The plants for not cryogenic separation of gas mixtures find the wide application in various industries. In them are used pressure head (PSA) and free-flow (VPSA) circuits of pressure swing adsorptions. The concrete circuit of plant and certain constructive decisions (number of adsorbers, their sizes, form, procedure of management by them, others) are apply depending of source gas mixtures, received product, cleanliness and also of set productivity. Circuits of plants for reception pure hydrogen (from hydric gases), nitrogen or oxygen (from air), CO, CO2 and regenerative gases (mixture H2 and CO) are considered in detail. Is resulted the information on some plants «Linde AG» which till now is let out more than 500. Plants are characterized by low expenses, high reliability, full automation, block performances and many others.
