Process of Petroleum Production from Crude Oil and Other Raw Materials

The Company’s refinery is located near Laem Chabang Port in Sriracha, Chonburi, which provides convenience in transportation whether by sea, train, truck, or through Thai Petroleum Pipeline’s multi-product pipeline. The company can, therefore, deliver its products to customers efficiently and at a reasonable cost.

Through the years, Thaioil has been improving its refining technologies to ensure that they meet international standards. To reflect our determination toward continuous improvement and to create product and service reliability among our customers, the ISO 9001: 9002 and ISO/IEC 17025 was brought in as a tool to be used in production management and petroleum product testing laboratories accreditation respectively. Both systems have been successfully accredited by the Management System Certification Institute (Thailand) since 1996.

There are 3 main units in Thailoil Refinery:

1. Crude Distillation Units:
Responsible for distilling different types of petroleum through separation at different temperatures
2. Upgrading Units:
Responsible for upgrading lower value products to higher value products by means of chemical reactions
3. Quality Improvement Units:
Responsible for improving the quality of the oil to meet the required standards, as well as the removal of contaminants
