Abstract
A process for treating a gas containing methane, at least one higher hydrocarbon and water to eliminate the water and/or extract the higher hydrocarbon(s) comprises dividing the gas to be treated into at least two fractions each of which undergo at least one cooling step, and bringing an aqueous phase fraction obtained after cooling into contact with the gas to be treated. The treatment process uses units with reduced floor space and weight.
