摘要
介绍了变换冷凝液汽提装置在保证气化和变换运行稳定性中的作用,并结合项目实践分析了汽提装置运行中的痛难点。针对某大型IGCC煤气化项目的优化,提出了一体式闭式汽提流程有助于解决变换汽提装置运行的问题,实现气化和变换水系统氨氮含量的有效控制,同时起到良好的节能降耗效果并降低业主运行维护的成本。
Role of the CO shift condensate stripping unit in ensuring the stable operation of coal gasification and CO shift units is introduced,and the troubles in the operation of the stripping unit are analyzed in combination with the project practices.Aiming at the optimization of a large-scale IGCC coal gasification project,the integrated closed single-column stripping process is proposed to help solve the problems in the operation of the CO shift condensate stripping,and realize the effective control of ammoniacal nitrogen content in the water system of coal gasification and CO shift units.In addition,it has a good effect of energy saving and consumption reduction with reducing the cost of operation and maintenance of the owner too.
