This working, reduced-scale, manually-operated, bench-top distillation demonstrator and training aid, provides for an in-depth, hands-on understanding of the basic distillation process. The device allows the student to experience and operate a continuous distillation process and modify the variables upon which it is based. The product depicts the dynamic behavior of a distillation column with bubble-cap trays as it is operated by the instructor and/or a student. Methanol or ethanol, in reduction, is used as the primary medium, based on their well-known physical properties and safety considerations.

A variety of additional safeguards are provided to avert the possibility of unwanted ignition, or exposure to vapors. Two, u-tube pressure suppression systems are designed so that the unit cannot be over pressurized and to prevent unintentional vapor loss to the atmosphere. A heat protection device is located at the top of the reboiler activating a relay to provide an automatic temperature shut off in the event of overheating. An industrial grade control panel with emergency safety disconnect and provision for lock-out/tag-out is also provided.

The training aid incorporates a glass 50 mm diameter distillation column with 10 bubble-cap trays, glass reboiler and associated glass condensate and chilled water heat exchangers which enhance the visual experience of the distillation process under continuous operation.

The system includes a 7" touch-screen HMI operator control and measurement package. Trending and process variable data, can be captured using a USB interface.
1-1/2" x 1-1/2" tubular stainless steel structure system with aluminum connection components.
Custom, blown-glass, 50mm ID distillation column with ten bubble-cap trays.
