本文利用切换板式中返回气之和即是空气进入量这一基本点及热焓的可加性,并运用空气i-t图推演了一套新的计算方法;并对膨胀量及膨胀温度、CO2不冻结性等问题作了探讨。同时以法国650O标米3/时空分设备为例进行了演算,发现其板式长度与国内以往计算不同。本文是作者“全低压空分装置相对挥发度法精馏计算”一文(刊《深冷技术》1979年第2~3期)的继续。图 9、表17、参考文献22。
In this paper, we use the sum of the returning gas in the switching plate, which is the basic point of air entrainment and the additivity of enthalpy, and using air it diagram to deduce a new set of calculation methods. And the expansion and expansion temperature, CO2 Freezing and other issues were discussed. At the same time to France 650O standard meter 3 / time-space equipment as an example for the calculation and found that the plate length is different from the previous calculation. This article is the author of “low pressure air separation unit relative volatility method of distillation calculation,” a article (“Cryogenic Technology” 1979 2 to 3) to continue.
