Abstract

Unit Operations Lab Bazaar: Assessment of Miniature Industrial EquipmentThere is a need for lower cost undergraduate Unit Operations equipment to meet needs atbudget constrained colleges and universities, and industrial technology programs. Thereis a further need to reduce the space in which equipment is housed and to design flexiblesystems that can perform more than one task, especially for emerging Departments or incountries where Departments must rent space from the Universities. At our Universitywe have developed a way to meet these needs by providing miniaturized low-costindustrial equipment on the size order of a dollar bill and in the form of interchangeablecartridges. Clear plastic casing allows students to “uncover” the fluid flow arrangementand meaning behind the various pitches, tubes sizes, spacings, turns and basic geometrythat encompass typical equipment and are used in mathematical modeling of suchsystems. Our cartridges snap into a base desktop sized module unit that contains fluidreservoirs, flow meters and temperature and pressure readouts.In this paper we focus in particular on one type of miniaturized unit, the traditional heatexchanger. A challenge with miniaturization is how flow profiles will affect pressuredrops and heat transfer coefficients. While reliable correlations exist for pilot andindustrial scale equipment, we need to know whether, for smaller geometries, analyseswill be impacted by issues such as underdevelopment of flow profiles due to short tubelengths, or exorbitant heat and friction losses occur because of un-insulated surfaces andlarge surface area to volume ratios. Herein, we present an assessment of a very smallscale shell and tube heat exchanger. We show times to steady state on the order of 10 –20 sec, which are actually superior to those of larger units, that pressure drop calculationsare in reasonable alignment with actual measured values, and that heat transfercorrelations at least offer reasonable agreement with experimental values. We addstudent responses on how they learn about common industrial processes when using the“see through” miniaturized systems as opposed to larger pilot scale units.
