空分精馏系统最佳氩馏分位置的确定

Determination of the best position of the argon fraction in the air separation distillation system

指出在同时生产高纯度的氢、氮及粗氩产品，并带粗氩塔的空气分离双级精馏系统中，双级精馏塔的上塔存在最佳抽氩馏分位置，并介绍其确定方法。

his paper states that in the air separation two-stage distillation system with crude argon column for producing oxygen and nitrogen of hign purity and crude argon at same time,there is best position for withdrawing argon fraction in the upper column of two-stage distillation columns,and presents the method for determining it.
