Emission control
Cement
Our modern world is inconceivable without cement. It is the basic building material for the most varied construction tasks. Cement is the most important component for manufacturing concrete. The production is a demanding process involving a number of processes and technologies.
GEA´s solution for clean air in a sustainable cement production
Cement is made today in modern cement plants in a continuous dry process from natural raw materials with clinker burning process. This high energy-consuming and greenhouse-gas–emitting production reach an output of 3,000 to 10,000 tonnes of clinker per day.
GEA technologies stand for dust emissions below traceability with lowest energy costs. Even reliable desulphurization with scrubbers is not an issue at all.
Our innovative clean gas SCR technology guarantees a reliable low NOx content in the kiln off gas with even no ammonia slip, far below existing environmental regulations. Waste heat recovery counts to one of our innovative technologies, where we harvest the thermal energy of the pre-heater tower and/or the clinker cooler to produce electric energy with an ORC plant. GEA technologies do not only support you to lower your environmental footprint, they will lower your operating costs significantly as well.
In the cement production sector, we provide technologies for the following fields of application:
Dust control
Our ECOpuls bag filter stands for dust emissions below traceability, smooth bag cleaning (expanded lifespan) as well as significant low energy consumption.
NOx Control (DeNOx)
Our clean gas selective catalytic reactor (SCR) allows highest conversion rates at lowest ammonia slip combined with a high availability.
Desulphurization (DeSOx)
Our wet scrubber design is operated with raw-meal as reagent and formats excellent gypsum for the use in the finish mill.
Waste heat recovery
Our waste heat recovery system combines proven ORC technology with innovative heat exchanger design to harvest most of the waste thermal energy out of the cement process. Our recent plant produces more than 4 MW electric energy.

Catalytic gas cleaning
Selective Catalytic Reduction (SCR) diminishes post-combustion NOx by reacting with urea or ammonia to produce nitrogen and water.
CO2 saving processes
CO2 savings come from reducing fossil fuel demand either by increasing energy efficiency or by separating CO2 from flue gas streams along with long-term fixation in valuable products or storage. GEA offers products and processes for all relevant stages.
Cooling, quenching & conditioning
The Rapid Cooling or Quenching of gas streams is used in several essential applications in the process industries.
Filtration and Separation

The next era of food production with GEA NEXUS
Climate change and a growing world population put increased pressure on the energy-intensive food industry to feed more people without further impacting the planet. George Shepherd, GEA’s Global Technical Sustainability Manager, explains how GEA uses its engineering know-how to help processors produce more sustainably yet increase productivity.
Making milk production more sustainable for a growing world
The world's population is growing and with it demand for milk. Dairy is an essential component of many global diets. However, its production can be resource-intensive and impact the environment. GEA’s Christian Müller, Senior Director Sustainability Farm Technologies, sheds light on how technological innovations powered by GEA make milk production more efficient and profitable.
