Moisture In Natural Gas

All natural gas contains water (moisture) which is measured in natural gas pipelines at production and gathering sites, custody transfer points, compression stations, storage facilities and in the distribution markets. Several methods are used for dehydration such as pressurizing, chilling, and absorption processes that use liquid and solid desiccants. Commonly, dehydration is achieved in the field with triethylene glycol (TEG) contactors. Glycol carryover to the analyzer is more likely at closer proximities to the outlet.
