    Ammonium Nitrate data bank

    Hi all,
    Right now i'm trying to simulate nitrous oxide plant from decomposition of ammonium nitrate.
    Right from the start, i already meet a problem. It seems that Aspen Plus do not have complete data bank
    for ammonium nitrate.

    I want to ask about what is the proper fluid package/ thermodynamic method for ammonium nitrate decomposition
    system. I tried to use ELECNRTL, since i think ammonium nitrate is an electrolyte, and i get this warning/error

    WARNING IN PHYSICAL PROPERTY SYSTEM
    PARAMETER PLXANT (DATA SET 1) FOR COMPONENT NH4NO-01:
    UNREASONABLE VAPOR PRESSURE CALCULATED AT TEMPERATURE UPPER BOUND.
    VALUE SHOULD BE LESS THAN MAXIMUM ALLOWABLE VALUE
    = 0.10000E+36 N/SQM. PLEASE CHECK YOUR INPUT FOR THE
    ANTOINE PARAMETERS.

    * WARNING WHILE CHECKING INPUT SPECIFICATIONS
    BLOCK NAME: B1 MODEL NAME: RCSTR
    PHYSICAL PROPERTY PARAMETER DHFORM OR DHAQFM IS MISSING
    FOR THE FOLLOWING COMPONENTS:
    NH4NO-01
    ABSENCE OF THIS PARAMETER WILL RESULT IN INCORRECT ENTHALPY RESULTS.


    WATSON HEAT OF VAPORIZATION MODEL HAS MISSING PARAMETERS:
    DHVLWT/1ST ELEMENT (DATA SET 1) MISSING FOR COMPONENT NH4NO-01

    DHVLWT/2ND ELEMENT (DATA SET 1) MISSING FOR COMPONENT NH4NO-01

    ****PROPERTY PARAMETER ERROR
    ERRORS ENCOUNTERED IN CALCULATION OF IDEAL GAS PROPS FOR
    HIG
    PLEASE FIX THE ERRORS, RE-INITIALIZE, AND RUN AGAIN.

    Has anyone try simulating the same system? I'll be glad if anyone can help me solve this problem.

    Best regards,

    Re: Ammonium Nitrate data bank

    The solution is we can input the missing parameter ourselves, in the properties>parameter>pure component

    The definition of each parameter also can be seen in that page when we choose the parameter
