Abstract

See full text

The present disclosure provides a process and system for removing at least a portion of organosulfur compounds from an oil sands produced gas and transferring the organosulfur compounds to a bitumen-based liquid. One example of the system includes an absorber to contact the gas with an amount of liquid hydrocarbon sufficient to absorb some of the organosulfur compounds, producing an organosulfur enriched liquid hydrocarbon. The system includes a separator that accepts the organosulfur enriched liquid hydrocarbon and an emulsion that includes water and the bitumen-based liquid. The separator separates produced water from a bitumen-based mixture of organosulfur enriched liquid hydrocarbon and bitumen-based liquid. The system adds an amount of additional liquid hydrocarbon to separate the produced water from the bitumen-based mixture when the amount of liquid hydrocarbon added is less than the amount of liquid hydrocarbon needed to separate the produced water from the bitumen-based mixture.
