Raising the coefficient of turbulent diffusion in the reaction zone as means to improve technical and economical parameters of polymer production

Use of a new type of apparatus, high-output small-size tubular turbulent re actors of mainly diffuser-confuser design, in very fast processes, includin g polymerization, is considered. The turbulent diffusion coefficient D-t an d its distribution over the apparatus volume were calculated as functions o f the confuser divergence angle alpha. The calculations were confirmed by e xperimental data. New reactor designs for a number of processes of large-to nnage polymer production were proposed and put into practice.
