摘要
简要论述了煤制天然气过程中采用碎煤加压气化工艺所产生的污水特点,重点阐述了污水处理的关键环节酚氨回收处理工艺。对目前广泛采用的工业技术特点进行了详细分析,并对各种技术的商业运行参数进行了比较,认为气化环节采用碎煤加压气化技术,后续废水处理过程中,酚氨回收环节选用鲁奇公司工艺技术更为安全可靠。
The characteristics of sewage comes from the process of crushed coal pressurized gasification of coal to natural gas are briefly expounded. The technologies widely applied in the phenol ammonia recovery process and the key section of the sewage treatment,are analyzed in detail. The industrial operation parameters of the different technologies are compared. It is thought that when the crushed coal pressurized gasification technology is applied in gasification section,selecting Lurgi＇s technology in the phenol ammonia recovery process of the sewage treatment will be more safe and reliable.
