PrimeServ Retrofits SCR System
MAN Diesel's after-sales group, PrimeServ announced that it has retrofitted a selective catalytic reduction (SCR) system aboard a Norwegian tanker. This retrofit represents an important step into the exhaust gas aftertreatment market, as well as this retrofit segment.
In spring 2009, Knutsen OAS Shipping, Norway approached MAN Diesel PrimeServ in Augsburg, Germany to provide a technical solution for the reduction of NOx emissions aboard its product tanker, M/V Liv Knutsen. MAN Diesel was awarded the contract for the supply and commission of an SCR catalyst to operate downstream of the MAN 6L48/60B main engine.
In the case of the Liv Knutsen, MAN Diesel implemented an exhaust gas temperature control using a charge-air blow-off flap. The operation map of the control system reflects the exhaust gas temperature and sulfur content of the fuel currently in use. In this, optimal SCR operation was achieved at all engine loads.
Governmental authorities, especially in Scandinavian countries, provide incentives to marine operators that implement emission-reduction technologies. The Norwegian NOx fund subsidizes investment in NOx-reduction measures on vessels sailing in Norwegian waters.
