Управление непрерывными технологическими процессами в нефтепереработке на примере каталитического риформинга при неопределенности

Abstract

Using the example of catalytic reforming, a scientific description of the task of managing continuous techno-logical processes in oil refining under uncertainty has been performed and an appropriate management approach has been developed. It is proposed to take into account the influence of disturbances in the systems of automatic control of parameters (temperature, level, flow and pressure) in the unit for stabilizing the catalysate in the catalytic reforming unit. These parameters are important characteristics of the catalysate stabilization unit, whose indicators characterize the quality of functioning of the entire catalytic reforming complex. The problem of control for continuous technological processes in oil refining is solved using the example of catalytic reforming under uncertainty by solving the following tasks: development of a procedure and selection of methods for optimizing these processes; development of optimization algorithms for these processes; application of an optimization algorithm for these processes in order to calculate optimal control values; ensuring the stability of automatic control systems (stabilization) of the parameters of these processes. The management of these processes consists in finding optimal controls that contribute to achieving a minimum of a single criterion of op-timality, taking into account disturbances and constraints. The development of a control system for catalytic reforming provides a more efficient control option for catalytic reforming with the most important positive effects: a decrease in the average annual organizational costs for the technological process by 86.74 million rubles. with no increase in the octane number for gasoline produced, an increase in the average octane number for gasoline produced by 1.1 with no decrease in the amount of organizational costs for the technological process.
