Most cargo ships entering ports depend on electricity they generate themselves with auxiliary diesel engines on-board instead of shore-power because they can control their own equipment and do not have to rely on the numerous types of connections required for shore-power. It is estimated that this SINOx® SCR System will reduce nitrogen oxides (NOx) at the Port of Long Beach (POLB) by 100 tons each year while in service for Mitsubishi Cement Corporation. The SINOx® SCR System will be shipping from Argillon Americas in August 2007 to the Port of Long Beach (POLB) for installation and commissioning this fall.
The capture system that covers the exhaust outlet from the ships auxiliary engines is one of the unique components of this SINOx® SCR System. The SCR, continuous emissions monitoring (CEM), motor control center (MCC) and other related hardware is mounted on a remote-controlled platform that can move forwards/backwards and side to side. This mobile system allows the SCR system and capture hood to move into the optimum position for any size ship and different exhaust configurations coming into the port. See drawing below for more clarification of SCR system.
