吸收解吸（Absorption desorption） The absorption desorption of.Txt single is very painful, single long more pain, a few days ago I saw a sow, it happens what is cruel? Man, I interrupted three legs; is a male dog, I cut it five legs!

The absorption process is the use of various components in the gas mixture in the liquid (absorbent) in different solubility to the separation of gas mixtures. The dissolved component called solute or absorbent, gas containing solute called rich gas, dissolved gases called lean gas or inert gas. There is the equilibrium solute dissolved in absorbent and solute in the gas phase, when solute reach dissolution equilibrium in the absorbent, the solute in the gas phase pressure is called saturated steam of the components in the absorbent pressure. When the solute in the gas phase partial pressure is greater than the saturated vapor pressures of the components, then solute from the gas phase into the solute, called the absorption process. When the solute in the gas phase partial pressure is less than the saturated vapor pressures of the components, the solute from the liquid phase to escape into the gas phase, called desorption process. Increase the pressure, lowering the temperature is conducive to solute absorptio
