146.Pour point and flash point

February 13, 2019 Posted by AK No comments
The pour point of a liquid is the temperature below which the liquid loses its flow characteristics. In crude oil a high pour point is generally associated with a high paraffin content, typically found in crude deriving from a larger proportion of plant material.

The flash point of a volatile material is the lowest temperature at which vapours of the material will ignite, when given an ignition source.
