Marangoni-convection and mass transfer from the liquid to the gas phase
Abstract
In chemical engineering practice, packed columns are widely used for separation processes, such as distillation, absorption, and desorption. Although such columns have been in use for more than fifty years, there remain problems regarding a satisfactory design procedure for such equipment. These problems are related to the complex relations between the various factors which affect the operational processes involved. In particular, effects related to surface tension are important. Investigations of the effects of surface tension (Marangoni effects) are difficult because of the disturbing influence of the density parameter. It is planned to overcome these difficulties by conducting an experiment in Spacelab under microgravity conditions. The results of the experiment are to make it possible to distinguish between effects due to surface tension gradients and density gradients. Details regarding this experiment are discussed.
