Краткое описание

Physical and mathematical models, which describe the processes of mass and heat transfer in neutralization apparatus, are developed with the usage of theory of rheological transitions. The system of stabilization of flows correlation of nitric acid and ammonia was enhanced using introduction of the corrective signal according to the coefficient of the ratio of time constants of mass transfer into the control algorithm for the ratio of these flows. We proposed control system for temperature mode of neutralization apparatus by the difference of temperatures in the reaction zone and output from neutralization apparatus using insertion of steam into the reaction zone.
