Finally, you will find a solution to the situation of ammonia-containing wastewater therapy due to coal coking and gasification in the coal chemical substance business. Tsinghua University's Division of Substance Design, Connect Professor Tang Zhigang presided over the introduction of "great-effectiveness ammonia-smelting incorporation technological innovation" with independent mental house privileges. This progressive technologies have substantial vitality-preserving and contamination-reducing outcomes. This has been effectively put on a lot of groups of commercial products, and has built up greater than 30 mil yuan. The economic application and benefits promotion leads are guaranteeing. Crude oil and natural gas prices remain high, making low-cost coal a chemical substitute for raw materials, but coal chemical industry must be developed to solve relevant environmental problems. Tang Zhigang launched that ammonia-that contain wastewater from coal coking and gasification generally consists of unstable ammonia, set ammonia, sulfide, cyanide, naphthalene, other, phenol and tar substances. It can be significantly polluted through the atmosphere and has to be reused and biochemically dealt with by the end. After the release. The ammonia process of recovery is primarily realized by steaming ammonia. The standard ammonia distillation approach has reduced productivity, great energy usage, significant products corrosion, large routine maintenance, and inadequate working atmosphere, specifically the removing of ammonia nitrogen, which can really affect the following biochemical remedy, causing elevated air pollution of the released wastewater. Therefore, it is actually of fantastic relevance to research and develop a new procedure of ammonia water loss to attain successful nice and clean power-saving generation. Tang Zhigang's investigation crew has consistently carried out technical improvement about the technological investigation results accrued throughout the years, and it has carried out scientific integration and innovation on the problems current inside the distillation technique of ammonia-that contain wastewater in coal compound sector. They simulated and calculated the specific creation procedure from the method simulator software, and established the optimized process design and operation factors; replaced the grid or valve plate found in the initial products with all the likely golf hole dish with impartial mental property proper rights of Tsinghua School. According to the concentration of corrosive medium in the tower, improving the equipment Value for money, improve the heat mass and transfer transfer efficiency of vapor-liquid contact, thereby reducing energy consumption; replacing the original direct steam heating with indirect heating to reduce wastewater discharge; using different materials. With the integration of the aforementioned systems, this achievement has accomplished substantial rewards with regards to source of information efficiency, energy saving, HEDP 60 enviromentally friendly security and product high quality. It really is noted that after adopting this built-in modern technology, some enterprises preserve about 80,000 plenty of steam each year compared with conventional functions, and produce about 70,000 tons of sewage annually. The functioning setting of staff has become greatly enhanced.
