Construction Location: North side of Zhongshugang Road, Gangcheng Industrial Park, Huanghua City, Bohai New Area, Cangzhou City, Hebei Province

Existing Facilities: The main production units include heavy traffic asphalt production facilities with capacities of 1.5 million tons per year, 3.5 million tons per year, and 5 million tons per year; a 1 million tons per year delayed coking unit; a 1 million tons per year hydroprocessing unit; a 1.5 million tons per year aviation fuel hydrogenation unit; a 1 million tons per year continuous reforming unit; a 1.6 million tons per year hydrocracking unit; a 2.6 million tons per year residue hydrogenation unit; a 1.6 million tons per year catalytic cracking unit; an 800,000 tons per year gasoline hydrogenation unit; a 2.2 million tons per year diesel hydrogenation unit; a 1.4 million tons per year diesel hydrogenation and upgrading unit; a 300,000 tons per year C5/C6 isomerization unit; a 150,000 tons per year light hydrocarbon recovery unit; a 40,000 tons per year MTBE production unit; a 150,000 tons per year isooctane production unit; a 300,000 tons per year gas separation unit; sulfuric acid production facilities with capacities of 150,000 tons per year and 220,000 tons per year; a sulfur recovery unit with a capacity of 50,000 tons per year; acid water stripping units with capacities of 60 tons per hour, 120 tons per hour, and 150 tons per hour; solvent regeneration units with capacities of 130 tons per hour, 200 tons per hour, and 300 tons per hour; a 20,000 Nm3/h dry gas hydrogen production unit; an 80,000 Nm3/h natural gas hydrogen production unit; an 80,000 Nm3/h hydrogen production unit; a 10,000 Nm3/h air separation hydrogen production unit; and a 3,000 Nm3/h PSA hydrogen production unit. The main products include heavy traffic asphalt, diesel, gasoline, naphtha, etc. The existing facility has obtained a wastewater discharge permit (permit number: 911309837825909566001P), valid from April 1, 2025, to March 31, 2030. All existing projects have implemented comprehensive treatment measures; exhaust gases, wastewater, and noise are discharged in compliance with standards, and solid waste is properly disposed of. Construction content: Utilize the mixed xylene resources available throughout the plant to produce p-xylene products. The facility consists of an adsorption separation unit, an isomerization unit, a xylene separation unit, as well as supporting utility systems, with a p-xylene production capacity of up to 2 million tons per year. The chemical new materials base project of Hebei Xinhai Holding Group has a total investment of 50 billion yuan and covers an area of 5,000 mu. The project is being constructed in two phases; the first phase commenced in November 2024, with completion and operation expected by 2027.
