Fractionating Tower with Integrated Heat Transfer

Abstract

The subject of the present study is a tubular fractionating tower in which the heat exchange pipes and the intertubular space together function as contact devices, while the process of fractionation itself occurs in the film mode; the tubular space fulfills the functions of a stripping section, while the intertubular space serves as a rectifying section and condenser for use in the formation of distillate. As a result of mass transfer, the steam phase is enriched with low-boiling components and the liquid phase with high-boiling components. The study is designed to develop methods of calculating and simulating processes in a fractionating tower with integrated heat exchange. Through the use of the results of the study, the energy consumption and metal content of the equipment may both be reduced.
