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.

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 gel Alumina

Activated carbon

Molecular sieve

① The depth desiccation of gas and liquid ② the decolorization and deodorizer of Organic

oil products and food, medicines; ③ isomeric organic compounds (such as mixed

xylene) isolation; ④ air separation for producting oxygen-

enriched air; ⑤ removing harmful substancesfrom from the

effluent or emission
