<p>#CMT# #/CMT# The method involves carrying three measurements of content of pollutant or group of pollutants in fume in a time period of eighteen months, and carrying three tests of activity of a catalyst with regard to another pollutant or another group of pollutants in a time period of eighteen months. A correction function is determined by combining a composite score and the results of the three measurements. Threshold time (t-s) for which content of the pollutant or the groups of target pollutants attains a predetermined threshold value (S) is determined by utilizing the correction function. #CMT# : #/CMT# An independent claim is also included for a method for purifying fume. #CMT#USE : #/CMT# Method for predicting activity of catalyst with respect to pollutant or groups of pollutants e.g. dioxin, furan, nitrogen oxides and/or phenols (all claimed), in fume from a chimney of an industrial installation. #CMT#ADVANTAGE : #/CMT# The method enables predicting the moment at which the total or partial replacement of catalyst is necessary, in a convenient manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a graphical view illustrating variation of dioxin and furan according to time. C : Curve S : Predetermined threshold value t-s : Threshold time.</p> |
