GEA crude oil Dehydrator
GEA crude oil DehydratorGEA crude oil Dehydrators are nozzle-type disk stack centrifuges. They are the right choice, if the main task is to reduce the water content of the crude oil and if the solids content varies.
These centrifuges are built for high performance by incorporating the know-how of more than 50 years of successful operation in the Canadian oil sands industry into their design. Robustness, high efficiency, ease of use and predictable maintenance costs are some of the main advantages.
Operating principles and constructional features
In a nozzle centrifuge, the solids and water are continuously removed through open nozzles placed on the outer diameter of the bowl. At the same time, oil and water are continuously separated by the high g-forces and removed from the top of the bowl under pressure. By using a large number of densely packed disks, the clarification space is significantly increased compared to static separators, thus further improving the oil-water separation.
Depending on the required capacity, GEA supplies the following machine types:
- GEA crude oil Dehydrator 130
- GEA crude oil Dehydrator 260
GEA crude oil Dehydrators are available with a direct driven or with a belt driven bowl.
Features
- Single unit capacity up to 37,500 BPD (250 m3/h); can easily be extended by combining several units
- Oil gravity > 12° API
- Flexible adjustment of the separating zone for maximum separation efficiency of the liquid phases
- Special wear protection including replaceable wear liners
- All product containing parts are made from high-grade stainless steel material
- Space-saving design
- ATEX compliant for the operation in ATEX Zone 1 and Zone 2 environments

GEA crude oil Desalter
GEA crude oil DesalterGEA crude oil Desalters have a self-ejecting disk-stack bowl for the separation of oil, water and solids. They are the right choice, if the solids content is limited and if the main purpose is to reduce the salt content of the crude oil.
These centrifuges have been designed specifically for crude oil applications and cover the entire range of possible capacities. They are characterized by high motor performance and optimum dynamics with low energy consumption. Other advantages include high reliability, ease of use and low maintenance costs.
Operating principles and constructional features
In the rotating bowl, the salt-charged water and fine particles are separated from the crude oil. The desalting efficiency can be improved by adding fresh water upstream of the centrifuge to extract water-soluble salts from the crude oil. Water and crude oil are discharged continuously under pressure, with the solids collected in the holding space and being automatically ejected at regular intervals.
Depending on the required capacity, GEA supplies three options for this application:
• GEA crude oil Desalter 80
• GEA crude oil Desalter 120
• GEA crude oil Desalter 200
The GEA crude oil Desalter 200 is available with direct drive, both the versions 80 and 120 are available as belt-driven machines.
Features
- Single unit capacity up to 12,500 BPD (85 m3/h); can easily be extended by combining several units
- Oil gravity > 12° API
- Closed feed and discharge for the product phases
- Flexible adjustment of the separating zone for maximum separation efficiency of the liquid phases
- Special wear protection including replaceable wear liners
- All product containing parts are made from high-grade stainless steel material
- Space-saving design
- ATEX compliant for the operation in ATEX Zone 1 and Zone 2 environments
- BS&W and water-soluble salt are brought to pipeline / refinery quality

How does centrifugal dehydration and desalting work?
Centrifugal dehydration and desalting work by exploiting density differences: high g-forces inside a rotating bowl separate crude oil (lighter) from water and solids (heavier). In dehydration, water and solids are continuously ejected through nozzles; in desalting, fresh wash water is mixed with the crude upstream, dissolving salts, which are then removed along with the water phase in the centrifuge.

When should I choose a Dehydrator vs a Desalter?
Choose a Dehydrator when your primary goal is water removal and solids content is high or variable. Choose a Desalter when solids content is limited and your main objective is salt reduction to meet pipeline or refinery specifications.
Practical guidance:
- Upstream (oil field): Dehydrator is typically preferred due to high water cuts (often 30–70%) and variable solids from production.
- Midstream (tank-to-tank, pipeline prep): Dehydrator for bulk water removal, Desalter if salt specs are critical.
- Downstream (refinery): Desalter is standard for final salt removal before atmospheric distillation (target: <10 PTB salt).
- Combination approach: For very challenging crudes (high water + high salt), a two-stage system (Dehydrator followed by Desalter) may be optimal.
- Modular flexibility: Both units can be combined in parallel or series configurations to match your specific process requirements and flow rates.

FAQ
What is the difference between an industrial crude oil centrifuge and a laboratory centrifuge?
Industrial crude oil centrifuges are large-scale continuous process units (up to 250 m³/h) for meeting pipeline specs, while laboratory centrifuges are small benchtop devices for analyzing oil samples.
How does a centrifuge compare to static separators or electrostatic desalters?
Centrifuges use high g-forces for faster, more thorough separation—especially in heavy or emulsified oils—resulting in a smaller footprint, lower temperatures, and reduced chemical use compared to conventional systems.
Can GEA centrifuges handle heavy crude oil with low API gravity?
Yes, GEA systems process heavy and opportunity crudes with oil gravity > 12° API by using high centrifugal force to break stable emulsions effectively.
What are the typical maintenance requirements for a crude oil centrifuge?
Maintenance focuses on wear-protected rotating parts with replaceable liners, ensuring > 98.5% uptime and predictable service intervals supported by global 24/7 service agreements.
Is the system suitable for offshore or remote locations?
Yes, the compact modular design fits space-constrained environments like offshore platforms, with container or enclosure options available for rapid deployment in remote locations.
Does the system comply with international safety and environmental standards?
All units are ATEX-compliant for Zone 1 and Zone 2 hazardous areas and help meet environmental regulations by maximizing water removal and minimizing chemical use.

The breakthrough that changed spray drying
In 1976, NIRO engineers responded to a competitive challenge by rethinking what spray drying could do. Their idea became the multi-stage dryer MSD. Fifty years later, the same fundamental principle helps turn liquids into the powders used in essential nutrition products and important medicines around the world. Refined through decades of engineering expertise, customer insight and continuous development, MSD is a story of innovation with lasting impact.
Oltre le macchine: come migliorare le prestazioni dell’impianto
Una macchina efficiente non garantisce automaticamente l'efficienza di uno stabilimento. Il vero miglioramento spesso inizia guardando oltre le singole attrezzature e comprendendo come i processi, i sistemi energetici e le decisioni operative si influenzino a vicenda. Si tratta di un approccio olistico pensato per individuare opportunità che altrimenti potrebbero sfuggire.
Come una valvola rivoluziona la produzione di alimenti e bevande
Negli impianti di produzione di alimenti e bevande, le valvole vengono solitamente azionate tramite aria compressa. GEA Hydract® Actuation Technology utilizza l'acqua all'interno di un circuito chiuso e controllato digitalmente. Il risultato è una valvola che può essere mantenuta esattamente in posizione e regolata con per piccoli incrementi con grande precisione. Ciò si traduce in un minor consumo energetico e in un maggiore controllo.
