Emission control

Local and global regulations concerning exhaust gas emissions have grown significantly tougher in recent years – and will likely become tougher still. Among those affecting the marine industry are regulations that limit emissions of nitrogen oxides (NOx), sulphur oxides (SOx) and particles.

Smart strategies for compliance

Vessel emissions can be abated without changing fuels. NOx formation, for example, can be limited by optimizing the combustion process through Exhaust Gas Recirculation (EGR). Alfa Laval has partnered with MAN to develop this technology in which Alfa Laval PureNOx Prime has a vital role.

Other emissions can be removed effectively after their formation, such as SOx which is a direct result of the fuel sulphur content. Using a scrubber like Alfa Laval PureSOx, vessels can meet limits in Emission Control Areas (ECAs) while continuing to use economical HFO.
