Natural gas is an important energy resource, accounting for 29% of the total energy consumed in 2017.1 Natural gas is composed predominantly of methane but it can include other C2 to C5 hydrocarbons such as butane.The primary uses of natural gas are to generate electricity and as feed stock for plastic materials. Natural gas is withdrawn from traditional and hydraulic fracking petroleum wells. The gas obtained from traditional wells generally needs limited purification prior to selling it as a natural gas product. In contrast, wet natural gas withdrawn from wells using hydraulic fracturing requires additional processing to remove the water, other hydrocarbons, and sometimes hydrogen sulfide (H2S) and carbon dioxide (CO2) before it can be sold. Amine gas treatment (also named amine scrubbing, gas sweetening)<br/>typically uses percent concentrations of alkanolamines to remove thesedissolved gases. These neutralizing processes result in dissolved sulfur species, organic acids, amine degradation products, and salt build-up in the amine gas treatment solutions. Determinations of halogenand sulfur-containing compounds in LPG are needed because these contaminants can foul the catalysts during processing and because low halogen content LPG has greater market value. Analysis of LPG hydrocarbons is commonly done by GC-MS; however, the quantification of numerous halogen- and sulfur-containing compounds can be challenging. As with other challenging samples, pyrolytic combustion ion chromatography (CIC) is an ideal approach to eliminate the sample matrix and increase sample homogeneity.
