How GasProps2008.DLL can help you solve problems
- Sonic Prover Calculations --- the calculated speed of sound times the cross-sectional area at the minimum diameter of a sonic prover is the volume flow rate
- Ultrasonic Meter Speed of Sound Validation --- check the calculations of the speed of sound used by the ultrasonic meter to calculate flow rate
- Flow Computer Properties Validation --- check the gas properties calculations of an electronic flow meter
- Joule-Thomson Temperature Drop Calculations --- – calculate temperature drops across valves and pressure regulators to assess the potential for liquid water and hydrates
- Compressor Troubleshooting Calculations --- compare actual operating conditions versus design conditions to determine deterioration in efficiency, increased power requirements, increased internal recycle, and if discharge temperature exceeds lubricant maximum
- Heat Exchanger Design Calculations --- calculate natural gas heat exchanger duties and temperature profiles (GasProps2008 also can be used for air properties, and so for air coolers, and also for combustion gas, and so for heaters using combustion gas)
- Heat Exchanger Operation and Troubleshooting Calculations --- monitor heat exchanger efficiency, determine changes in heat transfer coefficient and fouling factor, detect leaks

GasProps2008.DLL replaces the product GasProps.DLL, which originally was released in 2003. GasProps2008.DLL is computationally more efficient that the original GasProps.DLL and provides more accurate Joule-Thomson coefficient calculations. Users accustomed to spreadsheet calculations using GasProps.DLL can easily convert an existing spreadsheet to GasProps2008.DLL simply by replacing the old macro with a new macro which is provided.
Note: GasProps2008.DLL was developed explicitly for use with Excel XP and has been used successfully with Excel 2007. GasProps2008 can be used with PCs using Windows versions Vista, XP, or 2000
Why GasProps2008 was developed
The suggestion to provide gas properties calculations in a spreadsheet format was made in 2002 by Jim Witte of El Paso Corporation to Ali Quraishi of the American Gas Association around the time that AGA Report No. 10 was in final draft. Starting with the source code developed by Warren Peterson of Transcanada Pipelines, Ken Starling, SAI founder, developed the GasProps software. Because of Jim Witte’s desire to have the Joule-Thomson coefficient included, a JT algorithm was developed for GasProps.

Licensing options for GasProps2008:
1. GASPROPS2008/SL software licensing and security utilizes Sentinel HASP SL, a product of SafeNet, Inc. which provides a SL (softlock) license installed on each individual licensed computer.2. GASPROPS2008/HL software licensing and security utilizes Sentinel HASP HL, a product of SafeNet, Inc., which provides a HL (hardlock) license installed on a USB hardware key. Consequently, the GASPROPS2008 software installed on any computer will run successfully when the HL USB key is present in one of the computer’s USB ports. Thus, the GASPROPS2008 HL license is portable; the HL USB key can be passed from one computer to another as a matter of convenience and flexibility.
3. GASPROPS2008/Server/IN software licensing and security utilizes Sentinel HASP SL, a product of SafeNet, Inc., which provides a SL (softlock) license with a licensed number of concurrent users (licensed seats) installed on a single licensed company server. Consequently, the GASPROPS2008 software installed on any company networked computer will run successfully when a licensed seat is available on the licensed company server. Thus, a great amount of flexibility is provided, because the GASPROPS2008 software can be installed on many more company networked computers than the licensed number of concurrent users. An additional feature of GASPROPS2008/Server/IN software licensing is the fact that license seats can be detached from the licensed server and installed on individual company computers which may be unable to connect to the licensed server. Clearly GASPROPS2008/Server/IN software licensing offers a licensing company a lot of flexibility.
4. GASPROPS2008/Server/UN is identical to GASPROPS2008/Server/IN except that it is intended for 101 to an unlimited number of license seats. The number of license seats may, however, be limited by a company’s server capacity.
