HuiNeng’s Phase II coal-to-natural gas project achieved full-process operation to produce qualified liquefied natural gas. Author/Source: Hualu. Date: 2021-09-16. Clicks: 14. On September 14, the Phase II coal-to-natural gas (SNG) project of Inner Mongolia HuiNeng Coal Chemical Co., Ltd., for which Hualu was responsible for the engineering design, completed its full process and produced qualified liquefied natural gas (LNG); all units operated successfully upon initial startup with stable performance. The owner has sent special news: This project is located in the Shengyuan Coal Chemical Industry Base in Yijinhuoluo Banner, Ordos City. Its capacity is to produce 1.02 billion Nm3 of coal-derived natural gas per year, with all of it being liquefied. The total area covered by the project is about 160 hectares. It is the first demonstration project for coal-derived natural gas in China to be funded and constructed by a private enterprise. Hualu Company was responsible for the design of the project’s production facilities, auxiliary production equipment, utility systems, office facilities, and some supporting living facilities. The completion and operation of this project will fill the gap in China regarding the use of water-coal slurry gasification technology for the production of coal-based gas. It will pave a new path for the clean and efficient utilization of coal resources and for ensuring **energy strategic security**, while also providing technical guidance and a model for the development of the **coal chemical industry**. The consumption of coal, water, electricity, and other resources in this project is all below **the standard, reaching a level that is ahead of that in the industry. Among them, the gasifier in this vaporization unit is currently the largest operating coal water slurry gasifier in the world in terms of capacity. It utilizes a patented multi-nozzle opposed coal water slurry pressurized gasification technology. This unit has an effective gas (CO+H₂) production rate of 247,500 Nm3/h, a gasification pressure of 6.5 MPaG, with an inner diameter of 4 meters and a height of 26.7 meters for the gasifier ； The methane synthesis unit operates at a synthesis pressure of 5.46 MPa and a reaction temperature of 675°C; the purity of the methane in the SNG product exceeds 96.8%, with the scale of each production line being at the leading level in China ； The SNG liquefaction unit is the first SNG liquefaction unit designed and put into operation by Hualu Company. It utilizes the patented technology of \"mixed refrigerant cooling\" as well as patented multi-channel shell-and-tube heat exchangers, with the scale of each unit being at the leading level in China. Faced with complex challenges such as high design complexity, tight deadlines, and the need to carry out production and construction simultaneously, Hualu Company’s project team pooled their efforts, made thorough plans, and actively overcame these difficulties. By providing engineering design services of high standard, they laid a solid foundation for the successful achievement of all project milestones, ensuring that the project was able to start production successfully and produce qualified products. Inner Mongolia HuiNeng Coal Chemical Co., Ltd. expressed the hope that, taking the successful commissioning of this project as an opportunity, both parties will continue to work together in the future to write a new chapter in their cooperation.
