Characterization of a Reverse Jet Scrubber for gas/liquid absorption

The Reverse Jet Scrubber (RJS) is a versatile pollution control device that efficiently removes particulates and contaminant gases from industrial gas streams. It operates with either a liquid solution or finely suspended solids, handling high-flow gas streams with varying particle concentrations. Despite its promise, knowledge of RJS design and performance remains scarce, and design criteria are proprietary to the companies marketing the technology. This paper presents an experimental setup designed to characterize the device. In this investigation, gas pressure drop measurements across the liquid jet were used as a metric to define the operating parameters of the RJS. Additionally, absorption tests with two volatile organic compounds measured the mass transfer capabilities, with efficiency and overall mass transfer coefficient quantified at various gas and liquid flow rates. These results provide a valuable preliminary experimental data set necessary for the future development and validation of mechanistic design models for mass transfer.
