Model hone flashbar 4400 analyser - cod. produto nv2544; ; ; the model 4400 flashar is completely automatic process steam analyser for the determination of flash point. the analysis can be performed to correlate with either astm d93 or d56 standard test.; ; ; ; ;;the monitoring of crude distillation side stream strippers;; ;;heating oil blending;; ; ; ; flash points are determined by particular vapour/ air concentration above the surface of the liquid hydrocarbons. when a critical concentration is reached, flashing occur on applying a test flame. the flash point of a liquid hydrocarbon is influenced largely by the lighter, more volatile components, since these are more easily vaporized. in the flashar continuous flash point analyser a test flame, as specified for the standard laboratory test is not used to detect the flash point. instead a platinum palladium catalyst is used to detect the critical hydrocarbon vapour concentration that corresponds with the flash point. this particular vapour/ air mixture reacts on the catalyst surface to produce a reproducible catalyst temperature. it is the different between this temperature and and the temperature caused by concentrations other than critical (flash point) concentration that is used to control the heat applied to the fresh sample feed before it is mixed with air. if the vapour/ air mixture flowing over the catalytic detector is below flash point concentration, then the detector temperature falls. ;
