A prototype natural gas compressor based on the Taylor cycle is investigated as a viable alternative to traditional multi-stage reciprocating compressors. In the current embodiment, an emulsion of natural gas and water are introduced into a rotating, centrifugal compressor. Our research addresses the interactions of the bubbles of natural gas with the water solvent and the chemistry of dissolution and any fouling reactions that might result. A common contaminant in natural gas is hydrogen sulfide, which can react with water to form sulfates and sulfuric acid. In addition, these byproducts can react with dust and debris in the pipeline to create corrosive and gumming agents. To examine these effects, we designed and performed a model experiment, in which we synthesized hydrogen sulfide, dissolved it in water, and detected the products of dissolution via gas chromatography-mass spectrometry.
