Scrubber Test Facilities at Karlsruhe R&D Center

Availability of mobile pilot plants for different kind of scrubber systems.

gea-logo

With state-of-the-art pilot plants and test benches our R & D Center is optimally equipped for testing in the fields of gas scrubbing technology.

Most pilot plants are mobile so that it is also possible to perform tests on our customers' premises. 

Our physico-chemical laboratory is designed to determine and analyze important physical characteristics such as viscosity, boiling point elevation, thermal conductivity and maximum final concentration.

Moreover, complex quality parameters can be determined in our analyzing laboratory with GC and HPLC.

We use the latest software and hardware to simulate the operating behaviour of the plants and adapt them to individual customer specifications. The determined process parameters and substance properties are directly used for the design of our plants.

The following pilot plants are available for testing:

  • Mobile laboratory scrubber system DN80 consisting of liquid jet scrubber unit with packed column on wheels . Material of construction  PP
  • Mobile laboratory scrubber system DN80 consisting of liquid jet scrubber unit with packed column on frame. Material of construction  PP
  • Mobile liquid jet scrubber DN600. Material of construction glass fiber reinforced
  • Mobile venturi scrubber DN 250. Material of construction titanium
  • Stationary hot gas quench DN 350 for spray nozzle tests

Combination of above stated systems and arrangements of process lines consisting of different technologies (e.g. membrane filtration, distillation, evaporation, centrifuge, decanter, dryer, etc.)
