EGR Water Treatment

EGR Water Treatment

To reduce ship exhaust emissions, air emission regulations are driving the development of primary engine technologies and secondary exhaust emissions abatement systems. As a result, internal combustion engine manufacturers employ a variety of techniques and design characteristics to reduce NOX emissions. The reduction of NOX emissions at the source and the treatment of exhaust gas after combustion are the most common technologies utilized to meet the IMO Tier III standard. Exhaust gas recirculation (EGR) is a mechanism that redirects a portion of the exhaust gases (roughly 30–40%) to the engine’s intake side and then back into the cylinders. The recirculated exhaust gases reduce the amount of oxygen (O2) in the incoming air while increasing the amount of carbon dioxide (CO2). The peak combustion temperature drops dramatically as a result of the lower O2 content and higher specific heat from CO2 in the combustion air, resulting in lower NOX formation. To prevent corrosion of the combustion chamber components and the EGR system components, the recirculated exhaust gases must be cleaned and cooled before being re-introduced into the engine’s air inlet system. The degree of cleaning is determined by the sulphur content of the fuel used. The recirculated exhaust gas is cleaned and cooled using fresh water. To keep its ability to clean, cool, and neutralize exhaust gases, the water must be treated. The combustion process also produces condensate which must be drained from the EGR unit and treated.

Combined EGR and Bilge Water Treatment System CD-EGR

 
product options

Improving by removing. Cleaning both bilge and EGR bleed-off water with effective flocculation technology.

The CD EGR for EGR bleed-off and bilge water offers a streamlined approach to minimize equipment, installation, operational cost and CO2 footprint. While bilge water and EGR bleed-off water fall under different MARPOL Annexes, necessitating segregation, our system ensures they remain separate. This includes distinct holding tanks and sludge tanks. System segregation valves prevent any mixing, including the sludge generated during treatment. The class-approved automated switch-over sequence, managed by system automation, ensures seamless operation. rom the control panel, the operator can effortlessly choose the waste stream for treatment, the recorder or WhiteBox® (optional), oversee, record and segregate the vital discharge parameters, ensuring accurate record-keeping as mandated.

 

 

Process description: The CD-unit can take suction from either the EGR bleed-off tank or the Bilge water holding tank. Three three-way valves connected to a selector switch secure that the waste streams are never mixed. The EGR bleed-off water is collected in a bleed-off water drain tank of a cascade type. The tank should be equipped with heating coils to heat the bleed-off water to 40-55 °C, solid sensors that will detect solidification of soot. The system must have segregated sludge tanks as per the Marpol requirements. The wastewater is treated overboard through a WhiteBox® by the CD unit and all vital system data such as tank levels, valve positions, oil content, discharged volume etc. is recorded and logged in the WhiteBox® recorder.

EGR NOx water treatment system – WTS For MAN-ES EGR

 
product options

Marinfloc introduces the WTS, engineered for seamless integration with MAN-ES EGR system. Building on two decades of industry experience, we utilize the proven Marinfloc flocculation process to ensure that the WTS not only meets but exceeds operational expectations. Crafted from robust stainless steel, it stands as a testament to durability and precision. To further empower ship crews, we’ve embedded intuitive digital functionalities for streamlined documentation. And for those navigating with MAN-ES engines, the WTS offers the added versatility of doubling as an efficient bilge water separator. A blend of innovation, reliability, and performance – that’s the Marinfloc promise.

MAN-ES EGR Technology: MAN Energy Solutions’ Exhaust Gas Recirculation (EGR) is a proven method to reduce NOx emissions. By reintroducing a portion of the exhaust gas back into the engine, it ensures vessels remain compliant with environmental regulations.

WTS Integration Options with MAN-ES EGR:

1. Standalone EGR Bleed-off Water Treatment: Specifically designed to treat the bleed-off water from the EGR system, ensuring optimal water quality and regulatory compliance.

2. Combined EGR and Bilge Water Treatment (WTS–>CD-EGR): A dual-purpose solution that integrates wastewater treatment from the EGR system with bilge water separation. This can either be purchased as a combined unit or the standalone WTS can be upgraded to ensure compliance with necessary regulations for bilge water separation.

A Tailored Solution for Modern Vessels: Marinfloc’s WTS for MAN-ES EGR systems provides shipowners with the flexibility to select a solution that best fits their operational requirements, whether it’s standalone wastewater treatment or an integrated approach with the necessary upgrades for bilge water separation.
