煤制乙二醇系统弛放气处理浅析

Brief analysis of purge gas treatment in coal-to-ethylene glycol system

对草酸酯法煤制乙二醇工艺中偶联酯化弛放气和加氢合成弛放气的作用、杂质气来源,及对弛放气的处理分别进行了介绍,重点对偶联酯化弛放气的处理从原理到流程进行了详细的分析,说明了弛放气的控制和处理是煤制乙二醇工艺中重要的一环.

The effects of coupling esterification purge gas and hydrogenation synthesis purge gas,the source of impurity gas,and the treatment of purge gas in the oxalate method coal to ethylene glycol process are respectively introduced.Focusing on the coupling esterification purge gas,the treatment of purge gas is analyzed in detail from aspects of principle and process,indicating that the control and treatment of purge gas is an important part of coal-to-ethylene glycol process.
