Air Separation Unit

Cylinder Filling ASU Plant
Air separation units (ASU) are used in a variety of fields to produce high purity oxygen, Nitrogen, argon, and other rare gases through a combination of adsorption purification, cryogenic distillation, and internal compression of high-pressure products. This process plays an important role in the production of electricity, pharmaceuticals, and chemicals. Due to lower energy consumption and fewer operational risks this process reigns supreme among others. Air separation unit manufacturers in India like Brise Chemical produces the creme de la creme of cylinder filing ASU plant in India.It allows you to maximize your return on investment while meeting all of your process requirements. The stable operation and dependability of the cylinder filing ASU plant in India mean that once commissioned, all you have to do is let it run at peak performance. It helps in reducing energy consumption vastly on one hand while also lowering operational costs on the other, thus eliminating the risk of downtime.

A cylinder filing ASU plant in India can produce 100 to 5,000 tonnes of oxygen per day with purity levels ranging from 95% to 99.5 percent or higher.

The Following Are the Main Steps in the Air Separation Process:

  • Filtration is used to remove dust and other impurities.
  • Compression Which compresses air between 4 and 150 Bar g with inter-stage cooling temperature assembly for lower the temperature rise.
  • Removal of Contaminant By using a constantly regenerated molecular sieve bed it removes any remaining water vapor, hydrocarbons, and carbon dioxide that would freeze and plug the Cryogenic equipment
  • Heat Exchange In which air is passed through integrated heat exchangers and cooled against product and waste cryogenic streams to produce oxygen and nitrogen-enriched liquefied air. This is accomplished through the use of refrigeration in separate low- and high-pressure distillation columns.
  • Product Compression Which compresses oxygen to a predetermined settled
  • Storage involves storing the liquid oxygen produced by the ASU in cryogenic insulated storage tanks.
