China's fertilizer industry "12th Five-Year" development focus is clearly stipulated that by the end of the "Twelfth Five-Year Plan", China's nitrogen fertilizer enterprises to reduce to 200 or less, the raw material production rate reached 70%, large and medium-sized nitrogen fertilizer production capacity of more than 80%.
It is reported that the new round of innovation technology introduced by Anxi company was completed on the basis of the original National Science and Technology Progress Award IIIJD synthesis system and raw material gas alcoholation purification technology, including 5 technical contents: Large IIIJD series technology. The internals of the IIIJD4500 ammonia synthesis reactor are fully converted into high-grade (12.5Mpa, 440°C) superheated steam through the ammonia synthesis reaction heat, and 1,500kg of ammonia can be produced per ton, which can directly generate 400kwh. The second is the constant temperature and low temperature CO conversion developed for high CO gas. Reaction system. The system can produce 3.9 Mpa of ton of ammonia and 780 kg of superheated steam for power generation. The third is reduction catalyst technology. The technology can reduce the driving time for large-scale devices by about 7 days, and save the energy consumption of driving. The fourth is the technology of cyclone melting gasifier. This technology solves the use of various coal resources including anthracite, does not compete with electricity, adapts to the regional characteristics of coal resources, and continuously gasifies without exhaust emissions; 5 is a low-pressure alcohol hydrocarbonation refining technology. This technology perfectly integrates the JJD constant-temperature and low-pressure water pipe methanol tower with the alcohol alkylation refining process, and the ammonia alcohol production can be adjusted in a wide range, so that the comprehensive energy consumption of the production system can be reduced by more than 200kwh.
The five technologies launched by the company have caused repercussions in the industry. A large-scale coal chemical company in Jincheng, Shanxi Province, said that the company is located in the capital of anthracite and it urgently needs high-efficiency and environmentally friendly gasification equipment that utilizes local coal resources. The company's patented cyclone melting furnace is an ideal product, and it hopes to develop and apply it in cooperation. . Two enterprises in Anhui and Henan are constructing aerospace furnaces. Since the CO in coal gas is as high as 65% to 70%, the subsequent transformation process encounters overheating problems. It is believed that the thermostat and low-temperature conversion system of Anke company solves this problem by using the reaction heat technology. .
At present, three of the five technologies launched by Anxi have been awarded the first prize for scientific and technological advancement by the China Nitrogen Fertilizer Industry Association. This has laid a foundation for China’s large-scale nitrogenous fertilizer industry, localization of resources, energy conservation and emission reduction, and active participation in international competition. basis.
Hunan Anxuan High-tech Co., Ltd. (hereinafter referred to as Anxuan Company) has launched a new round of innovative technologies in accordance with the development priorities of China's fertilizer industry during the “Twelfth Five-Year Planâ€. This technology is seamlessly linked with the development priorities of the nitrogen fertilizer industry during the “Twelfth Five-Year Plan†period, providing technical support for the scientific development of the nitrogen fertilizer industry and energy conservation and emission reduction.
