NOx emission reduction
GEA NOx Separator with integrated direct drive is specially configured for the water treatment in Exhaust Gas Recirculation (EGR) on board marine vessels. After treatment, the purified water can be discharged into the sea.
As environmental regulations on exhaust gases become more stringent, the shipping industry is under pressure to reduce emissions of nitrogen oxides (NOx), sulfur oxides (SOx), and fine particulates.
Exhaust Gas Recirculation (EGR) is a NOx emission reduction technology that ensures IMO Tier III compliance in both diesel and gas operations. Engine manufacturers offer their customers engines with EGR systems for heavy fuel oil (HFO), low-sulfur fuels, liquefied natural gas (LNG), and IMO Tier II and Tier III methanol.
When incorporating EGR technology into marine engines, it is important to consider the treatment of EGR wash water prior to its discharge into the ocean. The recirculated exhaust gas in the EGR process can potentially interact with contaminants such as soot, sulfur compounds and acidic substances.
The GEA NOx Separator is designed for a single task. The system purifies the bleed-off water before discharge according to MEPC.307(73) and optionally to MEPC.259(68).
The GEA marine Separator
Marine separators specialize in the purification of fuel and lube oil as well as bilge and EGR water treatment on board ships.
Designed to automate various separator processes, the GEA marine Upgrade Kit features advanced software and easy-to-use hardware components for seamless integration. By extending the capabilities of our marine separators, this solution improves efficiency and promotes environmental sustainability.
GEA bilge Separator with integrated direct drive is designed for cleaning oily water and producing minimum residual oil contents in all performance classes.
GEA bilgEGR Solution is a combined Exhaust Gas Recirculation (EGR) and oily bilge water system designed to treat water on board ships. After treatment, the purified water can be discharged into the sea.

What if your favorite chocolate didn’t require cocoa beans and your coffee was locally produced? As climate disruption, price hikes and ethical concerns hit two of our most beloved indulgences, scientists are reimagining how we produce them – using microbes, not monocultures. The goal: preserve the flavor and properties of coffee and chocolate while minimizing carbon emissions and improving food resilience.
Ports now compete not just on logistics, but on sustainability. At Greece’s Piraeus port, an advanced processing and recovery facility recycles ship waste oil into fuel. Equipped with GEA’s high-performance centrifuges, it sets a new benchmark for state-of-the-art, environmentally responsible port operations.
The 2022 CO2 shortage forced breweries to review their dependency on global supply chains. Many were forced to close, unable to carbonate their products. At its breweries in Germany, OeTTINGER GETRÄNKE is turning its own CO2 into a powerful lever for independence and sustainability – with the help of CO2 recovery technology from GEA.
