乙烯装置脱丁烷塔工艺优化分析

Process optimization analysis of debutanizer in ethylene plant

乙烯装置脱丁烷塔主要分离碳四产品,通过分析影响脱丁烷塔平稳运行的因素,优化工艺控制系统、提高检修质量及优化药剂注入量等措施,实现了脱丁烷塔的稳定操作,减缓了脱丁烷塔内聚合反应的发生,保证了脱丁烷塔长周期运行。

The function of debutanizer of ethylene plant was mainly to separate C4 products. This paper analyzed the infuluence factors of stable operation of debutanizer, optimized process control system, improved the quality of maintenance and optimization of drug injection to implement the stable operation of debutanizer and slow down the debutanizer polymerization reaction so as to ensure the debutanizer for a long lead operation.
