Harmful gas purifying method, there are four: combustion, condensation, absorption and adsorption. Physical absorption and chemical absorption difference: the former general no significant chemical reaction, can be seen as a simple physical dissolution process is reversible, does not change the nature of the gas is absorbed by desorption; the latter is associated with significant chemical reaction, and the efficiency is higher than the former, especially when dealing with low concentrations of gas. Wall-operation in the absorption of new wind ventilators, called absorbing substance is absorbed by the gas, the gas phase is not involved in the gas absorption is called falling gas absorbing liquid is called absorber.
