钢铁企业深冷法大型空分氧气升压方法的合理选用

Reasonable Selection of Oxygen Pressure Rising Methods of Large Air Separation Devices Using the Deep Cooling Method for Iron &Steel Enterprises

探讨了大型空分的氧气升压的三种方式,重点分析了液氧泵内压缩流程及其优缺点,通过比较内压缩流程和外压缩流程,提出了两种流程的合理选用方案。

The three methods for oxygen pressure rising of large air separation devices are discussed, and the internal compression process for liquid pump and its advantages and shortcomings are analyzed in detail. Based of the internal compression process and external compression process, the reasonable selection plans of the two processes are put forward.
