At present, the problem of saving energy resources is more relevant than ever. The largest consumers of these resources are industrial enterprises, institutions and organizations, all of which are interested in the efficient use of electricity, heat, water and other resources. One of the key criteria for the effectiveness of any industrial production is its energy efficiency. Increasing energy efficiency is an essential factor for their optimal operation. Distillation plants are among such facilities. One of the important directions for improving their energy efficiency is the enhancement of automatic control systems for such units. Modern approaches to the improvement of automatic control systems include: the application of intelligent control algorithms, adaptive and predictive regulation systems, the use of more accurate and energy-efficient peripheral equipment, the application of various software optimization methods in the calculation of mathematical models of objects, advanced diagnostic techniques and the design of facilities considering energy-saving criteria, among many others. Even within each method or technique, there is a wide range of possible implementation approaches. This paper provides a review of literature sources related to the improvement of distillation systems according to energy-saving criteria, their analysis and structuring, as well as the formulation of general approaches to possible solutions for enhancing modern automation systems.
