| In addition to the commonly used such as adsorption, absorption, catalytic combustion method, thermal combustion method, there are biological reagent spray method. The purification method, according to the specific situation by the method of low cost, low energy consumption, no two pollution, do harm to benefit, fully recyclable components and waste heat. In most cases, the petroleum chemical industry is high in exhaust gas concentration, using the method of condensation, absorption, direct combustion and so on. Coating construction, printing and other industries due to the low exhaust concentration, the use of adsorption, catalytic combustion and other methods. The adsorption method is only to absorb the organic waste gas to the activated carbon or zeolite, and there is no real elimination of organic waste gas, but will produce two pollution, the need to change the treatment of waste activated carbon.
