Adsorbents for the natural gas drying at CNG stations

Original language description

Humidity present in the natural gas causes problems by its compression at CNG filling stations, therefore the natural gas has to be dried before compression. For this reason is mostly used the water adsorption from the gas at suitable adsorbent. Device for drying compressed natural gas at high pressure is therefore an important part of the CNG filling station and affects the quality of produced CNG. For the correct operation of the drying equipment is a decisive the selection of the suitable material for the adsorption of water vapor from the gas. As adsorbents for the removal of water from the gas are primarily used molecular sieves 4A, 5A, and 13X. Molecular sieve 4A has a high sorption capacity for water vapor, which is, however, significantly reduced by co-adsorption of methane at high pressures. Other molecular sieves have not so high sorption capacity for water, but the influence of co-adsorption of methane at high pressures is by these adsorbents not so significant. The article is focused at selection of commercially available adsorbents having high capacity for water steam and high efficiency by its removal from the gas. The results of laboratory tests of methane drying have been used to the selection of best adsorbent for natural gas drying at CNG stations.
