Sinochem Quanzhou Petrochemical Project is planned and constructed with the goal of "first-class in the world and leading in China". In terms of process flow, the project adopts the scheme of "large residue hydrogenation+small delayed coking", which has strong processing capacity for heavy and inferior crude oil, and the proportion of hydrogenation capacity to primary crude oil processing capacity reaches the highest level in China. Crude oil resources are deeply and comprehensively utilized, and the output of light oil is at the leading level in the industry. The key core equipment of the project has introduced mature technologies with international advanced level. The environmental protection, safety and occupational health of the project are designed according to high international and domestic standards, and the most advanced refinery wastewater treatment technology in the world is adopted. The investment in environmental protection, including product refining, desulfurization and other devices, exceeds 2 billion yuan.
