本文以某典型钢厂的配套空分设备为例,在不同液体量下分别进行内/外压缩流程计算,得到内/外压缩流程能耗随液体比例变化的趋势,并从运行能耗、设备投资、运行安全等方面探讨了气体投资空分内/外压缩流程的选择。 Taking a typical air separation plant of a typical steel mill as an example, the internal / external compression processes are calculated under different liquid volumes, the energy consumption of the internal / external compression process changes with the liquid ratio, and the energy consumption, Investment, operational safety and other aspects of the gas investment in the air / outside the compression process of choice.
