NOx reduction by Exhaust Gas Recirculation
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.
EGR water treatment
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).

L'equazione dell'acqua
In tutta Europa, la siccità è una realtà ricorrente – e non è più limitata al sud. Sebbene la disponibilità idrica influenzi sempre più la scelta della sede delle industrie, il suo valore è determinato dal contesto locale. Esistono molte soluzioni tecnologiche per garantire l'efficienza idrica nei processi industriali, ma anche l'ubicazione, il fabbisogno energetico e altri fattori rivestono un ruolo fondamentale.
