关于内压缩流程空分设备液体产品“边际能耗”的讨论

引用经济学中"边际成本"的概念,提出了空分设备生产低温液体产品的"边际能耗"概念,计算出内压缩流程空分设备中液氧和液氮产品在各种情况下的边际能耗,并将计算结果与液化装置的液化单耗进行比较,提出适当增加内压缩流程空分设备的液体产量,可以提高空分设备的流程效率。

Discussion on margin energy consumption of liquid product of inner compression process air separation plant

Here,the concept of Margin energy consumption of low-temperature liquid product generated by air separation plant is proposed on basis of the concept of margin cost in economics,the margin energy consumption of product of liquefied oxygen and liquefied nitrogen in each case of inner compression process air separation plant is calculated,the calculated result is compared with single consumption for liquefaction of liquefying unit and a conclusion is made that proper increase of the liquid output of the inner...
