    Abstract: An analysis system for determining one or more operating conditions of a metal electrolysis cell and for facilitating a response is provided. The analysis system comprises a bath probe electrically interconnected to a portable computing device. The bath probe generates signals associated with temperature measurements produced from thermal communication with an electrolysis cell bath. The portable computing device may receive these signals and generate data based thereon. The data may be transformed into operating condition information relating to the electrolysis cell.

    Abstract: Horizontal duct scrubbing systems for removing particulate matter from a gas are disclosed. The horizontal scrubbing systems may receive a particulate-containing gas stream (e.g., containing PM10 and/or PM2.5 particulate matter), and remove at least some of such particulates by spraying liquid droplets co-current to the flow of the gas stream, where the liquid droplets have a volume median droplet diameter (DV0.5) of from 240 microns to 600 microns. The scrubbing system may be substantially free of flow deflection members between a liquid inlet manifold and a demister. The system may be remove at least 50 wt. % PM10 and/or PM2.5 particulate matter from the gas stream.
