Integrated Pilot Plant
The IPP demonstrates the operation of a process plant using a water/ethyleneglycol mixture as the main medium.
The IPP consists of three units:
Field Process (FP)
Distillation Process (DP)
Utility Unit (UU)
Common process control loops with control variables like temperature, pressure, level and flow rate are part of the field process.
Field process and distillation process can be operated separately as well as together.
The distillation process separates the water/ethylene glycol mixture into its components. The distillation takes place in a rectification column with several bubble cap trays. The bottom product and the top product are remixed and led back to the field and distillation process. Both require the utility unit to receive their auxiliary media. Important components of the plant are redundant to allow switchover for repair or maintenance work without shutting down the plant.
