Oxygen is one of the most commonly used gases in the industrial gas industry. There are numerous methods to produce oxygen onsite. Industries use oxygen plants for production of oxygen which mostly use either pressure swing adsorption (PSA) or cryogenic distillation method. Both the techniques are equally good for producing onsite oxygen. PSA plants are used for producing oxygen for industrial and medical oxygen on a smaller scale whereas cryogenic oxygen systems are used for generating oxygen on a large scale. There is no denying the fact that both the techniques are effective in generating oxygen with high purity.


PSA oxygen plant works by separating oxygen and nitrogen from compressed air via process called as Swing Adsorption (PSA). We use the latest PSA technology in our fabrication of the machinery. The PSA technology uses synthetic Zeolite Molecular Sieve to absorb chiefly nitrogen. The process makes nitrogen collect into the pore system of the Zeolite, we will oxygen as a by-product. We use the best materials & components in manufacturing PSA generators that are reliable, durable and efficient. A large number of hospitals and industries use the PSA oxygen plants to meet their oxygen requirements.
Cryogenic oxygen functions by liquefying atmospheric air and separating it into oxygen and nitrogen. Cryogenic technique is used for producing oxygen on a large scale with high purity. After the atmospheric air is compressed, it is directed into the cleanup system where impurities such as hydrocarbons, carbon dioxide and moisture are removed. Afterwards, the air is passed through heat exchangers where it is cooled to cryogenic temperatures. Then, the air moved into a high pressure distillation column where oxygen is separated from nitrogen with oxygen forming at the top of the column. Oxygen is collected and moved into a low pressure distillation column where it is further distilled to meet commercial specifications.
