Adsorption A component of a gas or a liquid stream is removed and adsored by a solid adsorbent.

 (1) The depth of dehydration and drying of gases or liquids.  (2) the deodorization, bleaching and solvent vapor recovery of gas and solution.  (3) the adsorption and separation of trace amounts of substances in the gas.  (4) the separation of some systems which certain distillation is difficult to separate.  (5) exhaust and waste water treatment. Adsorption operations

The indicators of adsorption are:  ① the recovery rate of adsorbate;  ② operation strength;  ③ energy consumption. Operations evaluation

 Physical adsorption: also known as the van der Waals, and it is the adsorbate and adsorbent in adsorption of Intermolecular forces.  Chemical adsorption: is the adsorbate and adsorbent in adsorption of chemical bonds between molecules. Classification of adsorption

Adsorbents are some solid materials which can effectively adsorb some components from a liquid or a gas. Adsorbent Silica gelAlumina
