In this publication the wash water subsystem features of an exhaust gas recirculation (EGR) system of marine diesel engine are considered. In regard with the safety of the operation, a procedure for handling the wash water system of the EGR is proposed. The chemical reactions between the flue gas and the process water are observed. The wash water system components and their specifics related to the chemical reactivity are presented. The problems with the water impurities, pH value and the operation of the EGR system are highlighted. The engineering crew special precautions on safety on using caustic soda on board is considered. Recommendations are proposed.
