As global emission regulations become increasingly stringent, ship operators are required to reduce nitrogen oxides (NOx), sulfur oxides (SOx), and particulate emissions. Exhaust Gas Recirculation (EGR) is an established technology for NOx reduction, enabling compliance with IMO Tier III requirements across a wide range of fuels, including heavy fuel oil, low-sulfur fuels, LNG, and methanol.

During the EGR process, a portion of the exhaust gas is washed and recirculated, generating wash water containing soot, acidic compounds, sulfur residues, and fine particulates. This water must be treated before discharge to prevent environmental impact and to meet regulatory requirements.

GEA Westfalia Separator: EGR wash water treatment for compliant discharge

GEA EGR wash water treatment systems are designed to purify bleed-off water from EGR circuits, ensuring compliance with IMO MEPC.307(73) and, where required, MEPC.259(68). High-efficiency centrifugal separation removes solids and contaminants, allowing the treated water to be safely discharged overboard in accordance with applicable regulations.

The compact, integrated design supports continuous operation with low energy consumption and minimal maintenance requirements. Automatic sludge handling and direct-drive technology ensure reliable performance and stable separation efficiency under varying operating conditions, supporting compliant and efficient EGR operation onboard marine vessels.

Fuel quality is critical to the safe, efficient, and reliable operation of gas turbines and engines. Even trace amounts of water, solids, salts, or catalytic fines can lead to corrosion, fouling, accelerated wear, and unplanned downtime. GEA fuel oil treatment systems ensure consistent compliance with OEM fuel cleanliness requirements for gas turbines and engines, regardless of whether diesel oil, marine diesel oil (MDO), crude oil, or heavy fuel oil (HFO) is used.

GEA Westfalia Separator: Protecting engines with advanced fuel oil treatment

During transport and storage, distillate fuels such as diesel oil are frequently contaminated by water, rust, sand, and scale, often exceeding allowable limits. Crude oil and HFO present additional challenges, including high viscosity, wax content, low flash points, and elevated concentrations of sodium, potassium, vanadium, and abrasive solids. Effective fuel oil treatment requires controlled heating (when needed), explosion protection (where applicable), and high-efficiency separation.

GEA fuel oil treatment solutions utilize centrifugal separation technology (centrifugal force), configured as single-stage or two-stage systems depending on fuel type and contamination level. By delivering clean, specification-compliant fuel, GEA fuel oil treatment systems protect critical components, including turbine blades, injectors, pistons, and cylinder liners. The result is reduced corrosion and fouling, longer maintenance intervals, improved operational reliability, and lower lifecycle costs across power generation, maritime, and industrial applications.

Lube oil needs to have water and other impurities removed continuously. Lube oil treatment is the only reliable way to prevent symptoms of premature wear and damage to critical components. Lube oil treatment extends the service life of the lube oil.

Lube Oil Treatment for Diesel Engines

During normal diesel engine operation, lubricating oil is continuously exposed to contamination. Wear from rotating and sliding components introduces fine metallic particles into the oil. In addition, combustion byproducts, condensed moisture, and decomposition residues accumulate in the lube oil sump over time.

GEA Westfalia Separator: Lube oil treatment for engines, engineered for reliability

The lubricant itself may also contain acidic compounds, which, when combined with catalytic contaminants, accelerate chemical degradation and lead to premature oil ageing. In diesel engines, combustion residues and non-combustible particles originating from the cylinder can migrate into the lubricating oil circuit. If left untreated, these contaminants directly contribute to increased engine wear on critical components, including bearings, pistons, and cylinder liners, ultimately reducing engine reliability and service life.

Lube Oil Treatment for Gas Turbines

In gas turbine power plants, lubricating oil is essential for protecting rotating components and maintaining stable, efficient operation. During service, the oil gradually becomes contaminated with fine metallic wear particles, airborne dust, moisture, and thermal decomposition byproducts. These contaminants accumulate in the lube oil sump and accelerate oil ageing, particularly when acidic compounds interact with catalytic impurities.

Water ingress represents a significant operational risk. When not effectively removed, moisture promotes oxidation and microbial activity, resulting in premature oil degradation and increased maintenance requirements. If left unaddressed, these conditions can adversely affect turbine reliability, shorten component life, and lead to unplanned downtime.

Cost savings have become a very attractive proposition on board ships as operating costs have risen sharply. The overall economy and reduced fuel consumption are essential to becoming more competitive and operating a green, environmentally friendly vessel.

In traditional lube oil treatment systems, the energy required to heat the lube oil upstream of the centrifugal separator is lost because, after separation, the hot oil is returned to the engine sump tank for cooling by the engine cooling system. As an integral part of the lube oil treatment system in compact unit design, the GEA Westfalia Separator EnergyMaster recovers part of this energy. The recovery heat exchanger is the heart of this system and is designed as a brazed plate heat exchanger.

GEA Westfalia Separator: Heat recovery engineered for sustainability and efficiency

The GEA Westfalia Separator EnergyMaster is available as
– An integrated part of the heater unit, HRU
– A retrofit package for existing heater units

The GEA Westfalia Separator EnergyMaster saves energy on the separator preheater system, and the same engine is saved on the engine lube oil cooling system.

Continuous hydraulic oil treatment is recommended to remove contaminants, such as water, dirt, and metal particles, which can cause corrosion, blockages, and system malfunctions. Using centrifugal force, GEA Westfalia Separators are perfect for this continuous treatment process, and can remove metal particles down to 1 μm, organic particles down to 5 μm, and can achieve a purity of up to 99.99% by volume.

GEA Westfalia Separator: Hydraulic oil treatment for reliable system performance

With cleaner hydraulic oils and longer oil-change intervals, industry and agriculture benefit from longer component service life, reduced machine downtime, and lower oil purchasing and disposal costs.

Storing large volumes of fresh water onboard is costly and consumes valuable space. GEA seawater desalination systems provide a shore-independent freshwater supply by converting seawater into potable water, with capacities of 5–30 tons per day, meeting the daily needs of container ships, LNG carriers, bulk carriers, and general cargo vessels.

GEA Westfalia Separator: Desalination systems engineered for marine and offshore operations

GEA Sea Water Distillers (SWD) use vacuum distillation to separate water from salt and impurities. Seawater is heated under vacuum, typically using waste heat from the main engine jacket water, causing partial evaporation. A combined air-and-brine ejector removes brine and non-condensable gases while maintaining the required vacuum level. The generated vapor is cleaned through a demister and then condensed in a titanium plate condenser cooled by incoming seawater.

The distillate quality is continuously monitored by a salinity measuring unit. If the salt content exceeds the set threshold (commonly 2–10 ppm), the water is automatically returned to the evaporator. Treated water can then be stored and, if desired, re-hardened to restore its mineral content for domestic use.

All seawater-contacting components are manufactured from corrosion-resistant materials, including titanium, stainless steel, and high-performance polymers, ensuring long-term durability and reliable operation. This efficient desalination process reduces reliance on stored freshwater, supports continuous onboard water production, and improves operational autonomy for marine vessels.
