Express leads the way in supercritical fluids
15 Jan 2000
Supercritical fluid (SCF) extraction is attracting increasing interest as an environmentally-friendly method for removing solvents and impurities from mixtures, but the high capital and operating costs of the equipment has kept it largely on the back burn
Express Separations, headed by Professors Tony Clifford and Keith Bartle of the university chemistry department's SCF research group, was originally launched in 1993. Now, however, the company claims to offer services ranging 'from initial laboratory scale trials to plant scale production.'
Services include techniques for removing metals from ores, tailings and contaminated soils by intermediary complex formation with supercritical carbon dioxide.
