Target 2023 Target 2022 Performance 2022 Performance Indicator VOCs emission concentration (tons per thousand tons of production) • Volatile Organic Compounds (VOCs) Management In 2022, IRPC commenced the project of Enclosed Ground Flare (EGF) Installation to support effluent gas disposed from the factory. The EGF use an efficient burner design resulting in high combustion efficiency at 99.5% and its benefits are the reduction of black smoke and volatile organic compounds (VOCs), no thermal radiation, no visible flame and no odor/low noise. Overall, the progress of operations continues as planned as it was targeted to be completed in 2025. Preventive control is in place to prevent VOC emissions during maintenance work through the Green Turnaround concept, focused on assessing the risks of emissions from various activities in order to find appropriate measures to preclude the discharge volumes. Checking the equipment before turning on the system for maintenance, as well as surveillance measures around the factory fence is to confirm the practice results, including analyzing the significant factors in order to solve the actual cause of problems, which is a sustainable solution. Adopting guidelines in accordance with the Code of Practice (COP) in preventing VOCs emissions from three significant sources: storage tanks, incinerators and repair work into actual operations helps materialize VOCs problem solving. Air quality and odor management • NOx SOx TSP Management IRPC pays attention to air pollution control from chimneys. Firstly, the combustion factors are in control in order to achieve efficiency and reduce environmental impact, such as the combination of using fuels with less impact on the environment like Fuel gas. Secondly, the control of combustion conditions in the furnace is implemented in order to minimize air pollution, nitrogen oxides, sulfur oxides and total suspended particulates (NOx SOx TSP). Lastly, to diminish the level of Nitrogen oxides (NOx) emissions from chimney, it requires highly efficient technology of burner and Low NOx Burner is equipped. In addition to the combustion and fuel technology, in 2022, IRPC also has scheduled to do turnaround–a scheduled large-scale maintenance activity–which focused on maintaining the combustion efficiency of the equipment to remain operate accordingly as well as reducing the environmental impact. In area of monitoring, IRPC has collaborated and planned with third party consultants in measuring the air quality from the chimneys. The results of the measurement passed the control criteria of IRPC Industrial Zone and the standard value of pollutant emissions according to the Notification of the Ministry of Industry. This affirms the effectiveness of management of air pollution, nitrogen oxides, sulfur oxides, as well as total suspended particulates (SOx NOx TSP).
