Efficient fully controlled up-to-date equipment for catalytic treatment of waste gases

This paper describes research and development of a new unit for catalytic destruction of waste gases polluted mainly by volatile organic compounds (VOC), halogenated organic compounds (HOC) or carbon monoxide. Novel equipment has considerable advantages compared with commonly used arrangement (combustion chamber (catalytic reactor)–pipeline–heat exchanger). It is very compact and light and has the combustion chamber, catalytic reactor and heat exchanger integrated into one unit. Maximum utilizing heat losses in the combustion chamber and catalytic reactor is achieved. During the development of this unit experience from tests of previously developed equipment used for thermal treatment of waste gases was used, as well as from experimental studies of catalytic disposal of various VOC carried out in the newly built experimental unit. During the development calculation methods were created allowing design modifications of this unit for real industrial applications. The newly developed unit can be used in various branches of industry such as paint shops, refining plants, sewage treatment plants, food processing industry, pharmaceutical industry, but also in companies processing and transporting crude-oil or natural gas, etc.
