Analysis of Purification Method for Accumulated Liquid of Internal Compression Process Air Separation Equipment During Hot Start-up

内压缩流程空分设备热开车积液调纯操作方法包括边积液边调纯与先积液后调纯。以马钢20000 m^(3)/h空分设备为例,介绍内压缩流程空分设备边积液边调纯操作方法特点与具体运用方法,阐述先积液后调纯操作方法的特点及对精馏工况建立的影响,分析边积液边调纯操作方法在内压缩流程空分设备中运用的优势。

The operation methods of purification of accumulated liquid in hot start-up of air separation equipment with internal compression process include purification while accumulating liquid and purification after accumulating liquid.The Ma Steel's 20000 m^(3)/h air separation equipment is taken as an example to introduce the characteristics and specific application methods of the operation method of purifying while accumulating liquid in the internal compression process air separation equipment,describe the characteristics of the operation method of first accumulating liquid and then purifying,and its influence on the establishment of distillation conditions,and analyze the advantages of the operation method of purifying while accumulating liquid in the internal compression process air separation equipment.
