Emission control
GEA´s economical solution for emission control in the chemical industry
GEA's technology has proven itself in numerous of applications for emission control:
Gas scrubbing plants for process and environmental technology
We specialize in jet and venturi scrubbers which are used with a high success rate for cleaning and de-dusting of discharge air, absorbing noxious gaseous substances, separating aerosols and cooling gases.
Our offering often includes combinations of emission control devices depending on the application.
Jet scrubbers are unique among gas scrubbers. They work on the injection principle and are the only scrubbers which produce an increase rather than a loss in pressure in the gas flow. Thus, when using a jet scrubber there is generally no requirement for a mechanical ventilator for extracting and conveying the gases.
Additional packing or trays are installed into the scrubber’s separator as counter-flow columns for fine cleaning. Depending on the particular application, jet scrubbers can also be designed with several effects or combined with Venturi scrubbers or aerosol separators.
Jet scrubbers are particularly suitable for use with explosive gas mixtures and heavily dust-laden and highly corrosive gases. They can also be conveniently installed into existing plants at a later date.
Compact scrubbing units and emergency scrubbers
We have developed gas scrubbers in compact design for gas quantities of up to 2,000 m³/h. They are often used in chemical laboratories during testing, in production, filling, draining, and cleaning of equipment whenever very small flows of discharge air have to be drawn off.
In the event of an accident caused by escapes of chlorine or other toxic substances from leaking storage containers or dosing plants, GEA has developed compact emergency units, which operate according to the principle of the jet scrubbers.
Jet scrubbing plants are perfectly suited to the cleaning of exhaust air from chemical reaction processes, production buildings, container de-aeration, and tank wagon emptying.
Titanium Dioxide Calcining
Titanium dioxide is produced through two processes: the chloride process and the sulfate process and both generate different but significant process-related emissions.
GEA offers the removal of dust and sulfuric acid mist using venturi scrubbers and wet electrostatic precipitators.
Sulfuric Acid Recovery Plants
GEA offers for the removal of sulfuric acid mist wet electrostatic precipitators and washing and cooling systems

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.
