Abstract
As an important separation technology in the chemical field, the distillation process occupies a large proportion in the energy consumption, so it is of great significance to study the energy integration and optimization strategies. This study aims to systematically analyze the energy distribution and utilization during distillation, and propose effective energy integration and optimization strategies to reduce energy consumption and improve efficiency. For this purpose, the method of combining theoretical analysis and experimental research is adopted to establish the energy model of distillation process to accurately describe the transfer relationship between material and energy; then introduce advanced mathematical optimization algorithm to solve the model, determine the optimal combination of operation parameters, and consider practical factors such as equipment constraints and process requirements. The results show that the proposed optimization strategy can significantly reduce the heat load of the reboiler and condenser, realize the effective heat recovery and reuse of heat, reduce the overall energy consumption by about 20%, and keep the product purity at a high level.
