Introduction: The solution having to be distilled, stored in a glass tank, is sent to the distillation column by a metering pump after crossing a pre-heating exchanger. The column can be fed through 3 points at different height. The distillation column is completely made of glass and it consists of a reboiler, of a column with packing of steel mesh and of a condenser with reflux valve and head. The bottom product and the distillate are collected into two glass tanks after being cooled by two heat exchangers.
