Continuously working distillation system

This system, made of high quality borosilicate glassware 3.3, is for universal operation under atmospheric or vacuum conditions.

The customized system consists of 2 distillation columns in the size of DN 50 with silvered high-vacuum mantle, packed with high efficient SULZER-packing to ensure a high separation efficiency. The system can alternatively also be equipped with different column packing material depending on application.

PILODIST 250 BB is equipped with a fully continuous balance system for all receiver vessels (feed, distillate, bottom product) to allow a fully-automatic mass balance during the distillation process. The transfer of the product into and out of the distillation process is being realized via a hermetically sealed pump so that product take-off and product charge is continuously possible even under vacuum condition. This allows a fully-continuous operation without any limitation due to the volume of the receivers. The distillate as well as the bottom product can be traced back automatically into the feed vessel to raise and optimize the operation of the distillation and to achieve the desired distillate product without losing feed product or any contamination of the final product.

As a safety feature the circulation evaporator is equipped with a dry-up rotection. The individual and fully-automatic PILODIST – control system provides an automatic control of the temperature of the column heating mantles depending on the head temperature or the column-middle-temperature respectively to ensure a fully-adiabatically operation.

The high efficient condenser, made of glass, detects automatically the temperature of the cooling water at the point of entering and leaving the condenser. A continuous measurement and control of the differential pressure between head and bottom of the system is being realized for the detection and control of the column load.

The very user friendly PILODIST process control system (IP65) can be remotely controlled and includes a visualized user interface.
