GEA Showcases NOx Separator Advancements for Cleaner Dual-Fuel Ship Designs at Marintec 2025

GEA presents NOx separator at Marintec 2025
At Marintec China 2025 in Shanghai, held from 2–5 December, GEA highlighted new technologies for low-emission ship design, presenting the GEA NOx Separator as a key component for modern dual-fuel engines. As IMO Tier III regulations become more stringent, wash-water treatment in EGR and iCER systems has become essential for maintaining compliance and ensuring long-term engine performance.

Wash-water treatment for EGR and iCER systems
The GEA NOx Separator is engineered to remove contaminants generated in exhaust-gas recirculation, helping shipowners reduce nitrogen oxide emissions and maintain stable separation performance even in fluctuating engine loads. Its design supports both newbuild installations and dual-fuel configurations where methanol is increasingly used as an alternative fuel.

According to Li Bin, Senior Director Sales Separator at GEA China, the NOx Separator plays an important role in modern emission-reduction strategies: “By combining our separation expertise with next-generation wash-water treatment technology, we help customers meet demanding environmental requirements while ensuring the reliability they expect.”

Methanol as a next-generation fuel
Methanol dual-fuel propulsion is becoming more widely adopted, offering up to 65% lower greenhouse-gas emissions compared to conventional marine fuels. Although the maritime sector accounts for less than 3% of global GHG emissions, its relative share is expected to grow unless new fuels and technologies are adopted. Equipment that supports clean-fuel operation—such as EGR-based NOx reduction and wash-water treatment—therefore becomes critical for future vessel designs.




Deployment in Everllence and X-Press Feeders vessels
GEA’s NOx Separator has been selected for several methanol dual-fuel projects, including the Everllence 5S50ME-C9.6-LGIM+EcoEGR Tier III engines. These engines will power a series of 1,250-TEU container vessels under construction at Huangpu Wenchong Shipbuilding for Singapore-based X-Press Feeders. The first separators have already entered the commissioning phase.

Li Bin described the project as a milestone, noting that it demonstrates how wash-water treatment systems contribute to meeting advanced emission standards in next-generation propulsion.

Supporting green-ship design
GEA positions its Marine System Solutions portfolio as a comprehensive toolkit for shipowners preparing for lower-carbon operations. The product line supports regulatory compliance, operational efficiency, and the integration of alternative fuels, reflecting broader industry initiatives targeting low-emission shipping.

Through its collaboration with shipyards, owners, and engine manufacturers, GEA aims to further reduce the CO₂ footprint of maritime transport while improving the lifecycle efficiency of onboard machinery.
