CR Ocean Engineering has released a short animation of its Exhaust Gas Cleaning System (EGCS) to demonstrate its operation as an alternative to low-sulphur marine fuel.
The video shows operation of all three configurations of the scrubber: the open-loop mode, the closed-loop mode, and the hybrid mode that enables operation in both fresh and seawater for maximum flexibility.
The scrubbers also offer design flexibility. The bottom-up entry design and metallic construction of the scrubber allows exhaust gas to flow without requiring a bypass, even when running dry where scrubbing is not needed. The exhaust gas inlet and scrubber drainage are designed to eliminate a potential for water back flow to the engine. Wash water flows from the bottom of the scrubber to storage tanks which are installed at lower elevation levels to improve ship stability.
The water is continuously recycled back to the scrubber, with only a small stream going to a wash water cleaning system used to remove the collected sludge and making the stream able to be discharged or stored for later disposal.
The scrubbers can be fitted to a wide range of ships, including RoRos, ferries, cruise ships and container ships. They can be installed to both newbuilds and as a retrofit option with single engines or multi-streaming operations.
