Abstract
Government controls regulating gaseous emissions of volatile organic compounds are becoming increasingly severe in the United States. In the last ten years, allowable emissions from process pumps have been lowered tenfold in enacted regulations, and further reductions are being proposed in new regulations.
These regulatory limits can be met under most conditions by improved single seal technology using advanced materials and design techniques to lower emissions to a very low level. These areas, and enhanced environmental controls for the seal faces such as multi-port injection, are discussed in detail with laboratory test data and field examples of performance.
New regulations also propose categories such as Best Available Control Technology (BACT), which will require dual seals for sealed pumps. By using the improved single seal technology in a dual seal arrangement with a non-pressurized barrier fluid system, extremely low emissions levels can be achieved. Design parameters, test data, and field installation data are presented for these installations.
