Who tigers, the university of Manchester institute of chemical engineering, Ph.D., the international well-known chemical engineering experts, from the Royal Academy of engineering academician of John Garside, chief expert advisers to the fluid mechanics research company, "one thousand plan" of China and tianjin, experts. Founded in tianjin investec joint engineering technology co., LTD., and chairman, with "large granular ammonium sulphate production technology and crystallization device" patent technology, continuous energy saving design production of large granular ammonium sulphate crystallization process, make the ammonium sulfate crystallization technology fully upgrade, realize the comprehensive utilization of the ammonia. This process has been in baosteel chemical industry, sinopec (600028, shares) and the formation of industrialization, pangang group and baoshan iron and steel base in zhanjiang city guangdong smoothly this year to complete the project, ammonium sulphate crystallization device, gas refining project implementation technology transfer fee accumulative total of 50 million yuan. Its crystal products more than the international similar products, and energy saving of 25% or so, to upgrade the Chinese coal chemical industry technology innovation made great contributions to fill the domestic blank in the field of the technology. For the recovery of ammonia gas has a dual meaning to purify the gas and recycling materials, investec joint team developed ammonium phosphate anhydrous ammonia absorption production process innovation, from the technology and equipment to minimize pollution level, the technology at home and abroad domestic sewage by 60% - 60%, 30% energy saving operation.
