The Implementation of Cat® SCR Technology

As the commercial marine sector adapts to the stringent EPA Tier 4 and IMO III emissions standards, Caterpillar Marine is leading the way with innovative solutions designed to enhance performance while fully complying with regulations. Caterpillar’s holistic approach combines a fuel-efficiency-optimized engine with a Selective Catalytic Reduction (SCR) aftertreatment system. This solution is poised not only to significantly reduce NOx emissions but also to diminish customers’ owning and operating costs, offering exceptional value in environmental responsibility and economic savings.

Understanding SCR in Three Steps:

The SCR operation starts at the dosing cabinet, where the correct dose of compressed air [1A] and urea [1B] is mixed. This mixture is sourced from the onboard urea tank and then transferred [2A] to the SCR module.

Once in the SCR module, it is injected into the exhaust stream [2B]. Here in the SCR module [3], the water from the mixture evaporates, and the urea is transformed into NH3, or ammonia.

When the converted ammonia comes into contact with the SCR catalyst, a reduction in NOx emissions occurs. The final products of this environmentally-friendly process are carbon dioxide, nitrogen, water, and oxygen – underscoring the efficiency and eco-conscious design of the SCR system.
