Dr. Dowling has over 27 years experience with ASRL specializing in corrosion, high temperature Claus furnace and catalytic stage chemistry and plant modeling. He has over 50 publications in these areas and is a recipient of the CGPA William Rea Memorial Award. He is responsible for high temperature and corrosion related projects.
Research Scientist
and Project Manager:
Dr. Alex Primak
Before joining ASRL in 2010, Dr. Alex Primak has worked in a variety of fields including kilo-scale organic synthesis and R&D of direct methanol fuel cells. He is responsible for research related to H2S scavengers for sour gas/oil streams. In addition to this, he is also involved in bitumen upgrading, the kinetics of the gas-phase reaction of H2S with oxygen, the kinetics of the oxidation of ethanolamines, and studies on the use of sulfuric acid/sulfur in the hydrometallurgical extraction of metals such as nickel, cobalt and uranium from their ores.

Dr. Marriott is an experimental thermodynamicist with research interests in high pressure sour gas properties and sulfur chemistry. His group focuses on optimizing gas conditioning in the presence of H2S, bulk fluid separation by ionic liquids, water hydrocarbon mixture chemistry (including hydrates) and fundamental properties of elemental sulfur under industrial conditions. Research is carried out through an IRC program in the Department of the Chemistry and is sponsored by the Natural Science and Engineering Council of Canada, ExxonMobil Upstream Research Co., Husky Oil Operations Ltd., Shell Canada Ltd., Suncor Energy Ltd., Total E&P Canada Ltd., the University of Calgary and Alberta Sulphur Research Ltd. Projects are carried out in collaboration with ASRL researchers at the University Research Centre and in many cases compliment and augment the Core Research Program. Prior to taking his faculty position, he spent 8 years with ASRL as a Research Scientist and Project Manager with interests in understanding elemental sulfur deposition during the production of sour gas, sulfur solvent properties, water content for acid gas mixtures, sulfur degassing mechanisms, reservoir mineral interactions, and pVT properties for SO2 and H2S mixtures.
