A tail gas venting tank for the hydrogenation reduction process of aniline production

Abstract

This utility model discloses a tail gas venting tank for the hydrogenation reduction process of aniline production, relating to the field of aniline production technology. It primarily addresses the problem of high concentrations of aniline and low-boiling-point compounds in the mixed gas discharged during aniline production, and the risk of outside air being drawn into the production system under abnormal operating conditions. The tank includes a main body with a gas inlet pipe and a gas outlet pipe connected to its top. The main body contains an absorbent liquid. The lower end of the gas inlet pipe extends downwards below the surface of the absorbent liquid. Multiple sets of exhaust holes are provided on the side wall of the gas inlet pipe below the absorbent liquid surface, and the lower end face of the gas inlet pipe has serrations. This utility model provides a tail gas venting tank for the hydrogenation reduction process of aniline production, which can absorb aniline and low-boiling-point compounds in the mixed gas, reducing environmental pollution; it also prevents the risk of air entering the system.
