GEA is, among others, a single-source supplier of cost effective, energy efficient and reliable wastewater evaporator systems, based on using spray drying evaporation.
Drying of salt and solid-containing effluents from various industrial processes, including wastewater streams from wet type FGD (flue-gas desulfurization), is efficiently enabled using the well-proven GEA spray drying technology and proprietary equipment. The heat of the hot flue gas from the industrial process is used to evaporate the water in the effluent, leaving a dry powder to be collected in a downstream filter with no liquid effluent discharge at all.
Spray drying is a mature technology that was developed over a century ago. GEA has successfully delivered installations worldwide across many different spray drying applications in the power, waste to energy, sinter & metallurgical and glass industries — to name some.
The GEA spray drying evaporation process is highly efficient yet very simple, as it basically consists of the spray dryer evaporator module and a down-stream filter.
A slipstream of hot flue gas is fed into a spray-drying chamber where it immediately comes in contact with a fine spray from atomization of the discharged scrubber liquid of a wet FGD (WFGD) system.
There is a precise control of the gas distribution, the WFGD scrubber liquid flow rate and droplet size to ensure that all droplets are converted into a fine dry powder.
The flue gas further flows into an optional dust collector or the main filter where any remaining suspended solids are removed. The filtered flue gases are then fed to the wet FGD for acid gases removal.
Environmental pollution of heavy metals is increasingly becoming a problem and global concern. In addition to the calomel process, often used in the field of non-ferrous metal production, GEA uses wet Electrostatic Precipitators (ESP), Spray Drying Absorption (SDA) and Ceramic Catalyst Candles (BisCat) to reduce heavy metals from flue gas.
Bubble Columns feature a high liquid to gas volume ratio, beneficial when conducting rather slow reactions in the liquid phase as large reaction volumes can be realized. Ideal when dry spots must be avoided in the contactor.
The conversion of hot metal into steel produces CO-laden gases of high caloric value. The recovery of these gases means to save a considerable amount of energy. The LT-Steel Gas Process has established worldwide.
