Abstract

Background: Critical monitoring of moisture content in annulus gas is required due to its detrimental effect on the pressure tube, leading to surface corrosion and finally the rupture of the pressure tube.

Methods and Results: The present work describes a simple and reliable thermo-analytical method for the quantitative determination of moisture in CO2 gas cylinders, using anhydrous barium chloride as the novel adsorbent material and simultaneous. Thermogravimetry - Differential Thermal Analysis - Evolved Gas Analysis (Fourier Transformed InfraRed Spectroscopy) [TG-DTA-EGA(FTIR)] as determination techniques.

Conclusion: Differential Scanning Calorimetry (DSC) coupled with Microscopy has been used to see the surface morphological variations during the heat treatment. The results of these studies are being discussed here.
