Abstract

The invention relates to a high-effective organic waste gas recovery processing method and complete equipment. The complete equipment includes: an organic waste gas collection apparatus, a gas storage tank, a buffer tank, a primary membrane unit, an active carbon adsorption unit, a vacuum pump, a gas-liquid separation tank, a compression condensing unit, a secondary membrane unit, a low temperature catalytic oxidizing reactor, and a tubular heat exchanger. Through the two-stage membrane as a core technology, advantages that a membrane process is high in efficient, is continuous, has high recover rate and high safety and is suitable for high-concentration organic waste gas are achieved, thus recovering the recoverable components in the waste gas; in addition, with the low temperature catalytic oxidization technology, an advantage of deep processing thereof is achieved, so that a problem of accumulation of light-hydrocarbon substances is overcome. The processing method and complete equipment not only high-effectively recover valuable organic substances, but also can perform deep processing to the organic waste gas with satisfaction of strict requirements on safety production in petrochemical enterprises. Through the deep processing to the organic waste gas, discharged organic waste gas can reach national emission standards.
