SCALE-UP OF DISTILLATION-COLUMNS

Scale-up of Distillation Columns. In spite of remarkable advances in t he development of computer programs for calculations on distillation c olumns, it is frequently still impossible to design them without exper imental testing. Economic constraints demand use of miniaturised test plant, thus enhancing the importance of laboratory measurements. A sys tem is presented for scale-up of separation which required information from laboratory experiments, includes data from reference columns. an d takes account of models of fluid dynamics and mass transfer. The spe cial feature of this approach lies in the free choise of internals; bo th in the laboratory and in the designed column.
