Möglichkeiten zur Prozeßintegration bei destillativen Trennverfahren

Possibilities of process integration in distillative separation processes. Distillation is the most important method of separation in the petroleum and chemical industries. About one quarter of the energy consumed in these sectors of industry is for distillation. This underscores the importance of improving distillation processes. Optimisation work on distillation processes has been in progress for a long time. Attention has recently been turned to the treatment of overall separation tasks which can be integrated into chemical engineering processes. To this end, the heuristic rules usually employed in the design of distillative separations have been further developed. Use of expert systems which transform these heuristic rules into separation proposals already appears feasible.
