GC One Report 2023 [EN]

Aromatics GC produces and distributes aromatics products, namely benzene, toluene, paraxylene, orthoxylene, mixed xylene, and cyclohexane. The majority of these products are used as feedstock in various industrial processes domestically. Aside from these products, GC’s aromatics plants yield multiple by-products, including liquefied petroleum gas (LPG), light naphtha, heavy aromatics, and condensate residue. LPG and light naphtha are used as feedstock in GC’s olefins plants, while heavy aromatics and condensate residue are used as feedstock in the refinery to produce jet fuel, diesel, and fuel oil. GC currently operates two aromatics plants with a combined capacity of 2,419 thousand tons per year. The table below details the nameplate capacity of each product: Policy and Marketing In sourcing feedstock for its aromatics plants, GC’s strategy focuses primarily on procuring domestic condensates, which are the most cost-effective, as well as condensates from new sources in the global market as alternatives in order to reduce production costs, such as from Indonesia and New Zealand. As for its distribution strategies, GC sells its aromatics chiefly to domestic customers, with the majority located in the Map Ta Phut Industrial Estate, while also fostering cooperation within PTT Group to boost global exports and promote collaboration, such as shared sales and transportation. In 2023, approximately 77% of GC’s aromatic products were sold to domestic customers, most of whom were customers with long-term and short-term agreements, accounting for around a 64% market share of total domestic sales. The remaining 23% aromatic products were exported primarily to customers in Asia.
