摘要:

针状焦生产的预处理单元使用了溶剂萃取-连续沉降工艺。该工艺的优点是精制沥青收率高、质量稳定、溶剂消耗少,缺点是沉降系统容易堵塞,难以长周期运行。分别对脂芳比、溶剂比、沉降时间3个影响因素进行了分析。

Abstract:

Solvent extract-continuous settling process is adopted in the pre-treatment unit for the production of needle coke.This process has the advantages of high yield rate of refined pitch,stable quality and less consumption of solvent.However its drawbacks of blocking the settling system cause the system hardly run for a long time.The factors influencing the ratio of aromatic hydrocarbons to fatty hydrocarbons,solvent ratio and settling time are analyzed respectively.
