油田原油气的污染问题及其引射式回收技术

Pollution of crude-volatilizing gas and recovery technique by ejectors

针对挥发至空气中的大量原油气的严重污染和能源浪费问题 ,分析了回收原油气应该解决的关键问题 ,研究了一种简单实用的多级引射式回收方法。整套系统串联的级数以 2～ 3级较为合适 ,一般不应超过 4级。

Lots of crude-volatilizing gas can come out of crude oil tanks in oil fields. The severe environmental pollution and energy waste of the gas is discussed. The key points are particularly analyzed. And the a new recovery method is put forward. The special device in this new method is matched multistage ejectors, the whole system is suitable for being connected in series by 2-3 stages, not exceeding 4 stages. This recovery technique has been available.
