Disposal of waste gases alongside with disposal of solid and liquid wastes belongs to the most important activities that contribute to environmental protection. Gaseous wastes are produced mainly by industrial activities. If their production cannot be reduced, series of measures that ensure fulfillment of national and international limits must be taken. Currently, the tightening of emission limits increases pressure to reduce emissions of primarily volatile organic compounds (VOCs).The consequence of these emissions is a share to the "greenhouse effect," which causes warming of our planet and formation of the "ozone hole". It has a direct negative impact on humans and other living organisms, because it allows the penetration of dangerous radiation to the surface of the planet. VOC emissions occur mainly in industry processing the organic material, e.g. various chemical solvents, fuels, cleaning agents, paints and others. Such case is a chemical manufacturing company Momentive Specialty Chemicals, which products are from field of acrylic acid, its esters and acrylic polymers. In the premises of the company there are two thermal incineration plants of liquid and gaseous wastes. At incineration plants, there are processed waste waters, distillation residues and several types of waste gases. The operation of these units is energetically costly, because its operation consumes large amount of natural gas. Therefore, a search for technologies that would reduce natural gas consumption, while complying with current national emission limits was made by company operator. A Study that summarizes the current status, and explores the possibilities to replace the existing combustion chamber (furnace) 2F-630 and 2U-600 unit with a catalytic reactor technology was carried out. The current operator will get an overview of the technical feasibility and the potential financial costs of the project of the replacement of the existing combustion chamber. On the results of this study was followed up by pilot trial. Pilot unit was designed for exhaust gas flow rate 100 Nm3/h. On this unit has been in the long term (about 3 months) monitored fouling of the catalytic bed (pressure loss), removal efficiency of monitored pollutants and other technological parameters. The results of this study will be presented in this contribution.
