摘　　要：针对炼油厂润滑油白土装置生产中白土吸附剂的加入量,采用投资少、性能稳定的小型PLC,采集基础油量信号后进行比值来控制变频器实现白土吸附剂的自动加料控制系统。About the amount of adsorbent in lube-oil clay refining unit, small-sized PLC is adopted that is tess investment and stable performance. Frequency converter is controlled by ratio to realize automatic feeding system of adsorbent after acquisition signal of the amount of base oil.
