Abstract

. The goal of this work is to identify the best alternatives that allow for improving the thermal efficiency of a shell and tube heat exchanger in real operating conditions. The main motivation for carrying out the research is based on the need identified, together with the oil, natural gas, and alternative energy industry, to analyze and learn about the main criteria that directly impact the thermal efficiency of a heat exchanger. The applied methodology was based on the AHP (Analytic Hierarchy Process) multicriteria method. Three relevant criteria were identified: Thermodynamic, Hydrodynamic, and Economic. Additionally, a complete analysis of 9 sub-criteria (i.e. energy and exergetic analysis of the process, analysis of the thermodynamic properties of the fluids; pressure drop, volumetric flow of hot and cold fluids; energy costs, maintenance, operation and geometry of the heat exchanger) allowed us to conclude that the best strategy to increase the thermal efficiency of a heat exchanger in real operating conditions consists of using innovative online cleaning prototypes that use abrasive spheres. This will allow the heat exchanger to be cleaned simultaneously with its operation, reducing downtime and maintenance times/costs.

用AHP多准则法分析管壳式换热器的热力和流体动力性能

。这项工作的目标是确定在实际操作条件下，能够提高管壳式热交换器热效率的最佳替代方案。开展这项研究的主要动机是基于确定的需求，以及石油、天然气和替代能源行业，分析和了解直接影响热交换器热效率的主要标准。应用的方法是基于AHP(层次分析法)多准则法。确定了三个相关标准:热力学、流体力学和经济。此外，9个子标准的完整分析(即过程的能量和火用分析，流体的热力学性质分析;冷热流体的压降、体积流量;能源成本、维护、操作和热交换器的几何形状)使我们得出结论，在实际操作条件下，提高热交换器热效率的最佳策略是使用创新的在线清洁原型，使用研磨球。这将允许热交换器在运行的同时进行清洁，减少停机时间和维护时间/成本。
