Available in PDF, EPUB and Kindle. Book excerpt: Extensive comparisons of calculated viscosities with experimental data for pure gases were undertaken over a temperature range from 200 to 1000 K and a pressure range from 1 to 980 atm. The overall average absolute deviations for the viscosity of gas mixtures such as carbon dioxide-methane, argon-neon, carbon dioxide-krypton and hydrogen-nitrogen were less than one percent. The procedure for the prediction of the viscosities for mixtures is simple and straightforward. Only the critical parameters, the accentric factor, and the viscosity at low pressure for the gases are required.

Available in PDF, EPUB and Kindle. Book excerpt: Relationships which can be used to estimate the density, heat capacity, viscosity, thermal conductivity, and diffusivity of gases and multicomponent gas mixtures are presented and reviewed. These relationships were incorporated into a computer program for calculation and compilation of the properties for the desired components and mixtures at temperatures and pressures specified by the user. The calculations are made either by extrapolation of experimental data given at conditions other than those desired or by using the critical and molecular properties of the gases. The computer program was used to solve a sample problem dealing with the physical properties of carbon dioxide, oxygen, and nitrogen mixtures.
Download or read book Determination of Viscosity of Exhaust gas Mixtures at Elevated Temperatures written by J. C. Westmoreland and published by . This book was released on 1954 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: The viscosities of five samples of dry-exhaust-gas mixtures at approximately atmospheric pressure and at temperatures from 0 degrees to 1,100 degrees C are presented. A method of analysis and correlation proposed by Sutherland has been applied to the data and equations were derived therefrom for representing the results. It is believed that these equations may be used for computing viscosities of all mixtures haing compositions within the range of the five studied at any temperature up to about 1300 degrees C. The effect of moisture upon the viscosity of exhaust gas was computed by a relation developed from experimental values for moist air. In a check determination of moist exhaust gas, the experimental viscosity differed less than 1 percent from the calculated value.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Modeling the performance of high-pressure, high-temperature (HPHT) natural gas reservoirs requires the understanding of gas behavior at such conditions. In particular, gas viscosity is an important fluid property that directly affects fluid flow through porous media and along production flowlines. Accurate measurements of gas viscosity at HPHT conditions are both extremely difficult and expensive. Unfortunately, the correlations available today do not have a sufficiently broad range of applicability in terms of pressure and temperature since no measured gas viscosities at HPHT are currently available. Thus the correlation accuracy may be doubtful for the prediction of gas viscosity at HPHT conditions. An oscillating-piston viscometer was used to measure the viscosity of mixtures of nitrogen and methane, and mixtures of CO2 and methane at a pressure range of 5,000 to 25,000 psi, and a temperature range of 100 to 360 degrees F. The viscosity of mixtures of nitrogen and methane, and mixtures of CO2 and methane measured to take into account of the fact that the concentration of non-hydrocarbons increase significantly in HPHT reservoir. The recorded measured data were then used to evaluate the reliability of the most commonly used correlations in the petroleum industry. Measured gas viscosity data at HPHT conditions suggest that the most common gas viscosity correlations return up to 9% relative error in gas recovery factor, which translates into a significant error in estimating the ultimate recovery for large HPHT natural gas reservoirs. Thus, the current gas viscosity correlations need to be adjusted to estimate gas viscosity at HPHT conditions. New gas viscosity correlations constructed for HPHT conditions developed based upon our experiment data provide more confidence on gas viscosity. A rolling ball viscometer was also used to assess its capability to measure gas viscosity. Using gas instead of liquid to calibrate a rolling ball viscometer over the entire pressure and temperature range of interest appears to be satisfactory. Optimizing tube inclination angle and ball/tube diameter ratio prevents turbulent flow effects around the ball, thus enhancing the accuracy of the measurement. The proposed calibration method was then verified with pure CO2 at a pressure range of 4,000 to 8,000 psi, and a temperature range of 98 to 240° F. Consequently, rolling ball viscometer was introduced as a good candidate to measure the gas viscosity; however it has not been tested at HPHT conditions yet.
