Rectification is an extension of the distillation or a series of many distillation steps. The main advantages of rectification are a continuous operation of the unit and the separation effect is much higher in comparison to distillation. The contact areas between the steam and liquid phase are enhanced through a bubble tray. The boiling temperature differences between top and bottom and the thermodynamic performance of the top product decide, whether the MVR, TVR or multi-effect distillation will be applicable. GIG Karasek offers a package, comprising engineering and supply of the plant including control system, erection and start-up assistance.
