Abstract: Extended abstract. In this master’s thesis, a model of a heat exchanger has been developed to assess the thermal regime of heating the extractant, which is included in the process of extracting the target component from the ozokerite ore of the Boryslav deposit. The master’s work describes aspects of the production and practical application of ozokerite ore, provides an overview and selection of software for the task. The work additionally contains a section on economic analysis. There are pages, tables, __ figures, applications. The list of references is 15 titles. The object of the research is a heat exchanger for heating gasoline on the technological line for extracting ozokerite from ozokerite ore The subject of research is the process of heat exchange of working media "gasoline - water steam". The purpose of the research is computer modeling of the process of heat exchange of working media. The model was developed using SolidWorks Flow Simulation tools, SolidWorks software, which is used to simulate the process of motion of liquids and gases. The finished model is shown in picture 1. Fig. 1. Creating a heat exchanger assembly "pipe in pipe" (arrays of elements). The model was developed using SolidWorks Flow Simulation tools, the SolidWorks software package, which is used to simulate the process of movement of liquids and gases. The necessary data are entered into the created project for the calculation, after which the internal problem of heat transfer is selected and the thermal conductivity in solids is indicated. Gravity is taken into account to improve calculations. On the basis of the average heat transfer temperature, data is entered for the solvent. Boundary conditions are set for calculating heat transfer in the apparatus, that is, the thermodynamic parameters of the flows and their consumption. After that, two global tasks are set to perform the calculation: the average temperature of flows and a solid. The proposed computational model allows obtaining results for evaluating the temperature distribution on the walls of the heat exchanger (fig 1.1) and determining the temperatures of flows at the outlet of the media (fig 1.2) using Surface Parameters (Surface parameters). The data obtained in the course of computer simulation are in good agreement with the results of the pilot operation. Fig. 1.1. Temperature distribution on the walls of the heat exchanger Fig. 1.2.
