Simulate the ZNO desulfurization reaction.

Thread Content

During the simulated reaction process, the parameters for ZNO and ZNS were incomplete. . I chose the PR equation. . Since there is a methanation reaction later, what should be done now? * WARNING: The component “ZNO” has zero flow rate in the outlet stream. The fractional conversion has been adjusted by a factor of “0.4228994”. The EOS model ESPR lacks certain parameters: TCPR and its default value TC (Dataset 1) are missing for component ZNS; PCPR and its default value PC (Dataset 1) are missing for component ZNS; OMGPR and its default value Omega (Dataset 1) are missing for component ZNS. ** There is an error in the physical property system – the liquid phase cannot be determined using the ESPR EOS model. Temperature: 643.2 K; specified pressure: 0.1000E+06 N/SQM; calculated pressure: -0.3064E+37 N/SQM. The ESPR EOS model failed due to unrealistic conditions at a temperature of 643 K and a pressure of 0.100E+06 PA. Component mole fractions: H2: 0.2993E-01; O2: 0.1470E-02; N2: 0.1097E-01; CH4: 0.6719E-01; C2: 0.8430E-02; CO: 0.1292E-01; CO2: 0.6448E-02; H2S: 0.1722E-03; C6H6: 0.9887E-03; C10H8: 0.1612E-02; H2O: 0.6927E-03; ZNS: 0.8592. **** Error in property parameters; errors were encountered during the calculation of vapor-liquid equilibrium constants using the PENG-ROB option for KVL calculations! Calculations were stopped due to missing property parameters
