STTS Continues Webinar Series With CFD in Gas Scrubber Redesign

The SPE Separations Technology Technical Section (STTS) will continue its webinar series on gas scrubber design with a presentation on the effectiveness of computational fluid dynamics (CFD) in guiding the redesign of a scrubber inlet.

The webinar, titled “CFD Optimization of Scrubber Inlet Design,” will be presented on 8 October by Lee Rhyne, a research consultant in flow assurance at Chevron.

Rhyne will use CFD to study several typical scrubber inlet devices, such as the angled baffle plate for induced swirl, the V-baffle for momentum breaking, and the inlet vane distributor for uniform gas distribution. At least one example of step-by-step incremental redesign will be shown, in which there could be no welding on the vessel, that resulted in a several-fold improvement in the predicted performance of a scrubber inlet.

In addition, a methodology and evaluation criteria for scrubber inlets that can be generally applied to a wide variety of scrubber applications will be explained.

The webinar will focus on scrubber design and engineering methods rather than the intricacies of setting up and running CFD.
