英文摘要: Abstract(#br)Sizing of large scale pervaporation units from experimental data requires mathematical models which can predict the pervaporation process performance adequately. In this work, a modeling approach is reported with a semi-empirical flux model regressed over experimental flux data measured at lab scale. The regression approach generates a temperature and concentration dependent flux function that can be solved simultaneously with material and energy balance over the length of a pervaporation module. For a binary mixture only four parameters are required for model fitting which can be obtained using lab-scale data: temperature and concentration of one component on feed side, permeate side pressure, and component flux. The semi-empirical flux model was verified using two separate...
