The rotor concentrator is a system at the service of other emission treatment technologies and is used when the waste gas flow rate is high but the VOC concentration is low to reduce the energy consumption of the pollution control solutions.
The pollution adsorption process is implemented by a concentration rotor containing zeolites which continuously guarantees the adsorption and simultaneous regeneration of part of the rotor. The waste air is conveyed by specific fans to the adsorption section of the concentration rotor where the pollutant is captured. The impurity-free air is discharged to the stack. Through the heating of a particular section of the rotor, the pollutant adsorbed is desorbed in a second stream with a much lower flow rate. This concentrated stream is sent to a thermal oxidation process for further treatment. Through such process, the low concentration, high flow rate waste gas can be transformed into high concentration and low flow rate one.
