Open source for chemical components properties?

    Hi,

    About 5 months ago, I developed an excel unit converter addin. it was very useful and easy to use. (check my post here about it, link below)
    https://engage.aiche.org/communities/community-home/digestviewer/viewthread?MessageKey=bfbbf49b-a323-490f-a2fc-306ac9b60dd8&CommunityKey=de21ae11-bfdc-41b4-851d-84c7293f0d99&tab=digestviewer#bmbfbbf49b-a323-490f-a2fc-306ac9b60dd8

    I'd like to develop such a tool for chemical components properties. So I am looking for an open-source for these data.

    for example: once i select CH4 it gives me moleculer weight, critical pressure, .... etc.

    Hi Hassan,

    You can find many sources of data that will qualify as "open source."  However, the key issue is the quality of the data.  "Quality" means whether the various sources have evaluated, and the best one chosen for each property.  If data are not available, have the best estimation methods been used to predict the data?  Finally, does the database provide a reliable uncertainty estimate?  For over 40 years, AIChE has organized the DIPPR Project to meet the goal of providing the "best data" to the process industry, and the DIPPR pure-component database (Project 801) is considered to be the Gold Standard database.

    You can read more about DIPPR Project 801 at https://www.aiche.org/dippr/projects/801.

    I generally use ChemCad or Aspen program for this information. This can accomplished by using each program’s respective Excel Add-In.
