我在多年的工作中,对下面几个技术问题有些体会,这几个问题均比较具体,也比较小,现将它们汇总成文,请各位专家指正。 1氧氮产品1:3工艺流程氮气如何取出 1.1一般空分设备氧氮产品产量为1:1或1: 2,而1:3的情况很少,但最近,炼油厂对氮气需求数量急剧增加,故希望将氧、氮比例调整到1:3; During my many years of work, I have come to understand some of the technical issues below. These are all quite specific and relatively small issues. I will summarize them now and ask the experts to correct me. 1 Oxygen Nitrogen Products 1: 3 Process How Nitrogen Is Removed 1.1 General Air Separation Equipment Oxygen and Nitrogen production is 1: 1 or 1: 2 compared to 1: 3 but recently the refinery has a dramatic increase in the demand for nitrogen , So I hope the oxygen and nitrogen ratio adjusted to 1: 3;
