Selection and design of vacuum pressure swing adsorption oxygen production process equipment

 

There are two methods of pressure swing adsorption oxygen production technology: one is to use high-pressure adsorption and atmospheric pressure desorption (PSA) method, which is mostly used in small pressure swing adsorption oxygen production projects, mainly used in medical, small ozone projects, military and other aspects; the other is to use low-pressure adsorption and vacuum desorption

(VPSA/VSA) method, which is mainly used in industrial steel smelting, medium and large ozone projects and cement industry. Compared with PSA oxygen production process, VPSA oxygen production process has two advantages: one is that it can improve the purity and recovery rate of product oxygen, and the other is low energy consumption and less adsorbent. Therefore, when the raw air pressure is low and high-pressure oxygen is not required, it is more suitable to choose VPSA.

Selection of program-controlled valves

The vacuum pressure swing adsorption oxygen production process is realized by switching program-controlled valves. The reliability and sealing of program-controlled valves are the most critical links in the vacuum pressure swing adsorption oxygen production technology. The cycle of the vacuum pressure swing adsorption oxygen production device is very short, about 30 seconds, requiring the program-controlled valve to be able to open and close quickly in a very short time. Therefore, the general requirements for the program-controlled butterfly valve of the vacuum pressure swing adsorption oxygen production device are:
(1) The closing time is less than 1.5 seconds;
(2) The valve operates reliably, and the number of trouble-free switching times is greater than 2 million times;
(3) The valve seal is leak-free.
At present, the butterfly valves used in vacuum pressure swing adsorption oxygen production devices are mainly two-eccentric butterfly valves and three-eccentric butterfly valves. The two-eccentric butterfly valve adopts the position sealing principle; the three-eccentric butterfly valve is a metal hard seal and adopts the torque sealing principle. It can withstand higher pressure than the two-eccentric butterfly valve, has a smaller opening and closing torque, better sealing performance, and a higher price.

What industries are VPSA oxygen generators suitable for?

OEM Vpsa Oxygen Generators are widely used in many industries such as medical, chemical, metallurgy, food processing, wastewater treatment, etc. They are able to provide a stable supply of oxygen to meet the needs of different fields.

What is a VPSA oxygen generator?

A VPSA (Vacuum Pressure Swing Adsorption) oxygen generator is a device that uses vacuum technology to extract oxygen from the air. It uses a molecular sieve material to absorb nitrogen under low pressure through a pressure swing adsorption process to separate oxygen. VPSA systems are generally high-efficiency and low-energy, making them suitable for large-scale oxygen production.
