低温甲烷洗工艺的冷量是由以产品气CO为工质的制冷循环所提供的，能量消耗很大。为了节省能耗以增加工艺的经济性，通过模拟计算对制冷循环进行分析研究，并根据工艺中制冷的需求与能耗的关系确定了较优的设计参数。同时，精馏塔与制冷系统的关联较为紧密，合理的设计可以降低制冷系统的能耗。

The cooling capacity of the low temperature methane-washing process is provided by the product gas CO as the working medium in the refrigeration cycling system , and the energy consumption is large . To save energy to increase the economic benefits of the process , after analyzing and studying the refrigeration cycle by simulation , the optimum design parameters are determined according to the technical requirements and energy consumption in refrigeration . In the mean time , the relationship between distillation tower and refrigeration system is so close . the reasonable design could reduce the energy consumption in the refrigeration system .
