Sinopec Chemical

China is the world's largest producer of polyvinyl chloride (PVC). The dominant route in China is calcium carbide acetylene method: limestone plus coke yields calcium carbide, which reacts with water to acetylene, then HCl addition to vinyl chloride. Energy intensive, but coal-feedstock dependent.

Sinopec's 2023 ethylene output hit 14.5 million tonnes, China's largest capacity. Our Gulei base in Fujian hosts a 1.5 Mt/a ethylene plant supplying polyolefins and styrene-butadiene rubber. Refining-chemical integration captures every carbon fraction.
