LAKE CITY, Pa., June 19, 2012 /PRNewswire/ -- Harmful emissions are generated during natural gas dehydration as water vapor is removed from gas using traditional Triethylene glycol dehydrators. Water vapor and other impurities must be removed from natural gas, because these impurities can damage equipment and delay or stop transportation. "It is therefore necessary to employ dehydration systems," states Tyler Currie, Western Sales Manager for Van Gas Technologies. "Economical and ecology-friendly fuel gas conditioning is the focus of our business."
Traditional technology, in the form of Triethylene glycol dehydrators ("TEG dehydrators"), allows methane, volatile organic compounds, and hazardous air pollutants to be released to the atmosphere, damaging local air quality. They also require fuel gas to heat the glycol, wasting energy.
In many applications, GasDry™ brand desiccants are the sensible alternative to TEG dehydrators. Instead of producing the emissions that result from glycol dehydration, the fuel gas conditioning process using GasDry™ brand desiccants allows water vapor to be absorbed by the desiccant tablets, which, as they absorb water, begin to dissolve. The dissolved water/tablet mixture is separated from the natural gas by gravity and exits the system as a liquid, leaving only the purified natural gas. No gas emissions escape the system.
Van Gas Technologies, a division of Van Air Inc., is the family owned business that produces GasDry™ brand desiccants for the natural gas industry. Desiccant tablet technology was originally used in the 1950s for drying compressed air. About fifteen years ago, in response to requests from the natural gas industry, Van Gas Technologies developed new formulas for removing water vapor from natural gas.
"When natural gas producers and processors use GasDry™ brand desiccants, odorous and potentially toxic emissions resulting from natural gas dehydration are eliminated," says Currie.
There are both ecological and economical advantages to using GasDry™ brand desiccants for fuel gas conditioning rather than using glycol dehydration. GasDry™ brand desiccants prevent freeze-ups, water condensation, and hydrate formation, and also meet pipeline moisture specifications under certain conditions. They are safe, effective, and environmentally sound. A gas dryer using GasDry™ brand desiccants has no moving parts to repair, produces no emissions, and needs no fuel. The EPA recommends the use of desiccant dehydrators, reporting that when TEG dehydrators are replaced with desiccant dehydrators, both emissions and maintenance costs drop.
