Anene:

The typical specifications on water content of pipelined natural gas ranges from 1 to 5 pounds per 10⁶ standard cubic feet of gas ... which is equivalent to a range of 20 to 100 ppm by volume. The two primary reasons for removing water from the gas are: (a) to reduce corrosion of the pipeline and (b) to avoid the formation of solid hydrates in the pipeline.

If the raw natural gas is treated to recover natural gas liquids (NGL) such as propane, butane and pentane or higher hydrocarbons, that provides another reason ... to prevent contaminating those products with water.

If the raw natural gas is to be liquified and sold as LNG, the water must be removed because it would freeze into solid ice at the temperatures required for liquifying methane.

Note: In any of your future messages posted here, note that the correct spelling is "you" rather than "u", "please" rather than "plz", "your" rather than "ur" and "thanks" rather than "thx". If you really want to be a professional engineer some day, you must learn to communicate correctly.
