Facilities and Capacities

The complex occupies approximately 920-953 hectares and comprises an integrated refining and petrochemical facility with the following major capacities:

Refining Operations:

• 20 million tonnes per year (Mt/y) crude oil processing capacity (approximately 400,000 barrels per day)
• 300,000-tonne crude oil terminal
• Product terminal with berths ranging from 5,000 to 100,000 tonnes​

Petrochemical Production:

• 1.2 Mt/y ethylene plant (largest scale ethylene facility in China at startup)
• 2.6 Mt/y aromatics production, including para-xylene (p-xylene)
• 800,000 tonnes per year (t/y) styrene unit (world's largest single-train styrene plant)

The complex also includes supporting infrastructure such as long-distance pipelines, crude oil transshipment depots, railway facilities, and sewage treatment systems.

Technology Licensors

The complex utilizes advanced processing technologies from multiple international licensors:

Aromatics Complex:
Honeywell UOP provided technology for the 2.6 Mt/y aromatics complex, which is the world's largest single-train paraxylene unit. The aromatics block includes UOP's Sulfolane™, Isomar™, Tatoray™, and Parex™ (Light Desorbent version) processes, along with an Olefin Removal Process unit. Honeywell UOP also supplied heavy oil processing technology for the refinery.

Polypropylene:
W.R. Grace & Co. licensed its UNIPOL^® PP Process Technology for a 500,000 t/y polypropylene unit, which became the largest single-line UNIPOL unit in China. The unit produces homopolymer, random copolymer, and impact copolymer resins using Grace's 6^th generation non-phthalate CONSISTA^® catalysts.​

Refining Units:
LPEC (Luoyang Petrochemical Engineering Corporation) of Sinopec provided engineering design for several refining units, including a 3.6 Mt/y catalytic cracking unit, 4.2 Mt/y wax oil hydrotreating unit, 600,000 t/y alkylation unit, and 1.1 Mt/y additional processing capacity.
