure the rights of shale gas, not merely in the U.S. but also in Europe, China, South Africa and elsewhere. The initial stage we see is acquisition of exploration and development rights of sub-soil resources about Europe and specifically in Poland at the moment in Europe.Shale Gas technologies is new and nonetheless has a significant portion of the learning curve ahead of it. When the IOC's now enter with full force within this region with its technological capabilities and economic powers it is going to create results within the medium to long term perspective, no doubt about this.Much of the impetus is that the IOC's have observed their actions to be limited because of national protectionist resource strategies in numerous oil and gas producing countries. Therefore they've long been looking for new oil and gas opportunities, not least inside the Arctic, the vast seas, and oil sands. Function in these areas will continue, but substantial resources will likely be re-directed to shale gas resources, and therefore away from standard oil ad gas, as long as these classic resources are much less accessible and more tough (read expensive) to locate and generate in existing and new locations.
Peak Oil and Gas ScenarioThe Shale gas Revolution puts a damper on the "Peak Oil and Gas" doctrine, which constantly has devalued the possible of unconventional resources. Gas will now appear as a relatively inexpensive and very plentiful energy source for this century and beyond.This may of course have an impact on the oil and gas industry, especially the gas industry where one effect will likely be that it'll speed up the technologies to convert natural gas into fuel. Gas is for that reason a most welcome option to biofuels, which has been greatly discredited since of threats to food production and also the violent location the have to displace forest and outcomes in greater greenhouse gas emissions. Most specialists now think that it's only the second generation of biofuels based on waste production and sustainable forestry as it really is safe to bet on, along with the supply of these commodities could be severely limited.
Climate Policies and its effect upon renewablesThe focus on renewable energy in each the U.S. and Europe is officially justified in climate policy, but behind this are two other powerful political motivations: The belief that the oil age is ending, and also the require for security of supply. Eg. Al Gore employed both of these elements as page argument when he lately visited Norway.Several think these causes, investment in renewable energy a "No Regrets" strategy in climate policy.There is certainly possibly no imminent end to oil resources, however it doesn't matter anymore, apart from its geopolitical power/conflicts it potentially generates. "Peak Gas" it truly is undoubtedly not in any near future. Additionally towards the untraditional gas resource in shale gas, there are as huge amounts of untraditional gas resources in coal (Coal Bed Methane) - CBM) and hydrates, each onshore and offshore, and shale gas breakthrough makes it most likely that these will eventually be utilized. If necessary it could replace all gas-oil products. Therefore, there is certainly not something left of the negative arguments for the Shale Gas, apart from possible negative environmental impact of Shale Gas and CBM during exploration and production of these resources.
Power Supply SecuritySecurity of supply has undoubtedly been a far far more critical consideration in each the U.S. and Europe - perhaps much more essential than climate. How much of a problem this truly is debatable, but politically it really is a really heavy consideration. Inside the U.S. concern for security of supply is now gone for gas. It will nonetheless final a while for oil, but now it really is far far more fascinating to look in the gas into fuel as a way to solve it.In Europe, the supply of oil isn't a huge concern. Here we're talking about most concerns about disruptions in gas exports from Russia along with a general desire for diversification.Everybody knows that the EU has typically been really concerned about how you can shield energy production inside the EU's - so far that EU also have protected the coal production. It has allowed gas consuming into cohorts of environmental and climate concerns, but it is by no means been any wonderful speed on the phasing out of the EU's own coal resource usage up till now a minimum of.

Shale Gas in EuropeNow it turns out, nevertheless, that Europe also has substantial amounts of shale gas. U.S. Geological Survey (USGSC) estimates total recoverable untraditional gas reserves (Shale Gas and CBM) might be as considerably as 400 TCF . The activity about the shale gas in Europe can consequently be larger than the classic gas development and production taking part in Europe today. (1 Trillion Cubic Feet (TCF)Â is 28.32 billion cubic meters (bcd)).A JP Morgan study speculates that the total shale resource possible for Europe is about 510 TCF. Extensive petrophysical analysis according to log data and core samples is needed for a far more accurate assessment of potential and producible shale resources. Shale resource assessment and preliminary exploration efforts are underway throughout Europe. Whereas the initial shale activity in the US was carried out nearly entirely by little independents, many international oil organizations are active in Europe, hoping possibly not to lose out on lower lease concession expenses feasible by means of early entry. Rapid progress in shale production in Europe could possibly be hampered, nonetheless,by lack of oilfield service infrastructure to supply drilling rigs for horizontal drilling and completion equipment for multistage hydraulic fracturing.Ukraine has the prospective to extract 20 billion cubic meters of shale gas a year over ten years, Kommersant-Ukraine reported, citing Mykhail Korchemkin, the head of East European Gas Analysis.A current report made by Stig-Arne Kristoffersen, estimates that the 12 basins within Ukraine could hold as significantly as 1800 TCF in location and with a 20% recovery this equates to about 350 TCF of Shale Gas resource potential inside Ukraine alone.
There is still uncertainty about the high quality of the European shale gas, but it has not prevented the significant oil organizations to pounce on opportunities. Shell is at the moment drilling for shale gas in Skåne, and says that the resources which can make Sweden self-sufficient for ten years. ExxonMobil has acquired land in Germany, Hungary, and in Poland. ConocoPhillips and Chevron are already active in Poland, and OMV tests it in Austria.The lately produced accessible US Department of Power report revealed that as noticed right now, the largest reserves of shale gas in Europe are in Poland. The authors of the report calculate that Poland has reserves of about 22,43 billion cubic meters of shale gas, of which five,29 billion m3 is immediately readily available for extracting. The majority of the shale gas is in Baltic Sea basin about three,65 billion m3, about 1,25 billon m3 within the region of Lublin Voivodeship, or Lublin Province, and next 0,4 billion m3 in Podlaskie Voivodeship. The businesses like BNK Petroleum, Talisman Energy, Marathon Oil, Chevron and Exxon-Mobil are actively drilling to find the prospective new gas nicely web sites. Probably the most potent region in shale gas in Poland may be the Baltic Basin already awarded leases to participating within the venture oil organizations. Probably the most active in Baltic basin region entrepreneurs are 3Legs Resources, subsidiary of Lane Power Poland in a joint venture with ConocoPhilips. The results of initial borings had been not publicly disclosed. Lublin Voivodeship may be the basin encircled from the north by Grójec from the west trans european cliff, from the east by Polesie Lubelskie and from the south Ukrainian border. Essentially the most active in this region is Halliburton, which in September 2010 made the first drillings for the polish consortium PGNiG. The outcomes are kept secret and confidential. Six other firms acquired concessions in that region including: Exxon-Mobil, Chevron and Marathon Oil. The last region rich in shale gas is Podlaski basin. In that region the drillings have not but been initialized. The concession for this region acquired Exxon-Mobil.A function of the shale gas is that it truly is really short way from exploration to production. When production first started coming in one place, the licensees will soon continue on the next location nearby. The development is for that reason likely to go fast.Creates its own marketThis is obviously enormously very good news for Europe and the EU. Only the effects of the U.S. shale gas has reduced Europe's gas bill and provided European clients a stronger negotiating position with Russia and other main gas supplier countries in Europe. Negotiating position will turn out to be stronger the much more Europe expects its gas production to improve. It will take a decade or two prior to there may be big volumes of it, but there are prospects for this scenario to take place.This makes it less difficult for Europe to use gas instead of coal to a higher extent than nowadays. With improved technology for gas-to-fuel developed by the major oil companies will also ultimately get a brand new delivery potential and secure fuel source.The underlying growth in demand for gas in Europe is already high, and more than sufficient to take care of lost export opportunities to the U.S.. When 1 adds the new growth opportunities, you will find good prospects that shale gas is largely "creates its own market", therefore there is still a lot of room for imports from Norway and Russia.We will either underestimate or overestimate the threat from the shale gas to conventional gas supplier countries. Both Russian and Norwegian gas is nevertheless extremely competitive in Europe. It's not that all shale gas is cheaper than standard gas, or vice versa. There will likely be a brand new competitor in Shale Gas and it should addressed with far more creativity from the classic gas suppliers.
Supplier Business opportunitiesBut for the European supplier business may be the development of an American shale gas market, and even far more the development of a European industry, really excellent news. A few of the technology needed (fractionation) is situated outside the European industry expertise, but really considerably inside. United States, and naturally Europe, has an underdeveloped tradition of horizontal drilling on land. Rig industry inside the U.S. is already growing quickly, along with the very same will likely be in Europe, and each places with demand for new technologies of exactly the kind we are extremely great at in Norway. Add to this advanced 3D and 4D seismic, reservoir interpretation, remote control, monitoring, ICT in general, and significantly else - including the capture and storage of CO2 from power plants (CCS), if we alter the technique to some thing that genuinely works.
2700 billion USD, an illusion?It really is not achievable with today's understanding to estimate the market prospective inside Shale Gas And CBM, but we fully grasp its got significant possible. The staggering amount of 2700 billion USD from wind turbines might be an illusion, even when we correct for the nuclear component, because most of this can be subsidized by government funds or from consumers. Just like conventional biofuels will wind get to meet the wall long before it is scaled up as far as many picture.It is not just since of the enormous subsidy requirements, but also since the wind will constantly must be limited by the availability of other power that may meet the need to have when there is no wind. In Europe, it means that you simply generally must have accessible coal or gas power equivalent to the gross production capacity and could be turned up and down. Most of the time it'll either produced from thermal power or wind power, after which there is going to be no net contribution to the permanent power supply. It is only when demand peaks coincides using the blows that it can be produced from each. A little added power can be obtained by utilizing the Norwegian hydro power production possible, however it makes only a distinction modest within the huge European context, especially if we use up considerably of this opportunity on their own windmills.There is also doubt about that at all there's some climate benefits of wind power if you take into consideration the elevated fuel consumption when coal or gas power plants have to run in emergency and in powering up and down periods.Because the wind is so well-known and politically right, and so far has emerged as a seemingly great climate solution, the politicians have largely supplanted the issues of backup capacity and efficiency. There's excellent reason to believe that considerably of the trigger of displacement can be a significantly stronger underlying reality of supply. Following all, wind power is an EU source with a powerful EU business. Though there would be no climate gain, windmills displacing a minimum of a modest portion of gas imports.Using the prospect of a European production of gas will alter. The EU will probably be more thinking about CCS. As this technology evolves, CCS emerge as a much more appealing remedy measures for gas (and coal) than wind power. In Germany, the "clean" wind power much less than 20% of production from the corresponding gas-fired power plants by displacing gas to the extent that the wind blows, although the CCS can take as much as 90%.With each strong arguments for subsidizing renewable are gone, biofuels and wind power should stand on its own in relation to climate policy, and they're not very solid. Within a sustainable future borders will also have space for a lot of varieties of renewable power, but not in quite huge volumes relative to total demand.When all effects included, to turn the gas for both biofuels and today's windmills climate.When the reality will kick in for Europe, and when you'll find prospects for shale gas could possibly be a key European worth creator, Europe's politicians will proclaim gas to this century's power source.
Shale gas is far more intriguing than the windEurope's focus is going to be changed from the wind to shale gas over the next decade. It's clearly not a time for politics works so that old programs and old prestigious locations ground long soon after the reality has changed. 1 will hardly alter the plans and directives just before the market has verified the shale gas prospective in Europe, but this can take place quicker than we believe.Meanwhile, it surely invested in new wind power, and to some limited degree, wind power probably also have an entitlement to long term. It is just to wish great luck to the industry to get commission from such investments.However, if it is to invest heavily and position themselves for a term of 5, 10 and 20 years, I'd be far much more cautious. Then it really is not to be "the last to obtain with us what's about to happen." When Shell already drilling for shale gas in Sweden, and it really is shale gas all the major oil companies now align themselves against, we should understand that there truly is some thing new that "is about to happen."Moreover, this can be something that has a far more thrilling technologies prospective than wind power, which appears far greater suited for the European supplier industry expertise.
Innovation and Competition hand in handInnovation Theory says that it really is where there is a technological paradigm shift that it's probable to take new leadership positions, because you will find some that are already established with leading technology. Perhaps it might be such a paradigm shift of wind at sea, but I guess is more forward than the shale gas, if it truly ever come as it seems not extremely most likely that offshore wind can free themselves from the subsidy want when land wind has not accomplished it for numerous decade. Wind power on land and shallow water is actually a mature technology with established suppliers.But for shale gas the supply industry is immature, even in the United States. In Europe, you'll find none. Moreover, this can turn out to be a lucrative market without having the need to have for significant subsidies, and it's of great importance for the assessment of political threat.Problems with contaminated ground water and gas leaks has been the boom of shale gas production in the United States into disrepute. But analysts believes it will be much more to quit the further development of shale gas. The companies don't make modifications till they get the knife on his throat, and i believe that the overwhelming focus on environmental issues related to shale gas within the United States will cause companies to learn from their mistakes and boost their technologies.The world ought to cut their CO2 emissions and one doesn't come off the gas to cut global emissions of greenhouse gases. To shift to renewable power will take a lengthy time, meanwhile, gas contribute to a more environmentally friendly power production. It's a bridge builder.It's unrealistic to think that renewable power like wind power will probably be able to solve emission problems within the short term and we can look at wind farms in Denmark which should have backup from coal power plants when the wind plant is out of order. It believed that gas and shale gas could possibly be a greater resolution within the short to medium term. The EU has ambitious plans to lessen its greenhouse gas emissions by 2020. Additionally, EU member states a desire to obtain essentially the most secure and stable energy supply. There is certainly also a industry for gas and shale gas also.Poland and Ukraine are each believed to have huge reserves of shale gas, and they're close towards the main markets in EuropeNew technologies has decreased production fees so that shale gas is now more competitive with oil and coal than it was only some years ago. Shale gas is nonetheless more expensive to create than regular gas, but not natural gas from deepwater locations as well as other marginal fields, as in the Arctic. Most of China's energy comes from burning coal. China has ambitious plans to improve its share of gas from 4 percent to eight percent of the power mix by 2015. Shale gas could play an crucial role in contributing to these targets. Chinese businesses are inside the U.S. now to learn strategies about shale gas production. A focus on shale gas can take place fast in China as when China 1st turn, so they turn

Cost of ownership for direct gas-fired dryer and for steam-heated dryer?
Our industry is textile fiber production and we use steam-heated multistage band-dryers of capacity 6t dry fibers per hour. The dryers use 10-bar steam made from gas-fired boilers. 1 ton steam is used for drying 1 ton of wet fibers. Does anybody have experiences about by which ratio a direct gas-fired dryer of same drying capacity is more cheap or more expensive than a steam-heated dryer? How much better is the total energy efficiency (heat utilisation) of a direct gas-fired dryer in comparison to a steam-heated dryer (like described above)? Your answer must not be 100% exact, at-about figures are sufficient.
