Abstract
An effect of supercritical carbon dioxide compressive self-heating was observed both in stationary and flow regimes. The effect is probably caused by fluid compression in near-adiabatic conditions during system filling and pumping. This phenomenon should be taken into account in process design and optimization for systems employing sub- and supercritical fluids, such as supercritical fluid extraction, chromatography, aerogel drying etc.
