Oil Vapor Recovery Technology by Membrane of Exhaust Emission of Gasoline Sweetening Unit

The oil vapor recovery of exhaust emission by combining absorption and membrane separation technology is proposed to gasoline sweetening unit of Qingyang Petrochemical Co.. A 100m³/h experimental unit is designed and built. The results getting from various working conditions show that the gasoline in exhaust emission decreases significantly (<25g/m³) and oil recovery rate is more than 95%.It is important to the oil vapor recovery, and can reduce oil vapor loss in refinery. It provides a new and clean method for the refinery.
