Discharge Management of VOCs

VOCs mainly come from processes (discharge channels), storage tanks, loading operations, wastewater treatment area, and grease-water separation pond, waste gas burning tower, and equipment elements. In 2022, total production capacity was 31,192.7 thousand tons, and VOCs discharge per unit product decreased 4.65% compared with the previous year. In the future, we will increase air pollution reduction equipment (collection from storage tank to CFB or waste heat boiler), and continue to reduce VOCs discharge per unit product.
