Use of a rotor-pulsation apparatus to increase the efficiency of the oxygen absorption process in aqueous solutions
(2024) Obodovych, Oleksandr; Bulii, Yurii; Pereiaslavtseva, Olesia; Stepanova, Olena
Experimental studies of the process of oxygen absorption in aqueous solutions using a rotary-pulsation apparatus (RPA), which implements the method of discrete-pulse energy input, have been carried out. As a result of research, the values of the parameters characterizing the efficiency of aeration, namely the oxidizing capacity of aeration for different modes of operation of the dispersant-mixer, were obtained. The high efficiency of using RPA has been proven in comparison with some aeration devices

It is proved expedient to supply to the impurity concentration column of alcohol-containing fractions in the form of non-condensed steam in the deflegmators of the main columns in the amount of 5%. This solution allows to reduce the heating steam consumption from 10 to 8.8 kg/dal of anhydrous alcohol. The expected profit for the plant with a capacity of 3000 dal of alcohol per day will be about 2 million UAH per year
