The article describes and proposes practical use of pinch analysis as one of the methods for optimizing energy consumption at industrial plants. This method allows efficient distribution and utilization of energy flows in technological plants. Pinch analysis of recuperative heat exchangers in heavy resid deasphalting plants is discussed. Solvent deasphalting is one of the most energy-consuming oil refining processes, and primarily energy consumption determines the ultimate cost of deasphalted products, which are a feedstock either for catalytic cracking and hydrocracking plants or a component of lube oil production. Therefore, one of the means of enhancing energy efficiency of these plants is optimization of heat exchanger operation by pinch analysis.

本文描述并提出了将夹点分析作为优化工厂能源消耗的方法之一的实际应用。这种方法允许在技术工厂中有效地分配和利用能量流。讨论了重渣脱沥青厂中换热式换热器的夹点分析。溶剂脱沥青是最耗能的炼油工艺之一，主要是能源消耗决定了脱沥青产品的最终成本，脱沥青产品既是催化裂化和加氢裂化装置的原料，又是润滑油生产的组成部分。因此，提高这些工厂能源效率的方法之一是通过夹点分析优化换热器操作。
