Research interests

Dr. Marriott is an experimental thermodynamicist with research interests in high-pressure sour gas properties and applied sulfur chemistry.  His group focuses on optimizing gas conditioning in the presence of H2S, bulk fluid separation by ionic liquids, high-pressure water-hydrocarbon solution chemistry (including hydrates) and fundamental properties of elemental sulfur under industrial conditions.  The research is carried out adjacent to the Alberta Sulphur Research Ltd. laboratories at the University Research Centre (URC) and in many cases complement ASRL’s Core Research Program.
