Heat-exchange equipment of various types makes up a significant part of technological apparatuses in the gas and petrochemical industries.This is explained by the fact that almost all Pregnancy Tests technological processes in the refining and petrochemical industries (heating, rectification, drying, evaporation, etc.) are associated, one way or another, with the need to supply or remove heat.

The purpose of this work is to analyze the heat exchange apparatuses used in petrochemistry, to compile a methodology for calculating heat exchange apparatuses, to review existing mathematical models of heat exchange processes, and to formulate the corresponding boundary value problems, and to develop a mathematical model that allows us to calculate the temperature profiles when fuel oil is heated with water vapor in a single-pass tubular heat exchanger along the length of the heat exchange apparatus.Within the framework of the conducted research mathematical models of the thermal field at heating of fuel oil with water steam in a single-pass tubular heat exchanger depending on the design, geometric dimensions and operating conditions of the heat exchanger were created and realized.The proposed mathematical models can be used to select the optimal parameters of the heat exchanger and the optimal fuel oil pumping rate in the heat exchanger, which will provide a sufficiently high heat transfer coefficient and Fireguard not too high head losses.
