Wärtsilä VOC recovery system

Reducing VOC emissions primarily benefits our environment and climate. But recovering the cargo vapor can also contribute to more sustainable use of energy and increased profitability for vessel and cargo owners. The environmental impact of VOC emissions is significant, as the emitted gas consists of a range of hydrocarbons – including methane. Methane is a powerful greenhouse gas with a global warming potential that is 28 times higher than CO2. The non-methane fractions of VOC, known as NMVOC with a GWP 4 times higher than CO2, react in the presence of sunlight with nitrous oxides and create a toxic ground-level ozone and smog layer which has detrimental environmental effects on vegetation and on human health – particularly on the eyes and lungs.
