Abstract
The intensification of mixing processes is considered when dissolving solid granular alkali (caustic soda) in hydrazine hydrate by applying the method of resonance-pulsating action to mix the reacting mass. The results of experimental studies are described, on the basis of which a method for calculating the process of dissolution of alkali in hydrazine hydrate is developed. The method allows estimating the mass transfer coefficient. The obtained results are consistent with published data. The design of a pulsating reactor for carrying out the dissolution process was proposed based on the analysis of the results of experimental and industrial tests. The described method can significantly reduce the cost of energy for mixing, in addition ensuring almost complete tightness of the reactor, and, hence, its reliability when working with potentially dangerous reagents and products.
