Three-Way Catalysts for Talisman Energy

Natural gas compressor station in northern Alberta, Canada, powered by Waukesha 7042 GSI engines. Challenge The challenge was to meet emission targets for NOx, CO and non-methane hydrocarbons, for a variety of compressor engines with different exhaust configurations. Solution DCL supplied the catalyst housings in two basic configurations for this project. The first configuration was […]

Oxidation Catalysts for Btc Pipeline

Eighteen (18) compressors, powered by 7600 hp Wartsila engines. The compressors move oil from the Caspian Sea to the Mediterranean Sea in the Turkish portion of the Baku-Tbilissi-Ceyhan (BTC) pipeline. Challenge Engine-out emissions for this major pipeline project were to meet the World Bank standards. The design target called for an oxidation catalyst to reduce […]

Diesel Particulate Filter for John Deere Backhoe

Metro Transit Authority construction site, Manhattan, New York City. John Deere 710G backhoe. Challenge A diesel particulate filter was required to meet local standards for particulate reduction. It was also necessary that the emission control device be installed such that it would not obstruct the line-of-sight of the vehicle operator. Solution DCL custom designed a […]

Oxidation Catalysts for Co-generation Plant

Manuli Film, Naples, Italy, with three (3) Rolls Royce KVGS-18G2, lean burn, natural gas engines, each 3030 kW electrical. Thermal power is utilized both from exhaust gas and cooling water for plastic film production. Challenge Required to meet emission standard of 400 mg/Nm3 @ 5% O2 for carbon monoxide and 150 mg/Nm3 @ 5% O2 […]

Exhaust Purifier (Exhaust Scrubber)

Gardner Denver MK45H rock drill. Challenge A universal exhaust purifier was required that could easily be retrofitted into the vehicle exhaust pipe. Solution DCL supplied an exhaust purifier (exhaust scrubber) with connection cones to match the vehicle exhaust tube diameter. The unit was connected to the exhaust tube with standard muffler u-clamps. Quick-release clamps on the […]

Catalytic Muffler for Caterpillar Underground Mining

Caterpillar Underground Mining required a manufacturer to design, develop and supply a catalytic oxidation muffler for first fit installation in their extreme duty mining vehicles. Challenge The catalytic oxidation mufflers were expected to provide a combination of noise reduction, low levels of nitrogen dioxide and high removal efficiencies in carbon monoxide, hydrocarbons and soluble fraction […]

Catalytic Silencer for Meeting Rice Neshap Standards

A Mid-Western USA utility company was interested in retrofitting their diesel generators for compliance with the 2013 RICE NESHAP rule set by the United States EPA. These are the Reciprocating Internal Combustion Engine National Emission Standards for Hazardous Air Pollutants. Challenge The first engine for retrofit was a 3500 hp Fairbanks Morse, 2-cycle diesel. The […]
