Thus, knowing the composition of raw materials (PP-I-16), composition of the wastestream ( x ), and mass ratio of recycling ( ϕ ), we can calculate the composition of the4iraw materials entering the reactors of dehydrogenation ( x ) and hydrogenation ( x ).The calculation results are shown in fig. 2.x 0i1i3iOlefines output, kg/ t. of freshmaterial700600500400300200100635,1422,9316,8253,1124,9 139,2 157,2 180,1 210,60 0,1 0,2 0,3 0,4 0,5 0,6 0,7 0,8Flow ratioFig. 2 - Dependence of olefins yield perton of fresh material on the ratio of flowsThe presented dependence shows that the recycling ratio equal to 0.3 is the best,as an increase in the yield of olefins is 55.2 kg per ton of fresh material (44%), whilean increase in diolefines output is 1,8 kg per ton of fresh raw material (72%).The model developed and programs created on its basis would be applied assimulators and expert systems for engineering and technical personnel of the plant.The software product allows to calculate the characteristics of the currentprocess, which can not be identified by laboratory testing or on the current instrumentreadings. Also, using the simulation program can predict the results of changes intechnological regime and reconstruction of the existing installation.Total revenue from the introduction of simulation program will be about 225thousand rubles per day. As results of researches certificates of state registration ofcomputer programs were received.References:[1]. Kravysov A.V., Ivashkina E.N., Yuriev E.M., Ivanchina E.D.
