Design and Development of Shell & Tube Heat Exchanger for Beverage

Abstract

In the first part of this paper, a simplified approach to design a Shell & Tube Heat Exchanger [STHE] for beverage and process industry application is presented. The design of STHE includes thermal design and mechanical design. The thermal design of STHE involves evaluation of required effective surface area (<sub>i.e.</sub> number of tubes) and finding out log mean temperature difference [LMTD]. Whereas, the mechanical design includes the design of main shell under internal & external pressure, tube design, baffles design gasket, etc. The design was carried out by referring ASME/TEMA standards, available at the company. The complete design, fabrication, testing and analysis work was carried out at Alfa Laval (India), Ltd., Pune-12. In the second part of this paper detail view of design optimization is presented by flow induced vibration analysis [FVA

Analysis of the performance of the shell and tube heat exchanger: Influence of the baffles and the position of fluid inlet and outlet

“…Shell and tube heat exchangers are a type of recuperative heat exchangers and have a wide representation in the process industry [1,8,9]. They have been used for more than 14 decades, while in the last few decades they have appeared as standardized and standardized constructions.…”

“…Heat exchangers are devices in which heat is exchanged between warmer and colder fluids without a fluids mixture [1,2]. There are several groups and subgroups within the division of heat exchangers.…”

Analysis of the performance of the shell and tube heat exchanger: Influence of pipe layout and diameter

“…The development of industrial needs was accompanied by the development of heat exchangers, so that the basic structural forms were known in the thirties of the last century, when the development of standards in this area began. Heat exchangers are devices in which heat is exchanged between warmer and colder fluids without a fluids mixture [1,2]. In indirect heat exchange, the fluids are separated by a heating surface, on one side of the surface there is one fluid, and on the other side another fluid.…”

Diseño térmico de un intercambiador de calor de tubo y coraza para el enfriamiento de metanol

“…Los ICTC han sido diseñados y/o evaluados por varios autores, que van desde el diseño y evaluación del rendimiento utilizando ANSYS (Dinámica Computacional de Fluido) (Singh y Pal, 2016); la fabricación de ICTC utilizando deflectores helicoidales basados en la metodología de Kern (Harika et al, 2017); el análisis del rendimiento por medio de un método analítico empleado para desarrollar las correlaciones, las cuales fueron insertadas en MATLAB para comprobar luego la idoneidad térmica e hidráulica del equipo diseñado (Ebieto y Eke, 2012); el análisis experimental conteniendo deflectores segmentados a diferentes orientaciones, operando el equipo bajo flujo laminar (Singh y Sehgal, 2013); la evaluación de la influencia de varios parámetros geométricos y de operación sobre el diseño térmico de un ICTC (Sigimon et al, 2015); el análisis térmico extensivo relacionado con la evaluación de la influencia de condiciones severas de carga sobre el rendimiento de un ICTC, utilizando para ello el software ANSYS 14.0 (Dubey et al, 2014); el diseño patentado de un ICTC equipado con minijets y con construcción cilíndrica (Wajs et al, 2019); el estudio del incremento de la transferencia de calor a partir de la mejora de la configuración de un ICTC considerando tanto el espaciado como el corte de los deflectores (Yousufuddin, 2018); y por último el diseño tanto térmico como mecánico de un ICTC para la industria de bebidas por medio de un método simplificado (Gawande et al, 2012).…”
