Emission Control Technologies DPF and DOC for Reducing Diesel Particulate

Diesel Particulate Matter (PM) Vapour Phase Hydrocarbons Solids (SOL) Solid Carbon Spheres (0. 010. 08 mm dia) combine with Adsorbed Hydrocarbons to make Particle Agglomerates (0. 05 -1. 0 mm dia) Soluble Organic Fraction (SOF) / Particle Phase Hydrocarbons Adsorbed Hydrocarbons Liquid Condensed Hydrocarbon Particles Sulphate with Hydration Courtesy of SAE® Sulphate (SO 4)

DPF (Diesel Particutale Filter) DOC (Diesel Oxidation Catalyst) DOC CRT® (Continuosly Regenerating technology) • DPF – >85% PM reduction • DOC – Typical 25% PM reduction • ULSD required

DPF Applications Off Road Equipment Trucks CRT® Products Stationary Engines Locomotives Buses

Emission Control Technologies Methane Oxidation Catalyst

Methane Oxidation Catalysts • Development of new catalysts required to improve low temperature activity and extend catalyst life

Emission Control Technologies SOx Scrubbing System

Scrubber System Retrofit • Achieves >97% reduction in SO 2 • Sea water intake and discharge • Fuel cost savings STEAM COIL FOR PLUME SUPPRESSION SEAWATER DISCHARGE 11, 349 kw DIESEL ENGINE
