Tooling up for the NOx regulations

摘要

Alfa Laval believes that one of those technologies, exhaust gas recirculation (EGR), is clearly on track and making rapid strides towards commercialisation, which is now being supported by further field testing. "The response [to Alfa Laval's own PureNOx system] is positive, especially since we now have streamlined and refined the PureNOx design, a smaller and less complex system with also a significantly lower cost," explains Kristina Effer, global business manager, exhaust gas water treatment, water treatment exhaust gas emissions, Alfa Laval. Effer goes on to say that licensees who build MAN B&W-branded engines in South Korea, Japan and China have already started to prepare for Tier Ⅲ compliant engines and adds that it will be the shipowners who decide what technology is applied, whether this is selective catalytic reduction (SCR) or EGR systems.
