TENNECO SHOWCASES FULL RANGE OF EMISSION CONTROL SOLUTIONS FOR MARINE APPLICATIONS AT 2015 INTERNATIONAL WORKBOAT SHOW
Lake Forest, Illinois, December 1, 2015 –Tenneco (NYSE: TEN), a leading global supplier of Clean Air aftertreatment technologies, is highlighting its full suite of production-ready emission control solutions for marine applications at the 2015 International WorkBoat Show, December 1-3 in New Orleans (Booth 1117). The company will display its high horsepower selective catalytic reduction (SCR) aftertreatment system, which is designed for U.S. EPA Tier 4 and IMO Tier III emissions requirements.
Tenneco’s SCR aftertreatment system features a complete dosing control solution for marine engine applications up to 7,500 kW or 10,000 hp. The system is designed to enable propulsion and auxiliary engines to meet U.S. EPA Tier 4 and IMO Tier III NOx reduction requirements and provides precise and reliable delivery of liquid urea via a proprietary, high-performance injector design, a precision mechatronic fluid delivery pump and customizable remote monitoring and controls. The system also features an integrated soot blower option, which increases the effectiveness of NOx reduction and overall catalyst performance when high sulphur fuels are used or engines operate at low exhaust temperature levels.
Tenneco will also showcase the versatility of its modular system, with catalyst architectures incorporating round and square designs, and a powerful urea delivery system capable of managing total fluid line lengths of 120 meters, providing engine manufactures and ship builders with outstanding flexibility in system design.
“Tenneco’s leadership in aftertreatment solutions enables us to deliver proven technology designed to meet maritime emissions regulations around the world,” said Jay Kedia, Tenneco managing director, large engine. “With our regulatory expertise and global engineering and manufacturing capabilities, Tenneco is well-positioned to support our marine customers with advanced solutions that provide optimal NOx reduction.”
SCR System Features
The SCR system’s modular design enables seamless integration for a broad range of engine sizes and works with electrically or mechanically controlled engines. It has been validated for durability and all components are easy to maintain and service without the need for special tools.
The fluid delivery system with dosing control software is capable of managing multiple injection points and sensors. The system can support urea flows up to 120 meters, which enables a wide array of installation options. Airless urea injection provides high dosing accuracy and consistency without the need for dedicated compressed air.
The system’s unique Human Machine Interface (HMI) can be accessed on the front of the fluid delivery box or remotely via a touch screen tablet. It features an easy-to-use interface to monitor and control all system parameters including but not limited to NOx reduction performance and urea concentration levels in real time. Onboard diagnostics are capable of monitoring more than 100 parameters including urea leakage, sensor faults and backpressure.
Tenneco has conducted a series of sea trials over the past 12 months to demonstrate how the system’s form, fit, function and performance capabilities can be easily integrated into a vessel’s engine and control architecture. Last summer, the SCR system was installed on the TS General Rudder, a vessel operated by the Maritime Academy in partnership with Texas A&M University, for testing in the Gulf of Mexico. The system was installed on a 33-year old 800 horsepower, Tier 0 engine. While running the engine through multiple duty cycles during real time operation of the vessel, emission results collected using telematics demonstrated NOx reduction levels that kept the General Rudder compliant with U.S. EPA Tier 4 marine emission requirements under all operational conditions.
Field tests were also conducted in 2014 on a 224 ft. Great Lakes training vessel with a similar engine. In a series of validation tests, including the ISO 8178 E2 cycle, an engine outfitted with Tenneco’s aftertreatment system met all criteria for IMO Tier III including NOx and SOx.
Tenneco’s high horsepower SCR system is designed to meet the requirements of major maritime classification societies including ABS, CCS, DNV GL, KR and Class NK. Tenneco has been awarded product design classification from ABS and approved in principle classification from DNV GL.
