HAZOP analysis meeting for Fufeng Jinhua furnace 3.0 for producing synthetic ammonia from lignite was held. Author/Source: Jinhua Furnace; Date: 2020-10-13; Clicks: 21. On October 12-13, 2020, the HAZOP analysis meeting for the Jinhua furnace of Fufeng Northeast Bio-Technology Co., Ltd.’s 300,000 tons/year synthetic ammonia production project was held at Saiding Engineering Co., Ltd. Relevant personnel from Hulunbuir Northeast Fufeng Biotechnology Co., Ltd., Saiding Engineering Co., Ltd., and Beijing Qingchuang Jinhua Technology Co., Ltd. attended the meeting. At the meeting, representatives from all three parties conducted a HAZOP safety assessment analysis on the Jinhua furnace. From the perspective of system safety, the hazards and operability issues of water-coal slurry gasification units were summarized and analyzed to identify potential flaws and safety risks in the gasification design, and improvement suggestions were provided through LOPA analysis. It provides a basis for the selection of gasification control systems and equipment, thereby reducing safety risks from the design stage. Lay a solid foundation for the safe and stable operation of the entire gasification unit. The 300,000 tons per year synthetic ammonia project of Hulunbuir Dongbei Fufeng Biotechnology Co., Ltd. utilizes the water-cooled wall waste boiler gasifier technology for water-coal slurry developed by Beijing Qingchuang Jinhua Technology Co., Ltd. (Jinhua Furnace 3.0). The gasification unit operates in a two-unit configuration; the gasification pressure is 6.5 MPaG, and the total gas flow rate is 85,000 Nm3/h (CO + H2). The project is located in Zhalantun City, Inner Mongolia, and is scheduled to go into operation in 2021. The gasification unit of this project uses lignite as the feed coal, with a slurry concentration of 50%. This project is another low-concentration water-coal slurry gasification unit to come online, following the gasification unit at Datang Hulunbuir Fertilizer Company. The Lignite Gasification Unit using Jinhua furnaces, adopted by Datang Hulunbuir Fertilizer Company, has been operating stably since its commissioning in July 2012; it is the world’s first coal-water slurry gasification unit that uses lignite as raw material.
