Offshore gas flaring is increasingly recognised as a major environmental problem, causes 400 million tons of CO2 in annual emissions, not to mention the valuable resources that go to waste.
The associated gas, separated from crude oil, is traditionally flared and not utilised because it varies in composition, and contains a lot of heavier hydrocarbons. Generally it is considered as waste or an unreliable source of energy.
With the Wärtsilä GasReformer, this undesired gas can be reliably and efficiently utilised by Wärtsilä dual-fuel engines. When utilising associated gas or recovered VOCs from tankers as a reliable source of energy, the operator can achieve self-sufficiency in terms of energy supply and thus the need for fuel bunkering, a costly operation in offshore locations, decreases. With a Wärtsilä 10 MW APG GasReformer combined with a DF engine, the operator can reduce the need for bunkered fuel oil by around 35–39 tons per day and the system produces electricity with an overall efficiency of up to 44.5%.
