摘要
原油油罐挥发气（天然气）挥发造成环境污染和能源浪费．本文提出将可编程控制器、变频调速器及二次仪表用于天然气压缩机控制、构成全自动化成套装置，为油田提供了行之有效的挥发气回收工艺手段．
The natural gas volatilizing from the crude oil tank can make pollution of the environmentand wasting of the energy. This article describes a set of automatic unit which made up of natural gas compressor controlled by the programmable controller, governer of frequency coversion and the second time displayed meter. It provids an effective way to recover natural gas in the oil field.
