The World's First Molybdenum Chemical Ammonia Recovery Unit Starts Operation

Recently, the world's first industrial demonstration plant for the recovery of ammonia from molybdenum chemical tail gas was completed and put into operation. The device can not only effectively solve the problem of ammonia pollution in molybdenum chemical production, but also realize the reuse of ammonia resources, and provide new ideas for the development of new technologies in the future.

It is reported that this set of molybdenum chemical tail gas ammonia recovery industrial demonstration devices is designed using the principle of "green new technology of ionic liquid method for industrial ammonia absorption and recycling". The "green new technology of ammonia absorption and recycling for industrial use by ionic liquid method" was jointly developed by Jinmo Group and the Institute of Process Engineering, Chinese Academy of Sciences, and has passed the appraisal of scientific and technological achievements. The technological achievement is at the international leading level, not only highly innovative, but also in line with the national industrial policy of energy conservation and environmental protection, with outstanding economic and environmental benefits, and has broad application prospects.

The "Green New Technology of Ammonia Absorption and Recycling by Ionic Liquid Method" uses ionic liquids with low volatility and high absorption as absorbents, and realizes the absorption and treatment of ammonia-containing gas in molybdenum chemical industry and the recycling of ammonia resources, and is equipped with corresponding equipment. , process, technology integration, and optimization provide a scientific basis and technical support for fundamentally solving the problem of ammonia pollution in molybdenum chemical production.

The main molybdenum products include molybdenum charge, molybdenum metal and molybdenum chemical products. Among them, molybdenum primary and charge products include molybdenum concentrate, roasted molybdenum concentrate, highly soluble molybdenum oxide, molybdenum oxide briquettes, molybdenum iron, etc.; molybdenum metal products include molybdenum bars, molybdenum plates, molybdenum shaped parts, and other products; molybdenum chemical industry Products include ammonium molybdate, molybdenum disulfide and so on.

Since ammonia gas is used in the production process of molybdenum products, related enterprises need to install ammonia recovery devices for environmental protection. Ammonia will not only cause greater harm to the human body, such as burning human skin, eyes, respiratory mucosa, etc., but also corrode plants, that is, it can absorb water in plant tissues, denature tissue proteins, and saponify tissue fats and destroy cell membranes. structure.
