Offshore gas flaring is increasingly recognised as a major environmental problem, causing 400 million tons of CO2 in annual emissions, not to mention the valuable resources that go to waste. When considering the vented BOGs and VOCs from the marine industry, the overall GHG effect becomes even stronger.
With the Wärtsilä GasReformer, this undesired gas can be reliably and efficiently utilised by Wärtsilä dual-fuel engines. When utilising associated gas or recovered BOG from tankers or gas carriers as a reliable source of energy, the operator can achieve self-sufficiency in terms of energy supply and thus the need for fuel bunkering or BOG reliquefactions, both costly operations, decreases. With a Wärtsilä 10 MW GasReformer combined with a DF engine, the operator can reduce the need for bunkered fuel oil by 39 TPD and reduce flaring by more than 1.1 MMSCFD which equals to >100 TPD CO2eq. Where VOCs are usually vented, GHG emissions are reduced by 10.6 TPD CO2eq per ton recovered VOC.
