Optimization of the heat exchange system of the gasoline fraction hydrotreating unit

Abstract

This article deals with the main trends of improving the energy efficiency of production facilities for processing hydrocarbon materials on the example of a catalytic reforming unit. By analyzing the heat-technological scheme of the hydrotreatment section, the potential for energy saving has been identified and options for upgrading the heat exchange system of the stabilization unit to increase the use of secondary energy resources and minimize heat losses have been proposed. Based on thermal and economic calculations, a more efficient option has been chosen with an arrangement of multistage heat exchange and use of distillate product for preheating raw materials, which allows more fully using the potential of its own streams. The proposed optimization of the heat exchange system of the stabilization unit of the hydrotreating plant by involving the distillate product in the heat exchange will provide an increase in the degree of heat recovery with a reduction in heat losses and electricity consumption, a reduction in the number of heat exchange equipment units and a more rational use of them.
