摘　　要：针对储油库活性炭吸附法油气回收装置,以活性炭吸附-真空解吸-汽油吸收的工艺流程为基础,对装置的自动控制逻辑进行设计。基于油气进气量计量系统,设计了装置"吸附-再生-吸收"过程的主控制程序,并进一步给出了真空泵轴心冷却控制和吸收塔液位PID控制的设计方法。30余座储油库3年多的运行效果表明:设计的控制系统合理有效,能够满足装置的运行要求;装置排放符合国家标准,具有显著的经济效益和社会效益。For the vapor recovery unit （ VRU ） using activated carbon adsorption method in oil depot, the automatic control logic of the unit is designed based on the technological process of active carbon adsorption-vacuum desorption-gasoline absorption. Based on the metering system of intake air, the main control program of“adsorption-regeneration-absorption” of the unit is designed, and the design method for vacuum pump axial center cooling control and absorption tower level PID control is also given. The 3-year operational effects in more than 30 oil depots show that the control system designed is reasonable and effective, it can meet the operation requirement of the unit, and conforms the national emission standard, and possesses significant economic and social benefits.
