净化空气中微量苯及其衍生物的研究

Research in Purification to Purify the Air from the Trace Benzene and Its Derivative

从空气中净化微量苯及其衍生物是环保方面的一个重要课题。我们在填料式吸收塔和旋膜式脱吸塔等装置中,首次采用环丁砜吸收剂进行中试,获得了满意的结果。用此法处理含有200～1500mg/NM^3苯或二甲苯的空气,可以达到国家排放标准。

To purify the air from trace benzene and its derivative, is an important problem in the aspect of environmental protection, We had Carried on a middlesized test with the packed tower as absorber and the rotating-film tower as desorber. In this test, the Cyclobutyl-sulphone was adopted as absorbent initially, then a satisfactory result was obtained. When the Content of benzene and/or Xylene in the air is 200～1500mg/HM^3, through this means, the result can come up to the national standard.
