Abstract
Methods, processes and devices are described for measuring a volatile content of a process stream that comprises volatile species, such as light hydrocarbons and/or H2S. The method can include introducing a stripping gas into a sample of the process stream to strip the volatiles therefrom and produce a gas phase comprising vaporized volatiles; detecting the vaporized volatiles in the gas phase to obtain a sample volatile content; and determining the volatile content of the process stream based on the sample volatile content. The method and device can be used to measure a light hydrocarbon content of froth treatment tailings in the context of removing such light hydrocarbons prior to flocculating and dewatering the tailings.
