Gasprop calculates the physical and thermodynamic properties of a natural gas mixture, given the compositional data. You can input the mole percentage composition of each component in the natural gas mixture, such as 85% methane, 10% ethane, etc. and Gasprop will calculate the apparent molecular weight and gravity (relative to air =1.00) of the natural gas mixture, along with other properties such as viscosity, specific heats, Cp and Cv, the ratio Cp/Cv, and the Compressibility factor Z at a specified temperature and pressure. The latter can be calculated using one of the various methods, such as Standing and Katz, AGA method, etc. The built-in database of gas component properties can also be updated by the user.
You may use this program in conjunction with our hydraulic simulation model GASMOD, to input a compositional model of the natural gas transported through the pipeline.
Gasprop runs on Windows 2000/XP and Windows Vista. Network versions available. Technical Support:
Free Technical Support is provided for registered users of this software for a period of one year from the initial purchase date. After that period, Technical Support can be provided only if an annual Software Maintenance and Technical Support (SMTP) plan has been purchased. Minor program updates and maintenance releases are posted at SYSTEK's Web site for licensed users to download free of charge. You may need to contact SYSTEK to obtain a password for downloading and installing an updates from the web site. Major upgrades are issued twice a year at special prices to current licensed users. Call or write for details of SMTP plan.
We welcome comments and suggestions from users. Please give us your thoughts on how GASPROP can be improved further. Our goal is to make this software the most user-friendly program available for engineers.
