Problem Statement: How to make Oligomer volatile when using equations of state method? | Solution: Equations of State method is using fugacity coefficient for flash calculation so the oligomer is volatile in default. Segment property is used for the calculation of oligomer. But the volatility may not be a correct because this model is purposely designed for high molecular polymer. User need to adjust follo... |
Problem Statement: How to make Oligomer volatile when using activity coefficient method? | Solution: Activity Coefficient method is using PLXANT parameter for flash calculation. But the default PLXANT value for polymer (or oligomer) is set to low value to disable the vaporization. And most of polymer activity coefficient method (except PNRTL-IG) is using RK EOS for vapor fugacity calculation. User need to ad... |
Problem Statement: Why am I not getting a warning message when my PSV line velocity exceeds the defined limit (set as percentage of sonic velocity)? | Solution: The velocity constraints are applied for single-phase (not homogeneous) line sizing. This line sizing method is only available for vapor and steam orifice sizing; direct integration orifice sizing will always use homogeneous line sizing regardless of the fluid phase. In V10 homogeneous line sizing, we don't c... |
Problem Statement: Can I use an input solution generated in a previous case of the same PIMS run? For example, I run cases 1 and 2, but I want an input solution created from case 1 to be the input for case 2. | Solution: PIMS has Table CASE keywords that can be used to do this. Keyword SAVESOL tells PIMS to save an input solution file with the number designated in column B. For example, this entry tells PIMS to create input solution file 1 at the end of solving case 1.
