Exhaust Gas recirculation (EGR) is used to reduce NOx as per the Tier III requirements when use with compliant fuel as LSFO, VLSFO or LNG. The EGR process will generate a portion of bleed off water that must be treated to < 15 PPM which is also the requirement for bilge water. By combining the two treatment systems, the Capital Expenditures will be significantly reduced without any negative impact on performance. Additionally, there will also be a welcomed reduction in Operating Expenditures as maintenance, spare parts and training are needed only for one unit.
The system is based on Marinfloc’s well-known flocculation technology with thousands of references worldwide. The Whitebox® is included as standard to segregate the waste streams, to eliminate cross contamination and record all activities. Moreover, the Whitebox® fulfils the EXXON requirements and is Marinfloc’s recommendation on all US calling vessels.
Many shipowners are reluctant to go for EGR solutions due to the extra treatment unit that has to be installed onboard the vessel. The Marinfloc system not only removes one unit but also adds one of the markets most reputable high performance bilge separator that produces effluent values as standard on <5ppm.
By adopting the Marinfloc system you will take advantage of all the benefits with EGR without adding an extra treatment unit.
When using the Marinfloc system in combination with MAN-ES ECO EGR even lower Opertating Expenditures can be gained.
