Overview
Changxing Island Hengli Petrochemical power station is a 720 MW coal-fired power plant in Dalian, China. It is operated by Changxing Island Hengli Petrochemical (Dalian) Co. and serves the local industrial grid.
Changxing Island Hengli Petrochemical power station is a coal-fired power plant located on Changxing Island in Dalian, Liaoning Province, China. With a capacity of 720 MW, it is a medium-to-large scale facility within China's extensive coal power fleet. The plant is owned and operated by Changxing Island Hengli Petrochemical (Dalian) Co., a subsidiary of the Hengli Group, and primarily supports the energy needs of the petrochemical complex on the island. As a coal-fired plant, it operates under China's national emission standards for thermal power plants, which include limits on SO2, NOx, and particulate matter. The plant likely uses conventional pulverized coal combustion technology, typical for facilities of its age and scale. China has been progressively tightening emission regulations, and newer plants are required to install flue-gas desulfurization (FGD), selective catalytic reduction (SCR), and electrostatic precipitators (ESP) to meet these standards. The plant's location on Changxing Island, a major petrochemical and industrial hub, underscores its role in providing reliable baseload power to energy-intensive industries. Its proximity to the Bohai Sea also raises considerations for water use and marine emissions. As China transitions toward cleaner energy, coal plants like this one face increasing pressure to improve efficiency and reduce environmental impact, though they remain critical for grid stability in industrial regions.
Environmental context
The plant's coal combustion releases CO2, SO2, NOx, and particulate matter, contributing to local and regional air quality concerns. Its location on Changxing Island, near populated areas and the Bohai Sea, necessitates strict adherence to China's emission standards. The 720 MW capacity implies significant fuel consumption and waste generation, including coal ash. Environmental management likely includes FGD, SCR, and ESP systems to mitigate pollutants, though carbon emissions remain a challenge.
