The reporter learned from an interview with Sichuan Meifeng Chemicals Co., Ltd. on February 7 that Sichuan Meifeng independently developed the energy optimization technology for the gas head large-scale synthetic ammonia urea plant. It has completed 6 sets of equipment for production in Deyang, Sichuan and Xining, Qinghai. 200,000 tons of synthetic ammonia and 300,000 tons of urea were obtained. The practical results show that compared with the traditional process technology, the comprehensive energy consumption per ton of ammonia is reduced from 1467 kg of standard coal to 1054 kg of standard coal, a decrease of 28%; the comprehensive energy consumption of ton of urea is reduced from 1,068 kg of standard coal to 724 kg of standard coal, which is reduced. 32%. At present, the technology has been promoted and applied on 10 sets of devices, of which 6 sets are in operation, 1 set under construction and 3 sets to be built. 6 sets of industrial installations have been assessed, technical and economic indicators are better than the design value and the advanced level of the national standard, annual savings of more than 180,000 tons of standard coal, emission reduction of carbon monoxide 2.45 million tons, 3000 tons of sulfur dioxide, nitrogen oxides 2900 tons, more than 1700 tons of dust Compared with the equipment of the same scale introduced, a single set of equipment has saved investment of 300 million yuan and realized an annual profit of 140 million yuan. According to the data released by the China Nitrogen Fertilizer Industry Association, in 2011, domestic production of small and medium-sized synthetic ammonia was about 4 million tons. If these backward production facilities are transformed with this technology, they will save 6.36 billion yuan in funds and save 3.6 million tons of standard coal annually. According to Zhou Quanshui, the chief engineer of Sichuan Meifeng, the company has developed 21 advanced cell technologies and proprietary technologies through years of technological research. It has optimized the process and equipment of the device and has obtained 12 patented technologies, including patents for inventions. 4 items, 8 utility model patents. The project has developed energy-efficient natural gas conversion technology, invented the optimal combination of self-priming burners, modular heat recovery tubes, and high-efficiency thin-walled fireplaces, to increase the thermal efficiency of the natural gas conversion process from 88% to 93%. Developed an energy-saving vertical ammonia synthesis tower to minimize the power consumption in the cycle and refrigeration process; researched energy optimization technology, optimised energy consumption structure and reduced overall energy consumption in production; developed large-scale nitrogen-hydrogen/air Compressor unit, to change a single gas for the combined compression of two gases, saves investment, reduces power consumption, and has a long operating cycle. Developed high-efficiency urea synthesis towers and carbon dioxide stripper internals to increase carbon dioxide conversion and stripping efficiency. The tower tower granulation technology, which is unique to tower production of high-quality large-granule urea technology, produces large-granule urea on naturally ventilated towers. The products are even, dust-free, free from agglomerates and less nutrient loss, and are highly welcomed by farmers. . The production of synthetic ammonia and urea is characterized by high temperature and high pressure, inflammability and explosiveness, etc. The production process is complex. How to reduce energy consumption from the optimization of technology and energy has always been a problem for the nitrogen fertilizer industry.
