Flexible Feedstock and Highly Competitive Cost Structure

Flexible Feedstock and By-Product Enhancement

PTTGC's refinery business is able to process a variety of crude oil at a competitive cost due to high complexity

Availability of feedstock along the whole carbon chain enhances the value of PTTGC by offering increased flexibility for better optimization, resulting in further cost advantages – Olefins can be produced from naphtha or ethane directly

from the Gulf of Thailand – Aromatics can be produced from condensate or reformate

from the Refinery Value enhancement from by-product exchange among Olefins,

Aromatics and Refinery units for upgrading at the other unit highlights operational integration and efficiency, for instance – Refinery unit can use condensate residue and hydrogen

from Aromatics unit – Aromatics unit can use pygas from Olefins unit – Olefins unit can use offgas and C3, C4 from Refinery and

Aromatics units, respectively
