The adsorbent of the air separation unit can not adsorb the adsorbate indefinitely, and it needs to be desorbed when the adsorption capacity of the adsorbent is reached. There are four desorption methods:
1. Heating the gas will raise the temperature of the adsorbent, increase the energy of the adsorbate, and get rid of the adsorption;
2. Reduce the pressure of equipment to reduce the partial pressure of adsorbate, so as to separate from adsorption;
3. Introduce the gas difficult to be adsorbed into the adsorbent, dilute the concentration of adsorbate, thereby reducing the partial pressure of adsorbate and separating from the adsorption;
4. The more easily adsorbed gas is introduced to replace the adsorbed adsorbate.
The DEAR Air Separation Engineering Technology Team has experts and professional technicians who have been engaged in the construction of air separation projects for a long time to provide users with various engineering business process planning services, establish a systematic and standardized service guarantee system, adopt the principles of independence, science and justice, and comprehensively use the knowledge and experience of engineering technology to ensure that each link is implemented in place and handled carefully, so that customers can rest assured and satisfied.
