Description:
Following the preliminary of air in the lower column, at the bottom of lower column obtain liquid air, and the pure liquid nitrogen at the top is as reflux liquid. The liquid air and liquid nitrogen from lower column goes into liquid air/liquid nitrogen subcooler E2 to be subcooled, and then sent to the corresponding position of upper column. After the further rectification in the upper column, product oxygen is obtained at the bottom of upper column, and goes into oxygen pipe net. The pure nitrogen gas withdrawn from the top of upper column goes out of cold box after being rewarmed in subcooler and main heat exchanger.
Applications:
- Inert Gas
- Filling Gas
- Cutting Gas
- Fuel Gas
- Tempering Gas
- Metallurgy
- Balance Gas
Competitive Advantage:
- Widely sales around the world
- Economization of energy,
- Rich historical experience over 60 years
- The detailed stress analysis and strength calculation of the cold box for fractionating column are performed according to the geologic conditions at the client’s site to ensure the safety of cold box.
- The main pipelines located inside cold box are analyzed for stress and made of high strength aluminum alloy to maintain the pipeline undeformed. The supports for pressure vessels, valves and pipelines are made of stainless steel to maintain the strength at low temperature and reduce the loss in heat conduction.
