eRCM Gas Modeling™  Software 

Version 1.2.2
(Update v1.2.2)

Software is Free

For full NIST software and their extensive line of databases for fluids, visit: http://www.nist.gov . 

Notes on RCM_Gas_Model Installation: Download the ACI_eRCM_NIST.msi file to your hard drive. After it has completely downloaded, run the program and follow onscreen prompts to finish the installation.

Notes on Updating your Software: Exit the software if it's currently running. Download the eRCM_Gas_Model_Update.EXE file to your hard drive. After it has completely downloaded, run the program and tell it to self-extract its files to your ACI NIST installation folder -- typically this will be "C:\Program Files\ACI_eRCM_NIST" and elect to overwrite the existing files.

For technical issues about the performance software, or for assistance in it use, please contact Dwayne Hickman at ACI Services, Inc.

Only gas properties useful for gas compression are covered in the ACI Gas Modeling program. If you need more extensive data about gases and mixtures, then please follow the link to NIST and review their array of software for thermodynamic properties of fluids.
