液体吸收-活性炭吸附净化苯乙烯废气

介绍了液体吸收-活性炭吸附净化苯乙烯废气的原理.当吸收液中石油类物质占总体积的40％时吸收率最佳,小试液体吸收段对苯乙烯废气的吸收率在74％-97.6％之间,在工业净化装置中使用该吸收液,对苯乙烯废气的吸收率在60％-97.4％之间.活性炭对苯乙烯的吸附率为自重的30％.工业净化装置中,两种方法并用苯乙烯废气的净化效率在94.8％以上.该方法关键是寻找高效的吸收液和设计实用的净化装置.

Cleaning up the Styrene-containing Waste Gas by Liquid Absorption and Activated Carbon Adsorption

Based on the priciples of cleaning up by absorption and adsorption, there is an optimum removal of pollutants when petroleum substances in liquid are 40% of the total volume of absorbing liquid. The rate of absorbing the styrene waste gas in liquid absorption section was from 74% to 97.6% in a pilot plant while being from 60% to 97.4% in an industrial cleaning plant. Activated carbon can adsorb styrene from the waste gas at a rate of 30% by weight of carbon itself. In an industrial cleaning plant using a combination of the above two processes, the removal of styrene from waste gas can be over 94.8%. The key of such a process is to look for a reasonable absorbing liquid and to design a practical cleaning plant.
