Gas Recirculation Technology

  • Clean Marine was selected by Hyundai Heavy Industries to supply exhaust gas cleaning systems (EGCS) for a Very Large Gas Carrier (VLGC) being built for Dorian LPG Ltd. Clean Marine has developed an EGCS based on the Advanced Vortex Chamber technology that provides unique particulate matter trapping efficiency. The system’s integrated fan and gas recirculation technology also allows the one EGCS unit to simultaneously serve several combustion units. The system supplied to Dorian LPG is a hybrid system that allows the vessel to operate seamlessly in all types of water (including low alkaline and saline water) without loss of efficiency.
