Our Businesses

Five groups,
one molecule.

From a 280,000 bbl/day refinery to bio and specialty chemicals, GC's businesses interlock into a single, margin-capturing value chain of ~14.34 million tons per year.

BUSINESS GROUP 01

Refinery

GC operates a world-scale refinery at Map Ta Phut processing crude oil and condensate into transport fuels and the naphtha and aromatics precursors that feed the rest of the chain. In 2025 it began commissioning Sustainable Aviation Fuel from existing units.
