Abstract

The invention provides a post-treatment method and device for methionine preparation. The post-treatment method comprises the treatment steps of filtration, acidification, gas-liquid separation, methionine separation and saturated-state acidification column regeneration. The methionine separation is performed by adopting an electrodialysis separation device or a stripping tower or alkaline resin acidification device. The hydrolysis step is that feed liquid is led to a material pipeline port at the bottom of the acidification columns and continuously passes through three serially connected acidification columns. The post-treatment device for methionine preparation comprises a filtering device, an acidic resin acidification device, a gas-liquid separation tank and a methionine separation device. For treatment of methionine production filtrate, new substances are not needed to be instructed. The energy consumption is reduced by 90%. Potassium formate can be taken out from the filtrate, and the filtrate can be beneficially circulated. A large amount of wastewater containing low-concentration formic acid is not produced, and environmental protection pressure is reduced.

Description

technical field

[0001] The invention belongs to a separation method of chemical products, and relates to a post-treatment method and device for preparing methionine, in particular to a separation method and a special device for extracting filtrate of methionine. Background technique

[0002] Methionine is one of the essential amino acids that constitute the human body. It participates in the synthesis of proteins and is widely used in the fields of medicine, food, feed and cosmetics. The molecular structure of methionine contains a methyl group, which detoxifies toxic substances or drugs through methylation, and can be used to prevent and treat chronic or acute hepatitis, cirrhosis and other liver diseases. At the same time, it is used as a feed additive in the largest amount. Studies have shown that adding methionine to animal feed can promote the absorption of nutrients by animals, thereby promoting the rapid growth of animals, shortening the feeding cycle, and increasing ...
