PSA Oxygen Generator design–Hangzhou Nuzhuo Group (China)

Oxygen, nitrogen and hydrogen are important molecules that make up life, matter and energy. They all have their own meanings in life. We all know that the use of medical gases can treat diseases, and emergency patients often use oxygen and other gases to save their lives. As for oxygen, I think most people can’t live without a supply of oxygen. Since our inception, the company has made these molecules a part of its research area and core business. The goal of Hangzhou Nuzhuo Group is to lead the development of the industry, create long-term performance and be committed to sustainable development.

The Pressure Swing Adsorption process for the generation of enriched oxygen gas from ambient air utilises the ability of a synthetic Zeolite Molecular Sieve to absorb mainly nitrogen. While nitrogen concentrates in the pore system of the Zeolite, Oxygen Gas is produced as a product.

NuZhuo Oxygen generation plant’s use two vessels filled with Zeolite Molecular sieve as adsorbers. As Compressed Air passes up through one of the adsorbers, the molecular sieve selectively adsorbs the Nitrogen. This then allows the remaining Oxygen to pass on up through the adsorber and exit as a product gas. When the adsorber becomes saturated with Nitrogen the inlet airflow is switched to the second adsorber. The first adsorber is regenerated by desorbing nitrogen through depressurisation and purging it with some of the product oxygen. The cycle is then repeated and the pressure is continually swinging between a higher level at adsorption (Production) and a lower level at desorption (Regeneration).
