Emission Reduction Programs
GC has conducted many projects relating to air pollution efficiency in 2021 to control air pollution in operating sites, offices, and surrounding areas within the standards stipulated by laws, regulations, and international practices. We have also implemented innovation and technology to reduce air pollution emissions through cooperation with government agencies and petrochemical industry operators to promote the practices to reach at maximum efficiency. Highlight projects in 2021 include:
GC has controlled NOx and SOx emissions from production process to be lower than the limitation that prescribed in the Environmental Impact Assessment (EIA) Report and Thai regulations. GC has developed programs to monitor NOx and SOx emissions in order to reduce impact to environment such as
- Using Continuous Emissions Monitoring System (CEMS) and periodically monitoring air emission quality by the certified external laboratories.
- Improving Gas Turbines and Low NOx Burners to reduce the NOx pollution emitted from its source.
- Adopting a policy for selecting raw materials and fuels, which have less impact to health and environment.
- Using low sulfur fuel oil and feedstock to reduce SOx emissions from combustion.
- Minimizing amount of fuel oil consumption to limit SOx emissions.
In 2021, highlights projects relating to improvement on control efficiency of air pollution include:
Implementation of Code of Practice (CoP) to Reduce Emissions of 1,3-Butadiene
GC has implemented the Code of Practice, or CoP, in the turnaround process to regulate 1,3-Butadiene emissions into the atmosphere arising from the turnaround activities to the minimum and complied with legal standards. In this regard, GC has comprehensively managed waste and such vapors by, for example, covering the flange when dismantling a device, installing a hazardous substance detection system and a state-of-the-art exhaust screening system, carefully and effectively covering VOCs waste during transportation for disposal, eliminating waste in accordance with the 5Rs principle and adhering to the 5S principle in performing duties.
The continuous implementation of diverse air quality control projects has led to a declining trend in air pollution as well as zero complaints regarding air pollution from surrounding communities.
The Termination of Chloro Fluoro Carbon: CFC
As GC’s commitment in reducing the impact of climate change, GC has planned to terminate the use of chemical that destroys the Earth’s atmosphere such that CFC by 2030 and shift to using non-CFC cooling agents instead. As a result, in 2021, GC has shifted to use a non-CFC cooling agent in the AC system in the whole company’s facilities and factories by 3,584 units or 36% of the total number of AC within GC’s properties.
