摘　　要：以新疆伊犁新天煤化工有限责任公司20亿m3/a煤制天然气项目气化工艺方案的选择为例,介绍了流化床气化工艺、气化床(喷流床)气化工艺和移动床(固定床)气化工艺的技术特点;对比分析了Lurgi碎煤加压气化工艺、GSP气化工艺和Shell粉煤气化工艺的消耗指标。结果表明:①由于当地煤种成浆性较差,不宜采用Texaco水煤浆气化工艺;②从投资、运行、管理等方面综合考虑,在Lurgi,GSP,Shell 3种工艺方案中,Lurgi碎煤加压气化工艺具有一定的优势。Taking the purification process scheme of coal-made natural gas project with a capacity of 2 × 10^9 m^3/a in the Xintian Coal-Chemical Engi- neering Company Ltd. as an example, author has introduced the technical features of NHD process and low temperature methanol wash process; has com- pared the Lurge process and Linde process with the Dalian Technology and Engineering University＇ s process. Result indicates that ： （ 1 ） The low tempera- ture methanol wash process is preferable for the purification process of large-sized coal-chemical engineering project ; （ 2 ） Considering from aspects of in- vestment, energy consume, environment etc. , the Linde process has a definite superiority among low temperature methanol wash processes.
