What is the principle of PSA recovery and release gas?
Adsorption is performed under increased pressure and desorption is performed under reduced pressure. Due to the short cycle period, the adsorption heat has no time to dissipate and can be used for desorption. Therefore, the adsorption bed temperature changes caused by the adsorption heat and desorption heat are generally not large, and the fluctuation range is only a few degrees, which can be approximately regarded as an isothermal process. Commonly used vacuum adsorption methods include the following. The purpose is to reduce the partial pressure of the adsorbed components on the adsorbent and regenerate the adsorbent. Domestic Southwest Research Institute of Chemical Industry and Sichuan Tianyi Technology Co., Ltd. are companies with superior technology, good performance, and independent intellectual property rights.
It uses van der Waals force to selectively adsorb under pressure, and the gas is desorbed after the pressure is reduced! The gas is not continuous from a certain adsorption tank, but there are several tanks that are continuous when viewed as a whole.
PSA (PRESSURE SWING ADSORPTION, referred to as PSA) is a physical process that is approximately isothermal. It utilizes the different adsorption capacities of different components in the gas medium on the adsorbent. The adsorbent selectively adsorbs when the pressure increases and is desorbed and regenerated when the pressure decreases.
