DESTSENS for on-line alcohol analysis in rectification and distillation processes
Frings has developed a distillery waste management tool to optimize the rectification/distillation process.
The DESTSENS has proved to be a particularly suitable measuring system for the production of alcohol based on corn, cereals, molasses and other biogenic raw materials. Benefits of the Destsens include increased alcohol recovery and reduced energy consumption.
The exact knowledge of the actual residual alcohol concentration from the column has several economic advantages:
Optimization of the column control
Reduction of energy consumption
Improved raw material utilization
The DESTSENS determines the residual ethanol content in the slop in the range of 0.01-0.6% v/v. A constant slop temperature is adjusted by means of a heat exchanger. The residual ethanol level is visually displayed and an analog control signal is provided for process control.

Operating principle of the probe:
The alcohol measuring system Alcosens 2620 allows for a safe and precise online control of production processes requiring the determination of alcohol concentrations in aqueous solutions. The probe is immersed directly into the production liquid, the alcohol flows through a membrane into a carrier gas and is led to a semi-conductor sensor where it is measured and recorded. At the same time the process temperature is measured. Both functions are linked mathematically, and a digital evaluation system displays the signals corresponding to the actual alcohol concentration. The Alcosens is a reliable system for measuring alcohol concentrations in a temperature range from 20°C (68F) and 143°C (289F). During CIP the probe can remain installed, without being damaged.
