摘要
泰钢炼焦制气厂针对粗苯回收率低的问题 ,选择最佳洗油循环量、最佳吸收温度、最佳回流量、最佳蒸汽送入量进行正交试验 ,确定工艺指标 ,并严格操作和考核 ,使粗苯回收率由 0 .7%提高到 1.11% ,年创经济效益 48万元。
In this paper,aiming at the problem of low recycle rate of crude benzene,coking gas plant of Taishan iron and steel general corporation has carried out mutual affecting test by selecting the best recycle quantity of washing oil,absorbing temperature,quantity of circumfluence and steam blowing.The plant ascertained the technical indexes,and operates and checks strictly,improving the recycle rate of crude benzene from 0.7% to 1.11%.The economic benefits of 480 thousand yuan per year can be created.
