Introduction to Marine SCR System
The Marine Selective Catalytic Reduction (SCR) system is a crucial technology in the maritime industry. It is designed to reduce nitrogen oxide (NOₓ) emissions from marine diesel engines, which are a significant source of air pollution in ports and coastal areas. The SCR system works by injecting a reducing agent, usually urea, into the exhaust stream. The urea decomposes into ammonia, which then reacts with the NOₓ in the presence of a catalyst to convert them into harmless nitrogen and water. This technology helps ships comply with strict environmental regulations such as the International Maritime Organization's (IMO) Tier III standards, which set limits on NOₓ emissions in designated Emission Control Areas (ECAs).
