On the Determination of the Diffusivity of CO 2 in Aqueous and NonAqueous Solvents: Investigations with Laminar Jets and Wetted Wall Columns

Autor: Geert Versteeg, RD Vas Bhat, J.A. Hogendoorn

Publikováno v: Chemical Engineering Communications, 189(8), 1009-1037. Taylor & Francis Group

The diffusivity of CO2 in ethanol, n-heptane and methyl tertiary butyl ether (MTBE) has been determined using a laminar jet reactor and a wetted wall column at two temperatures (293 K and 298 K). The reactors have been operated in the laminar and tra
