PTT is the largest gas separation operator in Thailand. We run six gas separation plants to separate various hydrocarbons from the natural gas which in turn maximizes value of the gas from the Gulf of Thailand. The Gas Separation Plant Units 1-3, 5 and 6 are located in Tambon (Sub-district) Mab Ta Phut, Amphur (District) Mueng, Rayong Province and the fourth Unit in Amphur Khanom, Nakhon Sri Thammarat Province.
Presently, PTT’s gas separation plants have a nameplate capacity of 2,660 million cubic feet per day (MMSCFD). The first Unit’s capacity is 350 MMSCFD; the Second and the Third Units (including increment from the ethane separation plant) have a capacity of 750 MMSCFD. As for the Fourth Unit, its capacity is 230 MMSCFD, while the Fifth and the Sixth Units have a capacity of 530 and 800 MMSCFD, respectively. The last plant, the Sixth Unit has a capacity to process 800 MMSCFD. Due to continuous effort to improve efficiency of the gas separation plants, a combined processing capacity of every unit in 2012 is 2,740 MMSCFD.
