富二氧化碳废气生产液体二氧化碳节能探讨

Energy conservation for liquid CO_2 production from CO_2-rich exhaust gas

二氧化碳排放是由人类活动引发的温室效应的最主要因素,但二氧化碳也是一种有用的资源,应用领域十分广泛。二氧化碳的回收利用问题是目前低碳经济最为重要的举措之一,而液体二氧化碳生产过程的能耗研究也具有十分重大的意义。通过低压富二氧化碳废气回收生产液体二氧化碳装置的工艺分析,确定最佳操作压力作为该类装置节能的重要措施。

The largest （manmade） contributor to the greenhouse effect is CO2 gas emissions, however, CO2 is also a useful resource with widespread application. The recycle and reuse of CO2 is vital for developing low-carbon economy, and energy conservation for liquid CO2 production from CO2-rich exhaust gas is a significant measure. Based on the analysis on production process and equipment for liquid CO2 production from low pressure CO2-rich exhaust gas, the equipment operating pressure was determined to be the most influential factor for energy conservation.
