In the operation of natural gas pipelines, a blockage or leak can cause expensive production losses, damage equipment and pose safety hazards. When water (H2O) is present, gas hydrates can form, creating an icy plug in natural gas mixtures, especially at low temperatures and high pressures. When H2O, carbon dioxide (CO2) and hydrogen sulfide (H2S) are present, acid gases form and cause corrosion in pipelines, which can damage downstream equipment. To ensure safe and reliable operations, organizations must remove free H2O from natural gas. Many governments and/or agencies regulating shared pipelines maintain restrictions on the H2O content of sales gas or fungible product. While many options
