Abstract: A system and methods for power generation uses non-aqueous solvent. The method includes treating oil sands with a non-aqueous solvent to extract bitumen in an extraction process and separating the non-aqueous solvent from the bitumen in a solvent recovery process. The method also includes heating the non-aqueous solvent, expanding the non-aqueous solvent to generate power, and cooling the non-aqueous solvent. The method further includes recycling at least a portion of the non-aqueous solvent to the extraction process.

Abstract: A hydrocarbon processing method, including processing a gaseous hydrocarbon stream to form a first production stream and a first injection stream; and compressing the first injection stream in a compressor placed at a selected location below a surface of a sea; wherein the location of the subsea compressor relative to a nearest inhabited area is determined based on a bubble plume trajectory of a model leak of the first injection stream from the compressor; and wherein the bubble plume trajectory is determined using one or more crossflow momentum parameters is disclosed herein. Also disclosed are hydrocarbon processing facilities having subsea compressors placed at such selected locations, processes for designing such hydrocarbon processing facilities, and a mathematical model useful in such methods, processes, and facilities.

Abstract: The electrodesulfurization of heavy oil feedstreams is accomplished wherein a heavy oil feedstreams, along with hydrogen, is passed the cathode side of an electrochemical cell wherein the organically bound sulfur compounds in the heavy oil are reduced and the sulfur is released as hydrogen sulfide. The hydrogen sulfide can be fed directly into the anode side of the electrochemical cell to produce sulfur and hydrogen or it can be passed to an oxidation zone containing an aqueous solution of an oxidized metal salt.
