摘要

This article presents a comprehensive analysis of both established and emerging technologies for enhancing the degree of heat recovery in atmospheric and vacuum distillation units. The methods of pinch-based heat exchanger network optimization, application of condenser-evaporators in fractionation columns, utilization of waste heat from furnace flue gases, integration of various types of heat pumps, and the use of thermal energy storage systems are considered with a focus on their operating principles, application areas, limitations, economic performance, and implementation challenges. Particular attention is paid to the synergistic effects of combining methods and the necessity of a systems approach when designing and modernizing atmospheric and vacuum distillation units. The energy-saving potential and economic efficiency of these methods are calculated.
