SF6-Air evacuation cost

SF6-Air evacuation cost

Explains how EPA requirements and high hydrocarbon costs have sparked a trend to recover and reuse vent streams from 1% by volume and up. For example, a stream of 4,500 lb (2,040 kg)/h ethylene containing 10-12% of other impurities such as isobutane, ethane and methane is not suitable for use in polyethylene production, but if the vapors are recovered, liquefied, and the ethylene stripped out ...
