Hi, i am facing problem with using "Triolein" in Aspen Plus as the following message appeared when i try to run the flowsheet. I have tried use different property packages such as UNIQUAC, NRTL, but same error occurs. I would like to know if i want to use triolein as my vegetable oil to react with methanol, is it any special step i need to do before i can run the simulation? Thank you.

*** SEVERE ERROR IN PHYSICAL PROPERTY SYSTEM
EQUATION OF STATE MODEL ESRKA HAS MISSING PARAMETERS:
OMGRKA AND ITS DEFAULT OMEGA (DATA SET 1) MISSING FOR COMPONENT TRIOL-01

****PROPERTY PARAMETER ERROR
ERRORS ENCOUNTERED IN CALCULATION OF VAPOR MIXTURE PROPS USING
OPTION SET RK-ASPEN FOR PHIMX

! Calculations stopped because of missing property parameters

Hei, try to use the biodiesel production aspen plus simulation made by Michael Haas Michael.haas@ars.usda.gov. You can ask for help.

I found the same missing parameters when i started my own simulation for my graduation work and after making it within his process simulation, it worked very well, but with my added improvements in reaction kinetics to yield methyl esters from olein.
