Process vessels in the ethanol plant

Overview

To ensure the best possible fermentation of the ingeredients, optimal process conditions must prevail, control of pH value and temperature of the medium play important roles. The pH is adjusted by adding acids or alkalis, and sodium hydroxide is used to clean the vessel under absolute sanitary conditions. The levels of the process vessels have to be monitored at all times, to ensure continuous operation of the system. The measured media place very high demands on the chemical resistance of the sensors. To be totally reliable, the instruments need to be equally resistant to both acids and alkalis.
