! The third phase of Anhui Quansheng’s chemical manufacturing project, with a total investment of 3.16 billion yuan, is on the verge of completion. As reported on June 19, 2025, it was learned that the desulfurization and decarbonization, liquid nitrogen washing, and compression synthesis sections of this green and energy-efficient caprolactam production project, which are being constructed by the first company of Shaanxi Huajian Engineering Co., Ltd., have successfully achieved power supply for the integrated electrical substation, marking the entry of the project construction into its final stage. Located in the Lüqiao Salt Chemical Industrial Park in Dingyuan County, Chuzhou City, Anhui Province, this project is one of the key projects in Anhui Province for 2025. With a total investment of 3.16 billion yuan and an area of 320 mu, it includes 128,000 square meters of new production facilities such as workshops and warehouses. It employs internationally advanced green and energy-saving technologies to produce new green products such as caprolactam and diesel exhaust cleaners (vehicle urea). Shaanxi Huajian is primarily responsible for the installation of equipment, steel structures, process pipelines, electrical systems and instrumentation for tasks such as desulfurization and decarbonization, liquid nitrogen washing, ammonia synthesis, and compression, as well as the lifting of large-scale equipment. The main construction tasks for this successfully powered purification integrated electrical substation included installing 38 high-voltage distribution cabinets and 2 2500KVA transformers, as well as laying 3200 meters of power cables and 4000 meters of control cables. To date, significant progress has been made on the construction tasks. 126 units of equipment have been installed, and all 3 sets of centrifugal compressor units have been fully installed ； 120 tons were spent on the construction of ladder platforms for the equipment; the total length of process pipelines installed was 142,549 inches, of which 138,049 inches have been installed. 93 electrical devices were installed, 38 high and low voltage cabinets were installed, and 2 transformers were installed ； 100% of the overall lighting has been completed, 100% of the cable protection tubes in the entire plant have been installed, 5,090 meters of cable trays have been installed, and 100,000 meters of electrical cables have been installed. 1,100 instrumentation units and insulation enclosures were installed; 40 cabinets for the instrument DCS, SIS, and CCS systems were installed; 100% of the instrument cable protection tubes were installed; 8,010 meters of instrument cable trays were installed, and 120,000 meters of instrument control cables were laid ； The overall progress of the project is 85% complete. Anhui Quansheng Chemical Co., Ltd. was formerly the Dingyuan County Fertilizer Factory, and it is a wholly-owned subsidiary of Anhui Zhongneng Chemical Co., Ltd. The company is a comprehensive chemical enterprise focused on coal chemical processing; it also provides centralized heating for the industrial park. Its main products include liquid ammonia, hydrogen peroxide, hydrogen, urea, and methanol. The factory covers an area of 1,500 mu and is located in Luqiao Town, Dingyuan County, Chuzhou City, within Zone 2 of the Dingyuan Economic Development Zone in Anhui (formerly the Dingyuan Salt Chemical Industry Park). Quansheng Company plans to invest 3,159,498,100 yuan in building a green and energy-efficient caprolactam production facility within the Dingyuan Salt Chemical Industrial Park in Anhui. The facility will include PSA hydrogen production units, **units, caprolactam production units, sulfuric acid production units, as well as supporting facilities such as ammonium sulfate production units, ammonia storage areas, wastewater treatment plants, and various utility and environmental protection systems.
