About CTP Air Pollution Control
CTP Chemisch Thermische Prozesstechnik GmbH, headquartered in Graz, specializes in industrial air pollution control and has been active since 1985. The company develops and manufactures turnkey systems for the removal of VOCs, odor substances, carbon monoxide, NOx, ammonia, hydrogen sulfide and nitrous oxide, including thermal and catalytic oxidation systems (RTO, VOXcube, AutoTherm, MultiTherm, RecuKAT, AutoKAT), hybrid systems (RTO-i-SCR, VOCNOxTherm) and sorptive systems (RotorSorbTherm, WetSorbTherm, VOXsorbTherm). The value chain ranges from process consulting, feasibility studies and HAZOP studies through pilot tests and in-house steel and plant manufacturing to installation, commissioning, maintenance, retrofitting and spare parts management. Waste gas flows treated reach up to more than 420,000 Nm³/h, as with the RTO system for a cement plant in Texas. Customer industries include, among others, cement and lime, wood products, chemicals and petrochemicals, oil and gas, automotive and pharmaceuticals. In addition to its headquarters in Graz, CTP maintains locations in France, China, Korea and St. Paul (NCA container and plant construction, production); systems are in operation in over 40 countries on all continents.
