焦炉煤气低氢碳比制LNG装置运行分析

Analysis of the Running Plant that Make the Low Hydrogen to Carbon Ratio of Coke Oven Gas to LNG

介绍了年产10万t LNG,由英国DAVY公司提供焦炉煤气低氢碳比技术,内蒙古恒坤化工有限公司承建的世界首套焦炉煤气制LNG装置的运行分析。详细叙述了焦炉煤气制LNG装置的工艺流程及特点,重点介绍了装置试车过程中气柜、压缩及预净化、精脱硫、甲烷化以及干燥及液化等工段出现的问题及处理措施。

This paper introduces an annual output of 100000 tons of LNG plant running analysis, by the DPT＇s technolog by making the low hydrogen to carbon ratio of coke oven gas to LNG , the world＇s first coke oven gas for LNG plant constructed Inner Mongolia Hengkun Chemical Co. It described the process and characteristics of the LNG plant in detail , and mainly introduced the commissioning process gas holder, compression and pre purification, desttlfurization, methanation and drying and liquefaction process problems and treatment measures.
