Scrubbers
High performance separators for fine dusts and aerosols, available in different scales.
With GEA’s Venturi Scrubbers you benefit from a high separation efficiency that relies on the high relative velocity between the gas and the scrubbing liquid in the Venturi throat. Their main field of application is the treatment of gas containing very fine particulate matter or droplets, like aerosols, to meet the ever more demanding emission limit regulations.
The Venturi Scrubber is particularly apt for use with fluctuating gas streams: The free cross-sectional area for the gas flow is continuously adjusted during operation to allow for a steady and reliable performance.
In addition to standard design, GEA provides you with customized solutions that cope with gas quenching and treatment of gaseous pollutants in the gas. This is done by an adaptable nozzle arrangement and the appropriate choice of scrubbing liquid, respectively. Moreover, there are various arrangements available to fit with your individual spatial and process requirements.
Depending on the application, GEA delivers two types of Venturi scrubbers: The small to mid-scale scrubber is mainly used in the chemical industry whereas the large-scale Venturi scrubber is predominantly in use in the iron & steel and non-ferrous industry. Typical gas volume flow rates range from 1 to 300 000 m³/h.

Seeking to provide a flexible unit, capable of mastering manifold industrial off-gas problems, resulted, in 1950, in the development of an adjustable annular gap scrubber which today ranks among the outstanding high-efficiency scrubbers. As far as grain size of solid and liquid dust particles and concentration of gaseous components in a gas mixtu...
Next generation scrubber for more than the non-ferrous metallurgical industry. Used for dust and particulate removal in saturated waste gases, Linear Flow Scrubbers offer increased energy savings and efficiency thanks to their high adaptability, adjustability capacity to steadily scrub at fluctuating gas flow rates.
Versatile as fast absorber, de-duster or gas cooler. Operate according to injection principle: no pressure loss, but a pressure increase in the gas flow.
Adjustable flow scrubbers with high collecting efficiencies achievement even when working with critical substances. Mainly used for either gas cooling (to reduce the temperature by water evaporation) or gas cleaning (to condense aerosols and remove solid impurities).
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.
