The most important parameters necessary for the precise control of the separation of monoethanolamine, diethanolamine, and triethanolamine on column distillation apparatus are their initial concentrations in the mixtures fed to the columns. Currently, the use of a solid-state optical sensor, which makes it possible to determine the desired ratio in a mode close to the real-time regime. The technical parameters for the sensitivity and speed achieved by the sensor are determined in the determination of monoethanolamine, diethanolamine, and triethanolamine, as well as the sensor parameters and conditions of use, which enable the sensor to effectively solve the tasks. In particular, the concentration of the mixture of analytes in the sensor chamber is 500 mg / m3, the thickness of the sensitive coating is about 0.5 μm, the operating temperature is 45÷50 ° C, the time for one cycle of measuring the diethanolamine/triethanolamine ratio is 150 ÷ 180 seconds.
