Low-pressure catalytic system for Voc removal

Purifies Exhaust Air Through Catalytic Oxidation

The Low-Pressure Catalytic Oxidation System from Dürr is engineered to support VOC removal across varied industrial applications, including chemical and pharmaceutical production, as well as in coating and surface treatment. At its core, this system employs a catalytic process where exhaust air, preheated through an air-to-air heat exchanger and further heated via a burner, is converted into carbon dioxide and water vapor at a catalyst temperature of 300 to 350°C. It efficiently purifies exhaust gases with diverse hydrocarbon compositions and concentrations, supporting continuous, automated operations. The system’s design includes key components such as a heat exchanger, support burner, and reactor with a catalyst in a honeycomb structure, promoting both energy efficiency and effective VOC breakdown. Its autothermal capability minimizes energy consumption by maintaining necessary temperatures via heat recovery, eliminating the need for additional heat sources. The system fits seamlessly into existing production lines and is adaptable to specific operational needs with customization options, ensuring reliable and safe air purification.
