This unit is design as a pilot scale plant.
The column can be fed at several levels through the SS intermediate plates placed along the column.
The flow transmitters, the temperature sensors and the available pressure indicators, allow the user to monitor the process and to study the influence of the different parameters and the operating conditions.
The DCS and the software application developed for this unit allow parameters variations, process automation and data acquisition in real time and/or historical (extra period).
