GERG-2004等方程用于CH4-H2混合物比容计算
Calculation of specific volumes of CH4-H2 mixtures via GERG-2004 and other equations
摘要
Abstract
When utilizing hydrogen-containing gases, such as coal-based synthetic natural gas and coke oven gas, it is important to get their accurate thermophysical property data. The specific volumes of CH4-H2 mixtures with different mixing ratios at different temperatures and pressures were calculated by the equations of GERG-2004, PR and RK. Arid the results were compared with literature experimental data. It was showed that at 130K, 140K and 159.2K, and high pressure, the calculated results from GERG-2004 equation were better consistent with the literature data than that from PR equation and RK equations. Meanwhile, all the three equations could also be applied to the specific volume calculation of CrL-H; mixture when the temperature was above 273.1SK and pressure was in 3.5MPa-7MPa. For the condition of 140K and 3MPa-9MPa, the calculated results from GERG-2004 equation were compared with those from PR equation and RK equations, and the credibility of the results still needed to be verified by the experimental data.关键词
