Emission control
GEA provides cost-effective emissions reduction solutions for the existing fleet of both coal-fired power plants and waste-incineration plants.
Our know-how for new generating capacity projects continues to demonstrate the viability of our technology to meet even the most stringent air quality standards.
The Spray Drying Absorption (SDA) process is a versatile way of cleaning flue gases by the removal of acid gases and particulates generated by fossil-fuel burning, mainly coal. Because of the presence of large volumes of flue gasses, power plant installations frequently have more than one Spray Dryer Absorber module.
The end product from Spray Drying Absorption consists of the reaction products, excess absorbent and fly ash. SDA systems can be effectively retrofitted into sites with limited space and typically are brought on-line during a brief tie-in outage, thus minimizing disruption to the power generation.
Waste incinerator applications are generally characterized by relatively low gas. The smaller plant size and the composition of acid content typically favor single-pass designs. The drying properties of the absorber, high chloride content in the inlet gas, single pass mode, etc., call for a design with higher retention time in the absorber chamber, and therefore the plants are operated at high outlet temperatures.
A single, centrally located rotary atomizer minimizes the potential for wall wetting and deposition, which provides optimum reagent utilization. Its abrasion-resistant construction and flexible shaft design can tolerate imbalances and provides reliable, continuous operation between scheduled maintenance.
Our goal is to reduce the emissions of:
Worldwide, more than 200 Spray Drying Absorption plants are installed at power stations, steel plants, waste incinerator plants, and at plants burning hazardous waste. They all share one common trait: They are operated in accordance with or above required performance stipulations as laid down by local authorities.

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.
