Thai LNG Terminal To Recover Waste Heat

A contract for heat recovery at the PTT’s Map Ta Phut LNG import terminal in Thailand has been awarded to a Italian-US partnership.

Italy’s Exergy said May 14 that together with major US contractor Baker Hughes GE it had been awarded the contract by Samsung Engineering, the South Korean EPC contractor for the terminal.

The contract is for engineering, design and construction of a 5 MWe organic rankine cycle (ORC) unit that will recover waste heat from gas turbines at the Map Ta Phut LNG terminal. The ORC is scheduled to  start commercial operation in 1H2019.

Exergy’s’s ORC solution will recover exhaust heat, generated downstream from two gas turbines installed in the LNG plant, and generate 5 MWe of electricity "performing an essential role for clean power production from the regasification process. The Italian firm's head of sales Luca Xodo said: "The application of our technology in the midstream and downstream sectors of the oil & gas industry will be a primary focus of Exergy strategy in the near future, as we have seen outstanding growth of the demand in this sector in the recent years."

PTT operates the Map Ta Phut LNG at Rayong, which commissioned in 2011 with capacity of 5mn mt/yr. In 2017 the terminal's capacity was expanded to 10mn mt/yr. The company is building the second terminal at a nearly location which will have a capacity of 5mn mt/yr.
