摘要

The mass transfer of the system CO{sub}2-water was measured up to a pressure of 360 bar at a temperature of 25℃ and the results were compared to empirical predictions. The influence of a surfactant on the mass transfer was investigated. A Schlieren method and a three-mode magnetic suspension balance connected to an optical cell were used to analyse the mass transfer. A good simulation of the experimental values was achieved by linear superposition of free convection and Marangoni convection. The surfactant enforces the Marangoni convection while the solubility of CO{sub}2 stayed unaffected.
