    Borosilicate glass columns have been used successfully for many years in the field of distillation operations mainly for the benefits of its anti-corrosive and transparent material of construction.  They are normally filled with packing materials made of borosilicate glass, but other packing materials can also be supplied.  Cooling arrangements for the distillate can use either shell and tube or coil type heat exchangers.

    Features

    • Diameters from 3" (80 mm) to 40" (1000 mm)
    • Heights up to 100 ft (30 meters)
    • Operates at atmospheric pressure or at high vacuum

     

    Additional options / components

    • Durapack - a structured glass packing with outstanding separation properties, ideal for processes that require no metal.
    • Core-Tray support - provides a solution for the problem of metal-free support trays with a large free cross-section of 120%. (Liquid feeds based on the same Core-Tray design principle are also available).
    • Liquid collectors
    • Redistributors
    • Automatic control system
    • Reboiler vessels
    • Condensers / Boilers / Coolers  
    • Reflux separators and timers
    • Various types of packing

    Overheads for Reactor Systems

    Overhead components can be integrated with your reactor (or other type of vessel) to create a system that can efficiently carry out reaction, distillation, and other process functionalities.  De Dietrich glass and glass-lined steel columns can both be incorporated with a process vessel to handle multiple unit operations within a single system.

    Overhead-reactor-image-2-ddps

    Distillation top with shell and tube heat exchanger and external reflux separator for vessels above 630 liters.
    DDPS-Diagram-vaccum-distillation

    Falling condensation in the vacuum with receivers.
    DDPS-Diagram-rectification-Rev1

    Distillation columns with controlled reflux condition for concentration with random packing or DURAPACK.

    DDPS-Diagram-distillation-HE-Rev1

    Distillation top with phase separator for azeotrope mixture. Optional interconnection of phases.
