摘要
石家庄炼油厂的液化气脱硫醇装置是由国外进行基础设计,全套设备在国内制造的,其设备能保证足够的反应及沉降时间,采用鲍尔环填料和合适的填料高度,对原料液化气进行预碱洗,对循环使用的催化剂碱液用低含硫的物料进行反抽提。该装置经两年多的运转,精制后液化气的总硫含量保持在3ppm 以下。
The LPG mercaptan removal unit of Shijiazhung refinery,adopting a fore-ign basic design,was fabricated and constructed domostically.This unit ensuressafficient time for reaction and settling,adopts Pall ring packing and properpacking height for extraction,pre-alkaline washes the LPG feed,and re-extra-cts the used catalyst containing alkaline liquor with low-sulfur stream.Thisunit has been on-stream for more than 2 years with the total sulfur contentof treated LPG being kept below 3 ppm.
