| Abstract: | The structured packing in air separation units(ASUs) provides more flexibility for its production,which benefits the oxygen plant in production ramping and energy-saving.However,the operation of ASU under non-standard conditions will affect the argon production.A mathematic model combined the design arithmetic and checkout for arithmetic has been adopted to simulate the process of an ASU working under non-standard conditions in order to obtain optimized operating parameters for argon production.The operation strategy and parameters have been verified in the Baosteel's ASUs,where the argon average pick-up rates have been increased by different extents,with an obvious performance improvement on technical and economic aspects. |
