Many chemical and physical processes are available for processing or refining natural gas. However, there are many variables in the choice of refining sequence that dictate the choice of process or processes to be employed. In this chapter, several factors must be considered: (1) the types and concentrations of contaminants in the gas, (2) the degree of contaminant removal desired, (3) the selectivity of acid gas removal required, (4) the temperature, pressure, volume, and composition of the gas to be processed, (5) the carbon dioxide–hydrogen sulfide ratio in the gas, and (6) the desirability of sulfur recovery due to process economics or environmental issues. The focus of this chapter is a selection of the processes that are an integral part within the concept of production of a product (methane) suitable for sale to the consumer.
