World-leading Rare Earth Catalytic Hydrolysis of Aminonitrile Process - Low Investment and Operation Costs, No By-products of Sodium Sulfate or Potassium Sulfate.
DODGEN has independently developed a cutting-edge methionine production process based on the rare earth catalytic hydrolysis process of aminonitrile. This process has been positioned as the most promising, green and cost-effective technical route for methionine production in the future. Starting from cyanoalcohols as the raw material, the process involves an amination reaction to synthesize aminonitrile, which is then hydrolyzed using rare earth catalysts to produce DL-methionine.
This process is different from the traditional Hydantoin method route, featuring mild reaction conditions and high atomic utilization rate. It has completely eliminated by-product salts such as sodium sulfate and potassium, realized the recycling of by-product ammonia water, significantly reduced the discharge of three wastes, and has greatly lowerd the comprehensive energy consumption and raw material costs.
DODGEN integrates its self-developed wide-channel microreactor and advanced tower separation technology at the front end of the process, ensuring highly efficient conversion from cyanoalcohols to methionine.
