Emission Improvement Project (EIP)
  • Oxide of Sulphur (SOx) is the significant pollution of petroleum refineries, which generates strong ordor pertaining to major complaints from the surrounding communities when the astmosphere around the refinery is not appropreate for gas dispersion. 
  • Emission Improvement Project (EIP) has been installed in 2015 in order to improve the quality of air for the surrounding communities and our employees working in the area. As a part of the Energy Master Plan, Thaioil has invested in advanced refinery solutions for cleaner and higher quality oil production and the product line.  With such solutions, Thaioil is able to refine poor quality crude oil to produce product that meets the standard of Euro IV; hence reducing SOx emissions from refinery production beyond the requirements of the laws and regulations. This project also response to UN Sustainable Development Goal 3: Improvement in health and well-being.
  • This allows Thaioil to have the flexibility in purchasing poor quality crude oil which leads to cost saving and to minimize risk of crude oil shortage. With EIP, all production units now produce products with Euro IV grade and generate   revenue of liquid sulphur capture from the emission to the company. The communities and our employees benefit from this business program through the 60% SOx emission reductions both from the production process as well as from tail pipe emissions. As the result, they now have better quality of health and well-being from cleaner air.
  • Performance of this project are measured as quantity of SOx emitted from our operation and community perceptions (e.g. number of odor complaints and community satisfaction score). The value on health of people in our society is also tracked by the commodity medicines program which conducting the community health survey to prepare community health profiles by  means of Family and Community Assessment Program (FAP) since 2011.
  • Not only the social and environmental impacts near the refinery are measured, but the social and environmental externalities outside refinery are valuated by conducting the study on life cycle assessment. SOx can evaporate and cause acidic rain which could impact other areas away from the site of emission. Acidic rain damages vegetation and wildlife, and pollutes water bodies. In addition, EIP benefits on better air quality contributed by vehicles consumed our Euro IV product.
