Modeling of the Temperature Profile When Heating Fuel Oil with Water Vapor in a Single-Pass Tubular Heat Exchanger

Heat exchange equipment of various types makes up a significant part of technological equipment in the gas and petrochemical industries. This is explained by the fact that almost all technological processes in the oil refining and petrochemical industries (heating, rectification, drying, evaporation, etc.) are connected, in one way or another, with the need to supply or remove heat. The purpose of this work is to analyze heat exchangers used in petrochemistry, develop a methodology for calculating heat exchangers, review existing mathematical models of heat exchange processes and formulate corresponding boundary value problems, develop a mathematical model that allows calculating temperature profiles at heating fuel oil with water vapor in a single-pass tubular heat exchanger along the length of the heat exchanger. As part of the research, mathematical models of the thermal field were created and implemented at heating fuel oil with water vapor in a single-pass tubular heat exchanger, depending on the design, geometric sizes, and operating conditions of the heat exchanger. The proposed mathematical models can be used to select the optimal parameters of the heat exchanger and the optimal rate of pumping fuel oil in the heat exchanger, which will ensure a sufficiently high heat transfer coefficient and not too large pressure losses.
