Groundwater treatment plant for the removal of benzene

The crude gas loaded with organic impurities (benzene) is supplied to the plant by means of the exhaust fan. First, the raw gas enters the air/air heat exchanger with a downstream electric heater, where it is preheated to 320 °C. After the heater, it enters the reactor, where it is heated to 400 °C by oxidation. During the flow through the catalyst bed, the pollutants are oxidized. After the catalyst, the purified exhaust gas flows through the heat exchanger, where it is cooled to about 180 °C. After the heat exchanger, the cleaned exhaust gas leaves the plant.
