Title: Thermodynamic behavior of hydrogen/natural gas mixtures

Abstract

The process gas of ethylene plants and methyl tertiary butyl ether plants is normally a hydrogen/methane mixture. The molecular weight of the gas in such processes ranges from 3.5 to 14. Thermodynamic behavior of hydrogen/methane mixture has been and is being researched extensively. The gas dynamic design of turboexpanders which are extensively utilized in such plants depends on the equations of state of the process gas. Optimum performance of the turboexpanders and associated equipment demands accurate thermodynamic properties for a wide range of process gas conditions. The existing equations of state, i.e. Benedict-Webb-Rubin (BWR), Soave-Redlich, Kwange and Peng-Robinson have some practical limitations. The equations of state developed by the University of Illinois also have only a limited range of applications. By using the various equations of state, especially in the vapor-liquid equilibrium region, this paper shows that predictions by the various models are not the same and that they also differ from actual field results. The field data collected for hydrogen/methane mixtures are in the range of 100 F to {minus}200 F containing some polar components i.e. H{sub 2}S and CO{sub 2}. In this paper, the authors compare performance of several equations of state with the field performance of manymore » expander units.« less
