What is desorption? What is the purpose of desorption? Answer: The process of separating the absorbed gas from the absorbent solution is called desorption. There are two purposes for desorption: one is to release the absorbate dissolved in the absorbent once again, thereby obtaining a purer absorbate gas ； Secondly, after releasing the absorbed substance, the absorbent can return to the absorption tower for reuse, thereby saving operating costs.

There is a dissolution equilibrium between the solute dissolved in the absorbent and the solute in the gas phase. When the solute reaches dissolution equilibrium in the absorbent, the partial pressure of the solute in the gas phase is referred to as the saturated vapor pressure of that component in that absorbent. When the partial pressure of the solute in the gas phase is lower than the saturated vapor pressure of that component, the solute escapes from the liquid phase into the gas phase, a process known as desorption. The goal is to regenerate the solution for reuse!
Desorption is the process of separating the absorbed gas from the absorbent solution； Release the absorbate dissolved in the absorbent again ； The absorbent is reused.
If the equilibrium vapor pressure of a component in the solution is greater than the partial pressure of that component in the gas mixture, the component will be released from the solution, that is, it will transfer from the liquid phase to the gas phase; this phenomenon is known as desorption.
The process of separating solutes from the absorption solution is called desorption. Purpose of desorption: to obtain the desired, relatively pure solute; solvent regeneration for reuse.

The reverse process of absorption, which separates the absorbing solvent from the solute
The process of separating the absorbed gas from the absorbent solution is called desorption. There are two purposes for desorption: one is to release the absorbate dissolved in the absorbent once again, thereby obtaining a purer absorbate gas ； Secondly, after releasing the absorbed substance, the absorbent can return to the absorption tower for reuse, thereby saving operating costs.
The process of releasing gases dissolved in a liquid is called desorption; it is the reverse process of absorption. The function of desorption is to recover the solute while regenerating the absorbent (restoring its ability to absorb solutes), and it is an important part of a complete absorption process.
