Abstract
Adaptability of natural gas pretreatment process including desulfurization ,dehydra-tion ,decarburization ,demercuration and condensate recovery in outlying dispersed well are ana-lyzed .In order to be used in outlying dispersed well ,working characteristics of three natural gas liquefaction processes including cascade refrigeration cycle ,mixed refrigerant refrigeration cycle and expander refrigeration cycle have also been compared .The process of cascade refrigeration cycle is too complex to be suitable for outlying dispersed well .MRC refrigeration has high flexi-bility ,low energy consumption and strong adaptability ,therefore it can be used to most of outly-ing dispersed wells .Expander refrigeration is characterized by simple operation ,small occupied area and easy to be skid-mounted ,so it is suitable for stable operation conditions and higher well head pressure .So far as current technology level ,the single wells containing no sulfur ,low car-bon dioxide and low heavy hydrocarbon content are more suitable for outlying dispersed well .关键词
