Abstract

This paper describes the use of the pressure drop across a packed column to locate phase transitions in high-pressure fluids in continuous flow. The pressure drop method yields data that can be used to locate phase transitions objectively, and an example of an automated searching algorithm is demonstrated as a proof of concept. Finally, we demonstrate the ability of the pressure drop method to be applied in operand to a hydrogenation reaction.
