Bubble Column Reactors

Abstract

In this chapter the elementary hydrodynamic characteristics of simple bubble columns are summarized. Different designs of bubble columns are sketched, and

Design, Commissioning, and Performance Assessment of a Lab-Scale Bubble Column Reactor for Photosynthetic Biogas Upgrading with Spirulina platensis

“…Usual operating conditions of high temperature and pressure would not be suitable while using microalgae. Although grid quality biomethane has been achieved, the lower absorption rates of around 0.58 × 10 –4 mol/L/s would thus require a bubble column with higher aspect ratios (the present aspect ratio of 22.5 is significantly higher than aspect ratios of 3–10 usually used in the industry). This requirement of large column heights would not only limit the industrial scale-up of the bubble column but also result in an increased level of oxygen stripping into the upgraded biomethane.…”

Analysis of dispersed multiphase flow using fully-resolved direct numerical simulation: Flow physics and modeling

“…Multiphase gas-liquid flows, in general, and disperse buoyancy-driven flows, in particular, are frequently encountered in the chemical and nuclear industry (Jakobsen, 2008;Anglart and Nylund, 1996;Serizawa et al, 1997). Numerous chemical processes are performed in bubble column reactors, which are vessels filled with liquid reactants, where the gas is fed using a distribution system.…”

“…The objective of this distributor is to create a bubble size distribution that maximizes the bubble surface area. These reactors are typically used in processes where heat and mass transfer phenomena are crucial elements of the process, due to the high exchange efficiency that characterizes these systems (Jakobsen, 2008;Kantarci et al, 2005). Important examples are the Fischer-Tropsch (Haghtalab et al, 2012) process, polymerization reactions, and, oxidation and hydrogenation (Storm and Köpsel, 1992;Ferrer et al, 1985;Debellefontaine and Foussard, 2000) processes.…”
