摘要:

近年来乙烯装置受原料多样化影响,急冷水出现乳化问题,同时系统的苯系物残留量越来越多,导致工艺水系统出现严重聚合现象。工艺水出现聚合后不仅导致急冷单元多个换热器堵塞,严重时可能导致急冷单元停工,成为乙烯装置长周期运行的主要瓶颈之一。通过在急冷水系统使用一种新型药剂来改善水质,缓解水系统乳化和结垢问题,有效延长乙烯装置运行周期。

Abstract:

 In recent years, affected by the diversification of raw material to ethylene plant, the emulsification of quench water occurred. More and more benzene series remain in the system, leading to serious polymerization in process water system. The polymerization of process water not only leads to the blockage of multiple heat exchangers in the quench unit, but also may lead to the shutdown of the quench unit in severe cases, which becomes one of the main bottlenecks for the long-term operation of ethylene plant. A new reagent is used in the quench water system to improve the water quality and alleviate the emulsification and fouling problems of the water system, thus effectively prolonging the operation period of the ethylene plant.

Key words: quench water, emulsification, fouling, demulsifer and scale inhibitor
