Course Credit: 0.15 CEU, 1.5 PDH

Over the years, a variety of scrubber inlets have been devised by engineers. Those designs attempt to uniformly distribute the flow, maximize liquid capture, and reduce liquid re-entrainment. In many cases, the designs are based on engineering intuition. Some testing of these designs has been done, mostly with air-water flows, and then implemented across a wide range of flow rates and fluid properties. Unfortunately, the industry has seen evidence of scrubber mal-performance too many times using traditional design approaches. We now have better tools.

The purpose of this webinar is to illustrate the effectiveness of Computational Fluid Dynamics (CFD) in guiding re-design of a scrubber inlet within the constraints of the project team. This webinar will use CFD to look at several typical scrubber inlet devices such as the angled baffle plate to induce 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 re-design will be shown where there could be no welding on the vessel and yet the predicted performance of the scrubber inlet was improved several-fold. A methodology and evaluation criteria for scrubber inlets will be explained that can be generally applied to a wide variety of scrubber applications. This webinar focuses on scrubber design and engineering methods, rather than the intricacies of setting up and running CFD.
