ALFA LAVAL'S DOUBLE - CUTTING FUEL BILLS AND EMISSIONS

摘要

Representing a completely new concept is a product that Alfa Laval calls PureDry. This is a highly innovative high-speed separator with the capability to recover re-usable fuel from waste fuel oil. With a totally unconventional design, the separator recovers energy by recycling the heavy fuel oil fraction in the waste fuel oil tank, leaving only super-dry solids that can be landed as dry waste. The separator also incorporates what the company describes as 'a solids removal twist'! With high oil prices, bunker fuel oil accounting for around 60% of a vessel's operating costs, and increasingly stringent emission controls, a fuel strategy and ways to cut fuel bills are at the top of the agenda for most ship owners and operators today. It is now permissible to re-use waste fuel (MARPOL rule MEPC.l/Circ.642; 2008) and, according to Alfa Laval, for the first time there is a technically and economically efficient method of recovering waste fuel from fuel oil residues. With waste fuel recovery, WFR, a direct saving of up to 2% on fuel bills can be achieved with an investment that pays for itself and gives a healthy profit in the first year.
