I have 35 years of experience, and specialize in the field of gas separations, especially natural gas related matters with specific knowledge in the areas of small-scale sulfur removal technology such as scavengers and liquid reduction-oxidation reaction (redox) processes, as well as natural gas dehydration, and natural gas liquid removal. I have published on such topics as sulfur recovery, liquid reduction-oxidation reaction (redox), H2S and CO2 removal using physical solvents, scavengers for H2S removal, and coal gasification.
