Correlation of vapor-liquid equilibrium ratio of hydrogen
- Purdue Univ., West Lafayette, IN (United States). School of Chemical Engineering
In this work the correlation of vapor-liquid equilibrium ratio of hydrogen in the Chao-Seader correlation is updated with the use of new experimental data that have appeared in the intervening years. The correlation is extended in the direction of high temperature where much new data have been reported over a wide pressure range. The hydrogen correlation in the Chao-Seader correlation was based on experimental data in the temperature range of approximately 200--530 K that was the full extent of available data at the time. Grayson and Streed (1963) extended the hydrogen correlation to higher temperature using proprietary data on oil fractions. Since then a great deal of experimental investigation has been performed to determine the solubility of hydrogen at temperatures up to 730 K and pressure up to 25 MPa. Sebastian and coworkers (1981) developed a correlation for the solubility of hydrogen based on the expanded database. In this work the authors develop a new equation for the standard state liquid fugacity of hydrogen based on the expanded current database. The new equation will be useful to replace the equation for v of hydrogen in the Chao-Seader correlation that is found in process design software packages.
