In order to be transported and used under secure conditions, the natural gas must meet a set of quality requirements that also include a maximum value of the dew point for water from the commercial delivery/ pickup point. This assumes the treatment of natural gas in order to reduce the water vapour content, using dedicated equipment, named gas drying or dehydration stations. The materials or substances used for gas dehydration, on an industrial scale and for many years, in the natural gas production areas, are part both of the adsorbent substances category as well as of the absorbent substances category. The paper presents the theoretical and practical aspects regarding the determination of gas humidity and a synthesis of the real casuistry related to exploration of gas dehydration stations by underlining the problems concerning the proper performance of these stations.
