Binary Distillation Trainer with DCS Control
Function: The separation of liquid mixtures and recovery of the components usually involves distillation. Distillation and fractionation operations are found throughout the petroleum, petrochemical and numerous other industries. This trainer separates a methanol/water mixture in a see-through, bubble cap tray column. The trainer is equipped with industry-typical process measurement and control devices. The entire trainer is controlled from an optional distributed control system or control panel.
