The Sinopec Zhenhai Refinery in Ningbo, Zhejiang Province, stands as one of the largest and most efficient oil refining facilities in China and across Asia. Serving as the flagship plant for the state-owned Sinopec Group, the complex integrates massive crude oil processing capacities with an extensive ethylene cracking unit for petrochemical production. The facility is strategically positioned within the Ningbo-Zhoushan port area, allowing it to directly receive supertankers arriving from the Middle East. Over recent decades, the site has undergone continuous expansion to meet the surging domestic demand for fuels and chemical raw materials. Zhenhai is often cited as a benchmark for integrated refining and chemical parks, where by-products are immediately converted into higher-value materials on-site. It employs state-of-the-art environmental technologies for wastewater treatment and emission monitoring as core parts of its operations. The refinery plays a vital role in the economic growth of the Yangtze River Delta, supplying downstream industries with essential plastics and synthetic fibers. Through persistent innovation in catalyst technology and process engineering, it maintains a top-tier position in global industry rankings. The plant remains a critical asset in China's national strategy for energy supply security.
