Abstract:

In chemical process industries, a network of piping system holds gases in huge quantities and contains a low, moderate, and high concentrations of water moisture. The presence of moisture in these gas streams is highly undesired, particularly in the case of natural gas lines. At low temperatures water condenses in the pipelines and may be a reason for a number of technical problems. An adequate method for the gas dehydration is decided on the basis of moisture concentrations. The detection and quantification of the actual values of water vapour concentrations in gas streams is very important. Measurement of the low concentration of water vapors is very difficult. This work presents that one may determine an extremely low water vapour concentrations in a continuous flow system by placing a fixed mass of zeolite 3A molecular sieves. For example, an air gas mixture having a known dilute concentration of water vapours (5470 ppm) when passed over a zeolite 3A adsorbed 7.6 mmolkg-1of water vapours.
