| titleOfInvention | Method and equipment for production of adiponitrile from adipic acid |
| abstract | The invention relates to a method and equipment for production of adiponitrile from adipic acid, and mainly solves the problem of unstable product quality in the prior art for production of adiponitrile from adipic acid. The method employs materials of fusing adipic acid, ammonia, phosphate and a diluent. The production method is as below: mixing phosphoric acid with the diluent in a pipeline mixer; conducting neutralization of adipic acid and ammonia in a cyanation reactor; sending reaction products into the bottom of a separation tower for separation; recovering gas phase of light components from an outlet; sending the diluent recovered by a gas lifting plate into the pipeline mixer, mixing the diluent with phosphoric acid in the pipeline mixer, and sending the mixture into the cyanation reactor to dilute adipic acid; and sending a liquid phase to a scraper type evaporator. The employed equipment includes an adipic acid storage tank, an ammonia compressor, a cyanation reactor, a pipeline mixer, a separation tower, a tail gas removal tower, a phosphoric acid storage tank and a scraper type evaporator. The invention has the advantage of a good quality of the produced adiponitrile product. |
