| 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. |

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.

| This is sensed,
compared with the " set point" temperature for the flash point concentratin,and
the difference used to increase the that to the liquid feed. As the sample
temperature increase more vaporization occurs, until the flash point
concentration is reached and the detector is again at the set point
temperature. The reverse occurs when vapour / air mixture is above flash point
concentration, and the heating of the liquid is reduced. |
