Tenneco, Texas A&M Partner on Emissions Solution
Sea trials, training and scholarship program designed to educate students on clean air technologies. Tenneco, a global supplier of Clean Air aftertreatment technologies is helping engineering midshipmen at the Texas A&M Maritime Academy learn firsthand how advanced aftertreatment technology can help diesel engines meet new emissions regulations while efficiently and effectively powering the ships of the future. Midshipmen received hands-on experience this summer with Tenneco’s latest large engine selective catalytic reduction (SCR) diesel aftertreatment technology on the TS General Rudder, which is operated by the Maritime Academy. Midshipmen helped conduct field tests during their training cruises in the Gulf of Mexico to demonstrate how the system’s form…
New Large Engine SCR Systems Debuts at Workboat
Tenneco (NYSE: TEN) has announced that it has introduced a complete urea dosing control, fluid handling and catalyst solution for selective catalytic reduction (SCR) aftertreatment, enabling large engines to meet EPA Tier IV and IMO Tier III regulations. The company will showcase the complete system at the 2014 WorkBoat Show in New Orleans, Dec. 3-5, 2014 (Booth #2152). The system is designed specifically for high-horsepower engines in the marine, stationary and locomotive markets, providing precise and reliable delivery of liquid urea.
Two US Firms Collaborate on SCR Design
Tenneco and Cormetech sign agreement to design marine engine ultra-large diameter selective catalytic reduction (SCR) catalysts. The MARPOL Annex VI and EPA Tier IV regulations require an 80% reduction in NOx emissions, thus driving the need for engines to include aftertreatment strategies such as SCR. Tenneco’s SCR solution, incorporating the Cormetech catalyst, will be designed to help the marine industry comply with the new emission regulations. “Tenneco is an established leader in designing and developing diesel aftertreatment solutions, supplying commercial vehicle and engine manufacturers globally,” said Tim Jackson, Tenneco chief technology officer. “For more than 20 years, Cormetech has provided reliable state-of-the-art SCR catalyst for the reduction of NOx emissions.
EPA Adopts Emission Standards for New Diesel Engines
The Environmental Protection Agency (EPA) is adopting emission standards for new marine diesel engines that will be installed on vessels flagged or registered in the United States. The near-term, Tier 1 standards in this rule are equivalent to the internationally negotiated emission limits for oxides of nitrogen (NOx). These standards will go into effect in 2004 and are based on readily available emission-control technology. We will also undertake another rulemaking in a few years to consider a second tier of more stringent standards. The Tier 1 standards apply to marine diesel engines manufactured January 1, 2004 or later if they will be installed on vessels flagged or registered in the United States1.
News: New Marine Diesel Regs Adopted by EPA
Last month the Environmental Protection Agency (EPA) announced that it is adopting emission standards for new marine diesel engines that will be installed on vessels flagged or registered in the U.S. The near-term, Tier 1 standards in this rule are equivalent to the internationally negotiated emission limits for oxides of nitrogen (NOx). These standards will go into effect in 2004 and are based on readily available emission-control technology.
