On February 14, the results of the bidding for the EPC general contract project for the purification and impurity removal equipment, as well as all the auxiliary facilities in the plant; the salt separation and crystallization equipment; and the finished product warehouse, under the **Energy Group’s Ningxia Coal Industry project for the treatment and resource utilization of concentrated brine, were announced. 01 Purification and impurity removal equipment, as well as EPC general contracting for all auxiliary facilities throughout the plant: The winning bidder is Donghua Engineering Technology Co., Ltd. The contract value is 268,888,888 yuan. This contractor is responsible for the detailed engineering design, procurement, and construction of all aspects related to the project, including the purification and impurity removal of concentrated brine, removal of silicon and fluoride, high-salt catalysis, power distribution rooms, office buildings, central control rooms, and other auxiliary facilities; as well as external plant projects (excluding rigid landfills). This includes work in various fields such as process engineering, site planning, static equipment, dynamic equipment, pipelines, civil engineering (structure/construction), instrumentation and automation, electrical systems, telecommunications, HVAC, water supply and drainage, fire protection, analysis and testing, safety, environmental protection, and occupational health and safety. 02 EPC General Contracting for Salt Separation and Crystallization Equipment and Finished Product Warehouse: The winning bidder is Donghua Engineering Technology Co., Ltd. The contract value is 212 million yuan. This contractor is responsible for the detailed engineering design, procurement, and construction of all aspects related to the salt separation and crystallization processes in the project aimed at improving the utilization of concentrated saltwater; as well as those related to the finished product warehouse and the facilities in the surrounding area, such as circulating water stations, heat exchange stations, chemical dosing areas, initial rainwater tanks, and accident storage tanks. This includes work related to process design, site layout, static equipment, dynamic equipment, pipelines, civil engineering (structure/construction), instrumentation and automation, electrical systems, telecommunications, HVAC systems, water supply and drainage, fire protection, analysis and testing, safety measures, environmental protection, and occupational health and safety. **The total area of the concentration, salt separation, and resource utilization renovation project of the Coal-to-Oil Branch of Ningxia Coal Industry Co., Ltd., an energy group, is approximately 10.96 hectares (of which the area occupied by the salt separation and resource utilization facilities is about 133 mu, and the area of the rigid landfill is about 27.5 mu). The project uses the high-salinity water generated as a by-product of coal-to-oil production as raw material, and it is capable of producing 131,200 tons per year of sodium sulfate, 19,400 tons per year of sodium chloride, and 21,200 tons per year of miscellaneous salts. The construction scope of this project includes: purification of concentrated brine to remove impurities, silicon, and fluorine, as well as high-salt catalysis and salt separation crystallization. It also involves the construction of a rigid landfill site, along with utility and auxiliary facilities, such as a circulating water station, plant-wide power supply and distribution rooms, control rooms and cabinet areas, finished product warehouses, lubricant storage areas and waste oil storage spaces, spare parts warehouses, plant-wide water supply and drainage systems as well as fire protection facilities, plant-wide telecommunications systems, office buildings and central control rooms, roads outside the plant, external pipe galleries and pipelines, etc. The utility services required for the project, such as water, electricity, steam, air, and oxygen, are provided by the Coal-to-Oil Branch. **The 4 million tons per year coal indirect liquefaction demonstration project of Ningxia Coal Industry Co., Ltd., an energy group, is an industrialization demonstration project for coal-to-oil production that was approved for construction during the 12th Five-Year Plan period by the National Development and Reform Commission. The total investment in this project is approximately 55 billion yuan. The core technologies used include the iron-based high-temperature slurry-bed Fischer-Tropsch synthesis technology developed by China Science Synfuels Technology Co., Ltd., as well as the “Shenning Furnace” dry coal powder pressurized gasification technology developed by Ningxia Coal Industry Company. On December 28, 2016, the project was successfully tested in a single attempt, with the entire production process functioning properly and qualified oil products being produced. The annual output of oil products amounts to 4.05 million tons, of which 2.73 million tons are diesel, 980,000 tons are naphtha, and 340,000 tons are liquefied gas. Two oil production lines with a capacity of 2 million tons each have been built, enabling the conversion of 20.46 million tons of coal per year.
