Abstract

Based on the current state of the resource base and the country’s growing needs for oil and gas

resources, the introduction of modern technologies for maintaining and intensifying oil and gas

production and processing, the priority is to increase the energy efficiency of the fuel and energy complex.

In this direction, a mathematical model of the process of thermal preparation of an oil-gas-condensate

mixture for distillation has been developed, which makes it possible to determine the energetically

optimal heat exchange surface of the apparatus, and the main results of calculations for determining the

optimal lengths of heat transfer pipes are presented. The article is devoted to the development of a

methodology for optimal calculation and design of devices for thermal preparation (heating) of

hydrocarbon raw materials for primary distillation based on system analysis and mathematical modeling of

this process. The objective function of the optimality criterion is formulated in the form of a system of equations. The method for calculating the heat transfer surface of tubular heat exchange devices for preheating hydrocarbons, based on the analysis of the temperature distribution curves of crude oil along the length of the tube bundle of the devices, helps to identify the reserve for increasing the thermal power of the devices at a given performance or the degree of possible reduction in the heat transfer surface in stage of their design. One of the recommendations for increasing the efficiency of operating heat exchangers is to increase their productivity, which leads to an average increase in the length of the active section of heating the raw materials in the tubes by a factor of two.
