The application of integrated cold and hot condensers in distillation technologyDistillation is a unit operation used for separating liquid mixtures, capable of separating a variety of substances, particularly finding extensive applications in the purification of electronic-grade chemicals. This article provides an overview of the principles and experimental procedures of distillation technology, its applications in the preparation of electronic chemicals, and the ideas for energy-saving optimization. Keywords: Distillation, Experimental Principles, Electronic Chemicals, Energy-saving OptimizationElectronic chemicals can be obtained through the purification of industrial chemicals, making separation and purification a critical step in acquiring electronic-grade chemicals. Common separation and purification techniques include distillation, adsorption, crystallization, and extraction, among which distillation stands out for its high separation efficiency, high product purity, large processing capacity, strong controllability, wide applicability, and ease of engineering. It is a commonly used and key technology for the purification of electronic chemicals. However, the design of the distillation separation process for electronic chemicals still primarily relies on experience. Additionally, the operation steps for distillation are complex, energy consumption is high, and energy utilization is low, thus, conducting research on energy-saving technologies holds significant importance.
