Abstract
The authors carried out calculations to increase resource efficiency, energy saving of oil refining processes (cracking, reforming, isomerization) by mathematical modeling with an increase in the depth of oil refining, taking into account the composition of the processed raw materials. This article presents the results of calculations for optimizing existing installations under real technological conditions of one oil refinery. The results of calculations can be implemented in production. The authors have developed universal modeling programs that can be used to increase the resource efficiency of a catalytic cracking, reforming and isomerization plant, predict the group hydrocarbon composition of the flow after the reactor (in the last two processes), the output of products from the plant, the group composition and octane number of gasoline, as well as determine the optimal operating mode of the reactor.
