The influence of the presence of gasses in mineral oil on the ability of molecular sieves for water sorption

Abstract

Previous studies has shown, that for the same relative humidity, the ability of molecular sieves to adsorb water in the air is higher than in mineral oil. One of the reasons for this difference may be the presence of dissolved gasses in the mineral oil. The effect of the presence of gasses in mineral oil on the ability of molecular sieves to adsorb water was experimentally investigated. Samples of non-degassed and degassed mineral oil with a similar initial water content were dried by means of activated 3A and 13X molecular sieves. The obtained results allowed to show that in the studied range of gas content in oil they do not affect the ability of molecular sieves for water sorption.
