芳烃原料罐区有机气体回收装置运行问题初探与分析

Discussion and analysis on organic gas recovery device on aromatics tank

本文介绍了四川石化65万t·a-1对二甲苯芳烃联合装置配套芳烃原料罐区有机气体回收装置工艺流程简述,主要控制指标、运行状态以及运行过程中出现的问题分析及应对措施。装置运行半年来,操作稳定,外排气体烃含量小于35×10-6,远低于国家设计标准,达到安全环保要求。

The organic gas recovery device on aromatics tank for 650,000t·a-1 paraxylene aromatic hydrocarbons device was introduced. The main indexes, running state, problems and solutions were analyzed. The device ran stable for half of the year. The hydrocarbon content of exhaust gas is less than 35 ×10-6, which is way below national standard, meets the environmental safety requires.
