We have carried out process design of continuos and batch distillation columns, strippers, scrubbers, absorbers and extraction columns. Besides using internationally proven Detherm software for experimental vapour -Liquid equilibrium data, we also assist client in generating experimental vapour -Liquid equilibrium data using their laboratory when such need arise. We have designed more than 120 columns and most of these columns are in operation. A list of columns designed by Alpha is attached
