Air separation plants(oxygen and nitrogen) - Product

Other Specification : Applying The Matures Technique Fo The Low-temperature Rectification To Separate The Atmosphere,development And Design Low-pressure Molecular Sieve To Clean Up The Air And The Turbo-expander Refrigeration Process To Further Reduce The Small And Medium-sized Air Separation Plant Power Consumption. Brief Introduction Of Technological Process 1.Air Compressor:The Air Compressor To 0.5Mpa-0.65Mpa; 2.Pre-cooling Unit:The Air Will Be Cooling In The Pre-cooling Unit To 5 -8 Degrees Celsius,and The Separation Of Water From The Air; 3.Purification:The Residual Water,carbon Dioxide And Hydrocarbons Will Be Separated From The Air In This Purifier; 4.The Air Expansion:The Air Will Be Expanded In This Expansion And Produces The Cold For The Process; 5.Heat Exchangers:The Air Will Be Cooled By The Counter-flowing Gaseous Oxygen,gaseous Nitrogen And Waste Nitrogen In The Main Heat Exchanger Of The Recitation Column Until Liquefying Temperature Of The Air.At The Same Time,the Three Counter-flowing Gases Will Be Heated Until The Ambient Temperature; 6.After-cooling:The Liquid Air And Liquid Nitrogen Are After-cooled By The Gaseous Nitrogen Before Their Being Throttled. 7.Rectification:The Air Is Rectified And Separated In The Rectification Column,Thus The Product Gaseous Nitrogen Will Be Gained From The Top Of Upper Column And The Product Gaseous Oxygen Will Be Gained At The Bottom Of Upper Column
