Natural gas and associated condensate are often produced from the reservoirs saturated (in equilibrium) with water. In addition, the gas often contains CO2, H2S and heavy hydrocarbons which requires removal before exporting the natural gas to the consumers. Dehydration is a process used to remove water from the gas.

Dehydration of natural gas is very important as it is required to: • Prevent formation of hydrates in equipment and pipelines, • Prevent condensation of free water in processing and transportation facilities, • Prevent corrosion of equipment and pipelines, • Meet water content specification as per sales gas agreement.
