Marine Exhaust Solutions (Canada), has developed a solution to an environmental problem that has been plaguing the international industry. The EcoSilencer® is a unique product that utilizes advances in seawater scrubbing to achieve dramatic reductions in SO2 emissions. It replaces the silencer in engine exhaust stack helping to reduce emissions, remove soot, reduce airborne noise and noxious fumes, which would otherwise be released into the atmosphere. The EcoSilencer® is a result of six years of development work and testing, and is now available for both the commercial shipping industry and the super yachts.

Recently completed trials have proven EcoSilencer® seawater scrubbing system saves millions of dollars in potential low sulphur fuel cost premiums, and provides superior reduction rates for SO2 removal over switching to low sulphur residual fuel. In fact, system trials have been so successful, that the company is prepared to offer a Guarantee of Performance with every installation. Depending on vessel’s engine configuration, the EcoSilencer® will reduce SO2 exhaust emissions by up to 90 % - with a performance guarantee that it will allow to burn the maximum 4.5% sulphur fuel and still surpass the regulated reduction to 1.5% sulphur fuel.

The EcoSilencer® works by using its patented design to mix the hot exhaust gas in a turbulent cascade with seawater. This new technology ensures that surface area for contact between gas and water is high, and sufficient time for absorption of pollutants is provided. The acidic gasses, and particulate removed from the exhaust gas are passed through a water treatment system, which is designed to filter wastes on a continuous basis, and to provide outlet water that is environmentally safe.

EcoSilencers are suitable for installation on any engine size from 100 kW to 100,000 kW, easily handling changing engine load and work with any inlet seawater conditions and engine loading. Equipment operates over a range of insertion backpressure less than 100 mm H2O.
