CiTECH have been awarded the order from Unocal/Thai Oils for a total of seven CiBAS WHRU for the Arthit Central Processing Platform to provide heat to the on-board Gas Dehydration and Processing Systems.

The CiBAS C100 units are designed to be cold casing and run flooded, the units are specified to recoup at a combined flow rate of 280,000 kg/hr a total thermal duty of 15,920 kW through a Hot Oil system recovering heat from two RB 211 Gas Turbines.

The CiBAS C45 units are designed to be cold casing and run dry, the units are specified to recoup at a combined flow rate of 120,000 kg/hr a total thermal duty of 6,850 kW through a Hot Oil system recovering heat from three Solar Taurus 60 Gas Turbines.

The CiBAS C30 units are designed to be cold casing and run dry, the units are specified to recoup at a combined flow rate of 87,000 kg/hr a total thermal duty of 5,000 kW through a Hot Oil system recovering heat from two Solar Mars 100 Gas Turbines.

The Arthit Central Processing Platform is the biggest offshore platform in Southeast Asia, weighing 17,000t. It was constructed in Bantam Island, Indonesia, and features gas and condensate processing facilities. On average, production from the field ranges from 280 to 330 million standard ft³/day of natural gas and 13,000 to 14,000 barrels a day of condensate.

The produced gas is exported to the Erawan Riser Platform through a 200km long, 42in diameter subsea pipeline. The condensate is exported to the Bongkot FSO2 through a 30km long subsea pipeline, 8in diameter.
