【Qinghua Furnace】Uses 4.0MPa fluidized-bed gasification; an important milestone achieved in Xinjiang Qinghua’s coal slime comprehensive utilization project. Author/Source: Gasification World. Date: May 9, 2023. Clicks: 27. On April 30, 2023, the pouring of 7,300 cubic meters of concrete for the foundation of Xinjiang Qinghua Energy Group’s coal slime comprehensive utilization project officially began. At 19:58 on May 1, the pouring of the foundation slab was completed successfully, 36 hours ahead of schedule. The Xinjiang Qinghua slime coal comprehensive utilization project aims to develop Qinghua furnaces that are suitable for the coal quality found in coal mines, and that feature low energy consumption, low costs, and reduced wastewater generation, thereby addressing the issue of slime coal that cannot be utilized in the coal-to-gas industry. 4.0 MPa fluidized bed gasification is used. The Qinghua furnace was jointly developed by Xinjiang Qinghua and Shanghai Bicheng Technology Co., Ltd. The Qinghua furnace will address the major issue in the coal-to-gas industry of being unable to handle foamed coal, thereby breaking the technical monopoly held by the Lurgi furnace. In February 2022, Saiding Company signed a contract with Xinjiang Qinghua Coal-to-Gas Company for the \"Design Contract for the 4.0Mpa Fluidized Bed Gasification Unit of the Comprehensive Utilization Project of Slurry Coal by Xinjiang Qinghua Energy Group – Qinghua Furnace Construction.\" The coal-to-natural gas project of Xinjiang Qinghua Group is located in the Yidong Industrial Park in Yining County, Xinjiang Autonomous Region, and it is the first coal-to-gas demonstration project in Xinjiang to receive **approval. The total scale of the project construction is 5.5 billion cubic meters, with construction carried out in four phases. The first phase of this project, with an annual production capacity of 1.375 billion cubic meters of coal-to-natural gas, came online in November 2013. The Qinghua coal-to-natural gas project utilizes pressurized coal gasification (8 Ruhr gasifiers, 7 in operation and 1 as backup), sulfur- and oil-resistant shift reaction, low-temperature methanol washing, and Danish Topsoe methanization technology. Project Review: On the afternoon of January 11, 2022, Xinjiang Qinghua Coal-to-Gas Division and Shanghai Bicheng Technology Co., Ltd. held a signing ceremony for the contract regarding the design of the process package for the “Qinghua furnace” in the conference room on the fourth floor of the Qinghua Purification Building. To completely resolve the issue of imbalance between lump coal and pulverized coal in the Xinjiang Qinghua coal-to-gas project and improve its economic efficiency, the Xinjiang Qinghua Coal-to-Gas Division conducted comparisons among various technologies such as high-pressure fluidized bed and gas-flow bed. After considering factors such as technical feasibility, economic benefits, and compatibility with subsequent equipment, it was decided to collaborate with Shanghai Bicheng Technology Co., Ltd. to jointly develop the \"Qinghua furnace\" – a system that suits China’s national conditions, takes into account the quality of coal used in mines, and features low energy consumption, low costs, and reduced wastewater generation. “The Qinghua furnace features wide coal variety adaptability, low wastewater pollution, and low investment. ““The Qinghua furnace not only addresses the major issue of coal cinder that cannot be processed in the coal-to-gas industry, but also breaks the technical monopoly held by the Lurgi furnace. The introduction of this new furnace marks that Xinjiang Qinghua Group will occupy a leading position in terms of technology and innovation among domestic coal-to-gas manufacturers, which is of great significance both for the company’s history and for the history of the industry as a whole. Xinjiang Qinghua Coal-to-Natural Gas Project produces 1.3 billion cubic meters of natural gas through coal pulverization pressurized gasification (8 Lurgi gasifiers, 7 in operation and 1 as backup), sulfur- and oil-resistant shift reaction, low-temperature methanol washing, and Danish Topsoe methanation technology. Driving in 2013. Xinjiang Qinghua Energy Group. China Qinghua Group was established in 1998 and has since grown into a large, comprehensive private enterprise group that operates across various industries and provinces, covering areas such as mining, ore processing, coking, coal chemical manufacturing, metallurgy, steel production, and logistics. It has set up subsidiaries including Inner Mongolia Qinghua Group, Qinghai Qinghua Group, Ningxia Qinghua Group, and Xinjiang Qinghua Energy Group. Xinjiang Qinghua Energy Group Co., Ltd. is a wholly-owned subsidiary of China Qinghua Group. Established in May 2009, it is a large-scale enterprise group that focuses on the modern coal chemical industry, integrating resource development, chemical production, and investment and trade activities. As Xinjiang’s first coal-to-natural gas project to receive **approval**, Xinjiang Qinghua Group took advantage of the region’s abundant coal and water resources to establish its operations in Ili in March 2009. At a total investment of over 30 billion yuan, it built the Qinghua Coal Chemical Circular Economy Industrial Park at a pace often referred to as the “Qinghua speed”. The projects included a coal-to-natural gas facility with an annual production capacity of 5.5 billion cubic meters, a coal tar hydrogenation plant with a capacity of 600,000 tons per year, an ammonia synthesis plant, a thermal power plant for comprehensive utilization, and a cement production plant that uses 2 million tons of fly ash per year.
