| titleOfInvention | Adiponitrile hydrogenation reaction system and method for treating reactor heavy blockage by using same |
| abstract | The adiponitrile hydrogenation reaction system and the method for treating the heavy blockage of the reactor by using the same are characterized in that an additional pipeline A and an additional pipeline B are additionally arranged on the basis of the conventional production system, so that the communication of connecting pipelines among a reactor feed pump standby platform, a reactor sampling tank and a return pipe can be realized when the return pipe is blocked by treatment through the opening and closing of a hand valve; the method utilizes ethanol continuously fed into the return pipe as a pressure source to form pressure in the blocked return pipe, after the ethanol is continuously fed for a certain time, the hand valve B is quickly opened to enable the pressure in the return pipe to be downwards poured in a moment and to be flushed towards the blockage, and after the operation is repeated for a plurality of times, the small-particle catalyst which is heavily blocked in the return pipe is flushed away, so that the conduction of the return pipe is realized. The system and the method of the invention solve the problem of severe blockage of the return pipe of the reactor in the non-stop state in the hydrogenation production of adiponitrile, keep the continuous production, indirectly reduce the cost and improve the production efficiency. |
