Product leaflet: PureVent - Centrifugal oil mist separator for cleaning crankcase gas - Alfa Laval - #1

Text version of the page

Reducing emissions from internal combustion engines has been a major environmental concern. Up to now, most of the focus has been on exhaust gases. However, crankcase gas has now come into focus as an area where further emission reductions can, and should, be made. Application PureVent is a compact centrifugal oil mist separator that, when connected to medium-speed diesel engines, removes 98–99.9% of oil from crankcase gases. Recovered oil can then be re-circulated to the oil sump and used again for engine lubrication. Two installation options are available: • Open design for diesel engines releasing oil-free crankcase gas directly into the atmosphere. • Closed design for gas engines re-circulating clean gas to the turbocharger, thereby reducing the atmospheric emissions further and eliminating turbocharger fouling. Benefits • High separation efficiency. Provides 98–99.9% separation efficiency at 40–150 m3/h. • Stable pressure conditions. No pressure drops or clogging associated with filter cleaning solutions. The continuous outflow at constant flow stabilizes pressure in the crankcase. • Recovered oil can be re-circulated to oil sump. • No hazardous waste. Elimination of oily filter disposal costs. • Long maintenance intervals. Two-year service intervals eliminate the frequent maintenance requirements associated with filter replacement.
