HAZOP review meeting for the water-coal slurry gasification unit of Shaanxi Qingshui Yinquan Coal Industry’s melamine project held. Author/Source: Jinhua Lvu. Date: 2022-01-22. Clicks: 26. From January 17 to 20, 2022, a HAZOP review meeting was held for Shaanxi Qingshui Yinquan Coal Industry Development Co., Ltd.’s 2x60,000-ton per year melamine production project. Due to the pandemic, this meeting will be held via video conference, during which a HAZOP safety assessment analysis was conducted on the Jinhua furnace. From the perspective of system safety, the 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 2x60,000 tons per year melamine project of Shaanxi Qingshui Yinquan Coal Industry Development Co., Ltd. utilizes the water-cooled wall waste boiler gasifier technology for coal slurry developed by Beijing Qingchuang Jinhua Technology Co., Ltd. (Jinhua Furnace 3.0). The gasification unit operates in a two-in-one-backup configuration, with a gasification pressure of 6.5 MPaG; the effective gas production capacity per furnace is 100,000 Nm3/h (CO + H2). The construction site is located in the Qingshui Industrial Park, Yulin City, Shaanxi Province. Jinhua Furnace 3.0 is a new gasification technology with complete independent intellectual property rights. It achieves for the first time a direct connection between the water-cooled wall gasification chamber of the water-coal slurry furnace and the radiant waste boiler, breaking foreign monopolies in the technology for recovering waste heat from syngas produced in water-coal slurry gasification furnaces. Compared with similar technologies at home and abroad, Jinhua Furnace 3.0 improves the system’s thermal efficiency while also enhancing its adaptability to different types of coal. It provides the technical infrastructure necessary for the efficient and clean utilization of various carbon-containing solids, including those with high ash, sulfur, and calorific value content. It offers advantages in terms of energy consumption and environmental performance, as well as in system reliability, investment costs, and operating expenses.
