Thread Content

Dear colleagues: When using Aspen Plus V14 to simulate a 1 mol/L ammonium bicarbonate solution at 20°C, the following error message appears: Q. Could someone please help me determine what the problem is? “VAPOR PRESSURE MODEL PL0XANT HAS MISSING PARAMETERS: PLXANT/1ST ELEMENT (DATA SET 1) IS MISSING FOR COMPONENT AMMON-01.” “****PROPERTY PARAMETER ERROR: ERRORS WERE ENCOUNTERED IN THE CALCULATION OF VAPOR-LIQUID K-VALUES USING THE OPTION SET ENRTL-RK FOR KVL.” Here, AMMON-01 refers to the component ammonium bicarbonate provided by the software; its CAS number is 1066-33-7. The thermodynamic method used is ENRTL-RK. Please provide solutions to this problem. Thank you! :handshake
