From Adsorption Plants
The VOC-concentrator eliminates volatile organic compounds (VOC) from a low-concentrated exhaust air volume and sets the adsorbed solvents free in a high-concentrated small exhaust air volume for further treatment. The VOC-containing process exhaust air is guided via a pre-filter and flows through the absorption zone. There the VOC are removed and the cleaned air leaves the rotor.
The adsorbed VOC are removed from the rotor in the desorption zone and thereby concentrated. At this the small desorption air stream is heated-up in the cooling zone and then with approx. 200 °C in counter-current guided through the desorption zone. The high-concentrated small exhaust air volume leaves with 50 °C the rotor and is supplied to a thermal oxidation plant (RTO) for further treatment.
