| titleOfInvention | A kind of production system of hexamethylenediamine |
| abstract | A production system for hexamethylenediamine, comprising a hydrogenation reactor, a gas-liquid separator, the number of the gas-liquid separator and the hydrogenation reactor is at least two, and the hydrogenation reactor is a gas-liquid-solid three-phase fixed-bed reactor , the side walls of each hydrogenation reactor are respectively provided with a heat exchange interlayer, the inner space is respectively provided with a heat exchange coil, the top of each hydrogenation reactor is respectively connected with the adiponitrile source through the first feed pipe, and each first The first valve is respectively set on the feed pipe, the bottom is connected with the hydrogen source through the second feed pipe, the second valve is respectively set on each second feed pipe, and the side wall of the hydrogenation reactor located at a high position passes through the third feed pipe. The material pipe is connected with the liquid-phase material source, and is connected with the side wall of the hydrogenation reactor located at a low position through the overflow pipe, and the gas-liquid separator is arranged on the top of the corresponding hydrogenation reactor. The invention has simple structure and convenient operation, can effectively reduce the mechanical loss of the catalyst, facilitates the control of the reaction temperature by enterprises, and is beneficial to the production of high-quality hexamethylenediamine products. |
