Olefins is an organic chemical compound comprised of hydrocarbons, especially ethylene and propylene. Made from ethane, propane, naphtha, and gasoline that are composed in natural gas and crude oil, olefins are ideal for use in the apparel, automotive, and home furnishings industries.

PTT Global Chemical’s (PTTGC’s) core business is manufacturing and distributing olefins products to our downstream petrochemical plants and other industrial plants. The company's olefins plants use natural gas and naphtha as feedstock, allowing for flexibility in raw material use.

PTTGC’s Group Performance Center - Olefins operates three plants with annual production of 2,890,000 tons. This includes ethylene production of 2,366,000 tons per year and propylene production of 524,000 tons per year.

PTTGC’s olefins plants have the capacity to provide by-products including pyrolysis gasoline, which is used to produce aromatics goods, as well as Mixed C4, tail gas, cracker bottom, and hydrogen. The synergy of our refining facility and aromatics plants adds to the value of these by-products.

Our Butadiene and Butene-1 Units add value to Mixed C4 by-products with butadiene production of 75,000 tons and butene-1 production of 25,000 tons annually. Mixed C4 byproducts yield higher value by delivering butadiene and butene-1 solutions. All of these products can be further developed and used as a substrate for a diverse range of downstream industries such as automotive, packaging and electronic parts.
