This web site describes an Air Pollution Control System and a Service for Owners of Petroleum;Storage Tanks and Marine Petroleum Transport Vessels. We are in business to help you with pollution control.

PURGIT has mobile systems for vapor control. A proprietary system uses a low temperature condenser and a blower to condense tank vapors. The system recirculates tank vapors through the condensers and back to the tank allowing no VOC emissions. Zero NOx with no unprotected source of ignition.

Go to www.purgit.com , the PURGIT home page and click;on the file "Zero NOx emission control systems" and "Refrigerated vapor condenser" on the left column for more information. If you need to control VOC emissions during tank cleaning, or if you have regulatory problems from cargo transfer we may be able to help.
