Boiling under Reflux & Distillation with Coil Heat Exchanger

DDPS-Diagram-reflux-he-Rev1

The vessel attachment can be equipped with measuring and control devices according to the process requirements.

The following measuring instruments are generally sufficient:

  • Thermometer (Pt100) - vapor line
  • Recovery of hydrochloric acid
  • Flow meter with local display - distillate flow
  • Pressure gauge with local display – vapor line

Boiling under Reflux & Distillation with Shell & Tube Heat Exchanger

DDPS-Diagram-reflux-he-Rev1

The vessel attachment can be equipped with measuring and control devices according to the process requirements.

The following measuring instrumentation is generally sufficient:

  • Thermometer (Pt100) - vapor line
  • Flow meter with local display - distillate flow
  • Pressure gauge with local display - vapor line

Distillation with Phase Separation

DDPS-Diagram-distillation-HE-Rev1

In addition to the apparatus described above, this setup includes a phase separation vessel for the distillate. Such setups are used when the distillate forms two phases as distillates, e.g. for water removal during esterification and heterogenous azeotropes. The phase separator permits the adjustment of the interphase and the separate withdrawal of the light and heavy phase. Either the light phase or the heavy phase can be selectively guided back into the vessel or withdrawn.

Vacuum Distillation

DDPS-Diagram-vaccum-Rev1

Additional alternate receivers are integrated, so that the distillate can be taken off during vacuum distillation.

The selected attachment can be equipped with measuring and control devices according to customer’s request and process requirements.

The following measuring instruments are typically included:

  • Thermometer (Pt100) - vapor line
  • Flow meter with local display - distillate flow
  • Pressure gauge with local display - vapor line

Rectification

DDPS-Diagram-rectification-Rev1

Depending on available height and required condensing capacity either tube & shell or coil type heat exchangers are used.

The standard instrumentation covers most applications:

  • 3 Temperature measurements (Pt100) - vapor line entry, vapor line exit, distillate flow
  • Flow measurement - distillate flow
  • Pressure - vapor line
  • Electronic timer for the reflux ratio
