摘要

本研究介绍了一种简单可靠的热分析方法，用于定量测定二氧化碳气瓶中的水分，该方法采用无水氯化钡作为新型吸附材料，并同时采用热重分析法、差热分析法、气体进化分析法（傅立叶变换红外光谱法）[TG-DTA-EGA(FTIR)]作为测定技术。差示扫描量热法（DSC）与显微镜相结合，用于观察热处理过程中的表面形态变化。本文将讨论这些研究的结果。

Moisture Determination in CO2 Gas Cylinders for Application in Annulus Gas Monitoring Systems of Pressurized Heavy Water Reactors (PHWRs)

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. 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. 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.
