Sparged gas
Web22. feb 2016 · The gas is bubbled up through the liquid in a sparged reactor. For smaller bubbles, a porous pipe diffuser can be used instead (Towler, 2012). The designer must allow some disengaging space at the top of the reactor, or entrainment will be excessive. If the gas flow rate is large then the gas flow can be used as the primary means of agitation. Web1. sep 2012 · Sparging refers to the process of injecting a gas through a diffuser into a liquid phase. It is used in both physical and chemical process applications. In physical process applications, the gas is used to either …

Web1. okt 2024 · The aspect ratio (vertical straight-side height divided by diameter) is usually between 1:1 to 1.5:1. Taller vessels, with aspect ratios ranging to about 4:1, are used when necessary to maximise heat transfer through a jacket, to maximise contact time of a sparged gas, or for other process requirements. WebSparging (chemistry), a process in which a gas is bubbled through a liquid to remove other gases or volatile compounds Air sparging, a remediation process in which air is pushed through contaminated water or soil to remove volatile pollutants
Web16. aug 2024 · As shown in a small-scale laboratory experiment, when a sparge gas is introduced in a groundwater treatment zone, PFAS will collect at the air-groundwater interfaces and be drawn upwards by the buoyancy of the sparged gas. The sparging results in lower PFAS concentrations in the deeper portions of the sparged zone, remediating this … Web22. aug 2024 · August 22, 2024. Sparging, a mass transfer process between a gas and a liquid, is commonly encountered in industrial applications such as beverage carbonation and photobioreactors, or even at home for aeration in aquariums. In this blog post, we detail how to model a type of sparging, carbonation, using the COMSOL Multiphysics® software.
