Controlling emissions from barges, rail cars, storage tanks since 1993.

Vapor Control Equipment for Tank Degassing
  Zero CO2 or greenhouse gas emissions Zero NOx emissions Zero NOx!

New information: In only 19 months through October 2008 we condensed and recovered over 91 tons (82,500 kg) of VOC. That is 91 tons less air pollution in the air around the Houston Ship Channel and places we work.

PURGIT^® is fast and environmentally correct. We degas tanks using our proprietary system to condense the vapors rather than burning them in a combustor. Condensing is a better method of vapor control because it cleans the tank vapors as it recovers the VOC back to liquid. Mini combustors, the units pulled by pickup trucks in plants and tank farms, can not handle concentrated vapors at high flow rates. PURGIT can. Our 650 scfm (1,100 m3hr) condenser performs at 650 scfm from the first minute. Therefore rich vapors in tanks are removed faster, perhaps 10 times faster than mini combustors or IC engines. PURGIT condensers produce zero NOx or any other combustion by-products because they do not burn or combust and they do not have exhaust stacks. No process emissions and the recovered condensate can be recycled! If you think it is hard to imagine, click here and watch the video.

PURGIT^® uses multiple condensers to refrigerate the tank vapors, condensing them to liquid, which can be recycled. Non condensable gases like nitrogen are returned to the storage tank. The condensers are swapped when the pressure differential increases. This system handles many chlorinated solvents, gasoline and other chemicals. Advantages: Fast, no unprotected source of ignition, high efficiency vapor control, recovery instead of destruction. Patented.

If you want to reduce VOC emissions, recover valuable cargo wasted by burning, claim emission credits or just speed up tank cleaning, we can help. PURGIT does vapor control service work with the condenser system and we perform vapor control and degassing with our mobile equipment on marine vessels and shore tanks. Call PURGIT.
