Gas Compressibility

The fixed volum e expansion method for gas compressibility measurements previously employed under conditions of high temperature and high pressure has now been developed for low temperature and low pressure measurements. A sensitive diaphragm null-pressure detector, operating as a capacitor, has been incorporated into the gas pipettes, and eliminates troublesome dead space corrections. The advantages and limitations of the method are discussed. Measurements of the second virial coefficient of carbon dioxide in the temperature range −60 °C. to + 30 °C, and in the pressure range 0.5 to 2.5 atmospheres, are reported.

Abstract Presents data on corrosion of heat resistant alloys by high pressure carbon dioxide. Describes oxidation behavior of 26 alloys in 1000 to 2000 psi carbon dioxide in temperature range of 1100 to 1740 F. Oxidation rates of heat resistant alloys in 2000-psi carbon dioxide at 1300 and 1500 F were very low. In all cases, scales were protective. Oxidation followed a parabolic or slower rate law. At 1740 F, most alloys tested exhibited excessive scaling in 1000-psi carbon dioxide. 3.4.6
