Device for measuring solubility of solid components in supercritical fluids

摘要

System for measuring the solubility of solids in supercritical fluids, in particular carbon dioxide or methane, comprising a feed device (E1) delivering the fluid in a supercritical state under constant pressure, a saturation cell (10) in which the fluid is saturated with the component to be dissolved, and a receiver (E3) for the saturated fluid connected to the cell by a multi-way valve. The feed device contains a pump with a pressure regulator linked to complementary means of regulating pressure and temperature.
