The authors of the article consider basic methods of energy saving in energy-intensive processes of chemical and oil refining industries. The reasons for the heat highest consumption when drying wet materials and heat utilization methods limit of the leaving drying agent are explained. All possible energy saving methods which are used for evaporating salt and alkali solutions are listed. Energy saving methods that are applied to distillate binary and multicomponent liquid mixtures are discussed in detail. The energy saving methods in distillation processes based on the reversible distillation theory and on the internal energy saving theory developed by the authors of the article are compared. The higher efficiency of energy saving methods based on the internal energy saving theory in comparison to the reversible distillation is proved. New methods of energy saving are developed based on the internal energy saving theory. It is proved that internal energy saving in distillation columns depends on the reflux ratio in column's rectifying section and on the ratio of the number of theoretical plates in rectifying and stripping sections. The possibility of applying this theory to improve the quality of primary crude oil processing products in complex columns with stripping sections is considered.
