Customer: Altera Infrastructure (formerly Teekay Offshore)
Volatile Organic Compounds (VOCs), except methane, are called NMVOCs that evaporate from crude oil due to their volatile characteristics. Storage, loading and unloading of oil in offshore platforms, storage ships (FSOs and FPSOs), onshore storage tanks and terminals, and on shuttle tankers, contribute significant emissions of NMVOCs. These VOCs are a mix of heavy hydrocarbons too volatile to be burnt in reciprocating engines. Altera Infrastructure, operating one of the world’s largest conventional tanker fleets, was looking for an efficient solution for use of the VOCs their shuttle tankers generated.
OPRA gas turbines recover 100% VOCs emissions from shuttle tankers, combusting surplus methane gas from the VOC plant of approx. 10 tons per loading. Emissions are reduced from 27,000 tons CO2 to 1,000 tons CO2 annually, while also producing electric power to the vessel grid. As OP16 Gas Turbines are fuel flexible they can operate on VOCs and natural gas simultaneously, ensuring continuous power in case of VOCs supply shortage.
