One particular characteristic of shale gas is its varying composition. Shale gas composition depends heavily on the location of the sources, and it may variate even within wells in the same play. The primary component of shale gas is methane, but it also contains considerable quantities of natural gas liquids (NGLs) such as ethane and propane. Apart from these components, shale gas also contains acid gases such as CO₂, H₂S, and inorganic components such as nitrogen [5,14]. The separation of NGLs from methane has induced industries to look for alternatives to transform them into more valuable products, but at the same time the varying composition of shale gas represents a challenge for the treatment plants, which have to be robustly designed to handle such variations in the gas composition.
