【Abstract】 The rebuild of aniline recovery equipment is reclaimed in this paper. The effect of the batch rectifying of the original device has been improved. Aniline go-through within the condensing tube on top of the original tower is transformed to aniline go-through within shell pass. Therefore, the blockade due to aluminum chloride catalyst is solved. The rebuilt device has such advantage as stable production, good quality, better reclamation of aniline and less environment pollution.更多还原
