【Abstract】 Using special adsorbent, the purification experiment has been made on tail gas from caprolactam unit of Baling Branch Co., SINOPEC which produces cyclohexanone by cyclohexane oxdiation. This process is to remove organic compounds such as cyclohexane, cyclohexanone, cyclohexanol contained in oxidated tail gas. Also the study on the operating conditions and the test on adsorption-regeneration have been carried on. The results show that the adsorbent has perfect effect on adsorbing and removing organic compounds contained in tail gas and the adsorbent has good regenerating effect. This technology overcomes some shortcomings such as large retention and bad effect which exists in using activated carbon. The regenerated cyclohexane can be returned to the unit in order to be reused. So this process can increase economic benefits and has a bright prospect for industrialization.更多还原
