PTT Global Chemical (PTTGC), in its management discussion analysis for 2019, said a new olefins plant being built at its complex in Map Ta Phut, Rayong, Thailand, is expected to start commercial operation this year. The USD 985-million projects included a 500 kta ethylene plant, based on CB&I's technology, and a 250 kta propylene unit. It will increase the company's total nameplate olefins capacity to 3.7-mta from nearly 3-mta currently. In 2018, Samsung Engineering awarded a contract to CB&I for the license and basic engineering of the ethylene facility and a pyrolysis gasoline hydrogenation unit. The contract also included detailed engineering and material supply of Short Resistance Time pyrolysis heaters.
