How to increase the adsorption pressure and decrease the desorption pressure when the components of the feed gas and the temperature remain constant

With constant raw gas composition and temperature, to increase the adsorption pressure and decrease the desorption pressure, the following aspects can be considered: 1. Changing the choice of adsorbent: Selecting adsorbents with high adsorption properties, such as catalysts or molecular sieves that possess high adsorption capacity and selectivity. 2. Adjusting pressure and flow rate: Increasing the pressure and flow rate of the feed gas can increase the contact time between the gas and the adsorbent during the adsorption process, thereby improving the adsorption efficiency. 3. Optimize the cycle: Adjusting the timing and duration of the PSA system’s cycle, such as increasing the adsorption time and compression desorption time, can improve the adsorption efficiency and reduce the desorption pressure. 4. Adjusting the operating temperature: Increasing the operating temperature appropriately can enhance the activity of the adsorbent and accelerate the adsorption process, thereby increasing the adsorption pressure and reducing the desorption pressure. It should be noted that when adjusting the operating parameters, it is necessary to take into account the properties of the adsorbent as well as the economic efficiency and stability of the process, in order to achieve the best adsorption results. .
