Solvent Recovery Distillation System
Solvent Recovery Unit with Concentric-Tube-Column.
PILODIST 107 is an easy to handele solvent recovery system for extremely pure solvents.
The solvent mixtures are side products of extraction’s, washing processes, chemical and biochemical reactions, chromatographic operations in clinical range, especially in anatomical and pathological institutes.
The system is equipped with a concentric-tube-column, i.e. highest separation efficiency and high load ranges.
The system can alternatively be equipped with 3 different types of distillation columns with the following characteristics:
1. Concentric-tube-column, using no packing
low distillation rate of approx. 3...6 mL/min.
highest separation efficiency of up to 60 theor. Plates
very low pressure drop
all-glass static distillation clumn without any packing
1. Glass distillation column packed with wire mesh packing
distillation rate 10...30 mL/min.
high separation efficiency up to 30 theor. Plates
low pressure drop
wire mesh packing stainless steel (1.4571/AISI 316Ti)
2. Glass distillation column packed with Raschig rings
distillation rate 10...30 mL/min.
separation efficiency up to 15 theor. Plates
mid pressure drop
all glass column with glass Raschig rings
see additional accessories in option 1
Application:
All kind of solvents like acetone, DMF, THF, parrafins,Xylenes, alcohol’s, acetonitriles, isooctane, hexane, methyl chloride and other HPLC-solvents.

2 Distillate receiver
1 l with adapter piece for connection to the distillate line and ventilation, located on the outer side of the cabinet in a safety cover
1 Distillation control Device DCD4001.
Computer-controlled Device for PILODIST Distillation systems with all necessary and peripheral components.
Contains the operation and control elements for all parameters like Temperature, Vacuum, Reflux Divider, Limit and Alarm system, Fraction collector.
The actual parameters can be displayed in graphical curves to inform the operator about the actual status. The set Parameters can be saved as recipes and reloaded.
The control system is based on a multifunctional serial bus system, connected to a PC with our new and most modern windows based operation software.
The Distillation control Device comes along complete with all operation software, PC and Interface box as central connection point for all sensors.
