On July 6, 2023, with the 400,000 tons/year ethylbenzene-styrene unit producing qualified products, all units of the Anqing Petrochemical Refinery Conversion Plant Structural Adjustment Project were successfully started up safely and environmentally friendly at one time.

The project is led by a 3 million tons/year heavy oil catalytic cracking unit. By increasing the production of light olefins and aromatic raw materials to produce high-value-added chemical products, it effectively enhances the adaptability and flexibility of the company's production structure to changes in demand, and explores a development path for domestic refining companies to cope with overcapacity and achieve transformation and upgrading.

Among them, the 3 million tons/year heavy oil catalytic cracking unit is the world's first RTC process heavy oil catalytic cracking unit, and the 400,000 tons/year ethylbenzene-styrene unit is currently the largest dry gas-based ethylbenzene unit in China.

The heavy oil catalytic cracking unit of Anqing Petrochemical has been started-up

The heavy oil catalytic cracking unit of Anqing Petrochemical has a total of three main fan units, namely two main units K101A/B and one backup fan unit K102. After the backup fan is successfully started and the two units have completed the relevant air tightness and other related processes, the K102 unit will be shut down, and the two main fan units K101A/B will enter the ignition furnace heating stage. It is expected that the overall start-up process will continue for more than 10 days.

Anqing will stop operating its 1.4mn t/yr fluid catalytic cracker (FCC) and 700,000 t/yr deep catalytic cracking unit, which are located near a residential area, for environmental reasons. The project will involve adding a new 3mn t/yr DCC that will enable the refinery to process crude with a higher sulphur content of 1.5pc.

Anqing currently produces 30,000 t/yr of polypropylene, 100,000 t/yr of ethylbenzene and styrene and 210,000 t/yr of acrylonitrile, among other products. It will scale up output of these products through the upgrading project.

Sinopec's Anqing refinery shifts towards petrochemicals

Work on the 11bn yuan ($1.5bn) project at Anqing in the central province of Anhui started in early May. A Yn6.6bn first phase aims to produce around 2mn t/yr of olefins and aromatics, including 150,000 t/yr of ethylene, 640,000 t/yr of propylene and 610,000 t/yr of aromatics products. Trial production is scheduled for late 2022. A second, Yn4.4bn phase will add another 650,000 t/yr of unspecified chemical output.

Refined product output will be cut by a third after the project is complete, with the gasoline yield rising at the expense of diesel. Anqing is also expanding its pipeline connections to replace fuel transportation by river. Sinopec opened an 88,000 b/d oil products pipeline linking Anqing to the cities of Hefei, Huainan, Bengbu and Fuyang in late 2016.

Anqing will stop operating its 1.4mn t/yr fluid catalytic cracker (FCC) and 700,000 t/yr deep catalytic cracking unit, which are located near a residential area, for environmental reasons. The project will involve adding a new 3mn t/yr DCC that will enable the refinery to process crude with a higher sulphur content of 1.5pc.
