Natural gas stream from production wells is saturated with water vapor, which may condense in pipelines, resulting in erosion and corrosion. When accumulated in the pipelines, it might form liquid plug, reducing the pipeline flow capacity. To avoid these potential problems, the gas stream needs to be dried to lower its water dew point. Mercury is present in many natural gas streams, and the levels can vary among different fields. Low levels of mercury are health hazards and will damage aluminum heat exchangers and equipment that are susceptible to corrosion attack by mercury. While this chapter addresses natural gas dehydration methods as well as the design and operational aspects of the relevant unit, the different methods and configurations of mercury removal unit are also discussed at the end.
