In recent years, the International Maritime Organization (IMO), Europe, and the United States
and other countries have set up different emission control areas (ECA) for ship exhaust …

In the present work, the contemporary exhaust gas treatment systems (EGTS) used for SOx,
PM, and NOx emission mitigation from shipping are reviewed. Specifically, after-treatment …

The high-pressure SCR system is suitable for low-speed marine engines that burn high-
sulfur fuel, but it will cause the increase of the exhaust back pressure of main engine, which …

The problem of urea crystallization in selective catalytic reduction (SCR) systems has been a
concern for a long time, especially in vehicle engine after-treatment. Compared with the …

The salmon farming industry has recently shifted to larger culture tanks with greater water
flows to optimize the land-based production, but tanks approaching 1000 m 3 in volume …

Owing to the increasing stringent regulations on diesel exhaust emissions, the performance
requirements of exhaust gas treatment devices are becoming increasingly higher. However …

Selective catalytic reduction (SCR) systems are among the most effective methods used to
reduce NO X emissions in internal combustion engines. SCR system performance is directly …

For marine diesel engines, the selective catalytic reduction (SCR) system can be tailored to
ensure high nitrogen oxides (NO x) reduction performance, low ammonia (NH 3) slip, and …

In order to design a compact urea selective catalytic reduction system, numerical simulation
was conducted by computational fluid dynamics tool. A swirl type static mixer and a mixing …

The continuous increase in the number of stringent exhaust emission legislations of marine
Diesel engines had led to a decrease in NOx emissions at the required level. Selective …
