The Xinlianxin new-type coal powder separation equipment solves the problem of long-term operation; it has passed the evaluation. Author/Source: Gasification World. Date: February 24, 2023. Clicks: 26. On February 18, 2023, the China Chemical Industry Environmental Protection Association held a meeting to evaluate and discuss the achievements related to coal powder separation equipment in Fuyang City, Anhui Province. Wu Gang, deputy secretary-general of the China Chemical Industry Environmental Protection Association, said that the dry powder gasification and powder separation equipment developed by Henan Xinlianxin Intelligent Equipment Company has successfully solved the problem of long-term operation; its overall technology is at the leading level in China. The flow guidance technology has been greatly improved, which effectively extends the duration of long-term operation and is highly beneficial for environmental protection efforts. He suggested accelerating its promotion and application. According to statistics, the current continuous operation cycle of traditional coal powder separation equipment in China is 1–6 months. Industry experts believe that Xinlianxin Intelligent Equipment Company has innovatively adopted various flow guidance designs to address the problem of excessively high local gas velocities in coal powder separation equipment, which can affect the equipment’s service life. This equipment was successfully applied in the renovation project of Anhui Haoyuan Chemical Group Co., Ltd. (referred to as “Anhui Haoyuan”), which aims to increase the annual production capacity of synthetic ammonia by 400,000 tons and that of urea by 700,000 tons. The bag filters for coal dust and the filters in the coal dust storage tanks have been in continuous operation for over 2 years; their performance is superior to that of similar equipment, and the emission concentration of coal dust particles is ≤5 mg/m3. The stable operation of the equipment effectively reduces operating costs, yielding significant economic and social benefits. A relevant official from Anhui Haoyuan Chemical Group Co., Ltd. said that by utilizing advanced diversion technologies, conducting comparisons of different materials, and installing explosion vent windows, Xinchongxin Intelligent Equipment Company has significantly improved the performance of the dust removal equipment in coal powder separation systems, with all relevant indicators meeting the expected standards. Anhui Haoyuan’s project to upgrade its production facilities for 400,000 tons of synthetic ammonia and 700,000 tons of urea utilizes a technology based on pressurized coal gasification in space-type reactors and carbon dioxide stripping for urea production. The facility includes units for pressurized coal gasification in space-type reactors, large-scale air separation, isothermal sulfur-tolerant shift reaction, low-temperature methanol washing, syngas compression, liquid nitrogen washing, low-pressure ammonia synthesis, carbon dioxide stripping for urea production, and wet acid removal, enabling the production of 400,000 tons of synthetic ammonia per year, which is then converted into 700,000 tons of urea. Trial operation began in November 2020. Henan Xinlianxin Intelligent Equipment Technology Co., Ltd. was established in 2020 and is affiliated with Henan Xinlianxin Chemical Industry Group Co., Ltd.
