A Case Study For Thermal Treatment Of Fluorinated Hydrocarbon With 15% Wt Hydrofluoric Acid Recovery
This paper is a joint presentation by 3M Specialty Materials and Selas-Linde to describe the thermal treatment technology used to safely destroy Fluorinated Hydrocarbon components generated as a result of fluorination of organic compounds. Thermal treatment of these components results in high concentration of Hydrogen fluoride in the combustion chamber requiring special attention to handling and selection of materials of construction. The plant is provided with a dedicated downstream Air Pollution Control system designed not only to scrub the flue gases to comply with European emission legislation, but also to recover Hydrofluoric acid at a concentration of 15% wt as by-product. The case study also covers topics such as measures for increased plant availability, problems associated with treating fluorinated wastes and the resulting solutions to overcome the encountered difficulties.
