The ethylene plant adopts Huanqiu's own ethylene process technology

On March 28, the substation of Guangdong Petrochemical project's 1.2 million tons/year ethylene plant was successfully powered at one time, becoming the first substation in the chemical zone to complete power supply.

As the first unit of the ethylene plant to be commissioned, the substation provided power guarantee for the smooth operation of the project's later single-unit commissioning, instrument calibration and other works. At the same time, as the power load dispatch centre of the plant, the substation will comprehensively monitor the safety of power operation in all areas of the plant, laying a solid foundation for the plant to be delivered.

Guangdong Petrochemical Project is the first super heavy and poor quality crude oil processing base in China. The project is located in Dananhai Petrochemical Industrial Zone, Jieyang City, covering an area of 953 hectares, with a construction scale of 20 million tonnes/year of oil refining + 2.6 million tonnes/year of aromatics + 1.2 million tonnes/year of ethylene.

The plant will also be equipped with a 300,000-ton crude oil terminal, a product terminal with a maximum berth of 100,000 tonnes, a long-distance pipeline, a crude oil transshipment depot, a railway and sewage treatment facilities.

The ethylene plant adopts Huanqiu's own ethylene process technology and is scheduled to be delivered on June 30, 2022.

According to the feedstock situation, the cracking furnace adopts a high steam production process. After the cracking gas is cooled by the traditional primary emergency cooler, it is also further cooled by the boiler feed water to cool down the cracking gas again.

In order to improve the coke removal cycle of the cracker, the radiating section stove pipe adopts an enhanced form of heat transfer to reduce the tendency of coking on the inner surface of the stove pipe, increasing the coke removal cycle by more than 30%.
