Proii input file

I'm studying* When using Proii, I found that the .inp file output by the model I built is a little different from the one in the book, but I don’t know how to adjust it. I would like an expert to take a look. my inp file: $ Generated by PRO/II Keyword Generation System $ Generated on: Wed Apr 15 16:38:40 2009 TITLE PROJECT=STRIPPER, USER=MXL, DATE=090413 DESC study 15 DESC PRINT STREAM=ALL, RATE=M,WT, FRACTION=M, PERCENT=WT TOLERANCE TEMPERATURE=-0.055556 DIMENSION METRIC, PRES=MPA, BANK=PROCESS,SIMSCI THERMODYNAMIC DATA METHOD SYSTEM=SOUR, TRANSPORT=PURE, SET=SOUR01 METHOD SYSTEM=NRTL, TRANSPORT=PURE, ENTHALPY(L)=SRKM, & ENTHALPY(V)=SRKM, DENSITY(V)=SRKM, SET=NRTL01, DEFAULT STREAM DATA PROPERTY STREAM=S01, TEMPERATURE=40, PRESSURE=0.45, PHASE=M, & RATE(WT)=50000, COMPOSITION(WT)=1,98.6595/2,0.3899/3,0.5333/ & 4,0.4173, NORMALIZE PROPERTY STREAM=S06, TEMPERATURE=40.5, PRESSURE=0.19613, PHASE=M, & RATE(WT)=8899.99, COMPOSITION(WT)=1,96.9641/4,3.0359 PROPERTY STREAM=S14A, TEMPERATURE=60, PRESSURE=0.78453, PHASE=M, & COMPOSITION(WT,KG/H)=1,40911/2,2/3,109/4,157.5 UNIT OPERATIONS MIXER UID=V102, NAME=V102 FEED S06,S01 PRODUCT M=S11 OPERATION PRESSURE=0.2942 PUMP UID=P103, NAME=PUMP FEED S11 PRODUCT M=S12 OPERATION PRESSURE=0.7 SPLITTER UID=SP1, NAME=SP1 FEED S12 PRODUCT M=S14, M=S13 OPERATION OPTION=FILL SPEC STREAM=S13, RATE(WT,KG/H),TOTAL,WET, DIVIDE, STREAM=S12, & RATE(WT,KG/H),TOTAL,WET, VALUE=0.15 HX UID=C-1, NAME=COOLER HOT FEED=S13, M=S13C UTILITY WATER, TIN=20, TEMPERATURE=25 CONFIGURE COUNTER OPER HTEMP=35 END inp file in the book: TITLE PROJECT=STRIPPER, USER=MXL, DATE=090413 DESC study 15 DESC PRINT STREAM=ALL, RATE=M,WT, FRACTION=M, PERCENT=WT TOLERANCE TEMPERATURE=-0.055556 DIMENSION METRIC, PRES=MPA, XDENSITY=SPGR, STDTEMP=0, & STDPRES=0.101325 SEQUENCE SIMSCI CALCULATION TRIALS=80, RVPBASIS=APIN, TVP=37.778, RECYCLE=ALL COMPONENT DATA LIBID 1,H2O/2,CO2/3,H2S/4,NH3, BANK=PROCESS,SIMSCI THERMODYNAMIC DATA METHOD SYSTEM=SOUR, TRANSPORT=PURE, SET=SOUR01 METHOD SYSTEM=NRTL, TRANSPORT=PURE, ENTHALPY(L)=SRKM, & ENTHALPY(V)=SRKM, DENSITY(V)=SRKM, SET=NRTL01, DEFAULT STREAM DATA PROPERTY STREAM=S01, TEMPERATURE=40, PRESSURE=0.45, PHASE=M, & RATE(WT)=50000, COMPOSITION(WT)=1,98.6595/2,0.3899/3,0.5333/ & 4,0.4173, NORMALIZE PROPERTY STREAM=S06, TEMPERATURE=40.5, PRESSURE=0.19613, PHASE=M, & RATE(WT)=8899.99, COMPOSITION(WT)=1,96.9641/4,3.0359 PROPERTY STREAM=S14A, TEMPERATURE=60, PRESSURE=0.78453, PHASE=M, & COMPOSITION(WT,KG/H)=1,40911/2,2/3,109/4,157.5 UNIT OPERATIONS MIXER UID=V102, NAME=V102 FEED S06,S01 PRODUCT M=S11 OPERATION PRESSURE=0.2942 PUMP UID=P103, NAME=PUMP FEED S11 PRODUCT L=S12 OPERATION PRESSURE=0.7 SPLITTER UID=SP1, NAME=SP1 FEED S12 PRODUCT M=S14, M=S13 OPERATION OPTION=FILL SPEC STREAM=S13, RATE(WT,KG/H),TOTAL,WET, DIVIDE, STREAM=S12, & RATE(WT,KG/H),TOTAL,WET, VALUE=0.15 HX UID=C-1, NAME=COOLER HOT FEED=S13, L=S13C UTILITY WATER, TIN=20, TEMPERATURE=25 CONFIGURE COUNTER OPER HTEMP=35 END I have marked the different places in blue. Mine is PRODUCT M=S12, but the data shows PRODUCT L=S12. I don’t know what the M and L here mean respectively? How can I build a model so that the .inp file of my model is consistent with the data? I imported both .inp files into Proii 7.1 and checked the settings of the last heat exchanger (HX UID=C-1, NAME=COOLER). They are exactly the same? Paste the above file into Notepad, change the suffix to .inp, and import it into Proii to view the model. Please give me some advice, thank you.

M should mean that the phase state of the material is a mixed phase (both gas and liquid), and L means the pure liquid phase. Take a closer look to see if it looks like this.

It's just a matter of logistics name and phase. Check, are your logistics names and examples for each share the same?

The conditions I entered were exactly the same as the example problem, but mine did not converge. But since it is an .inp file, it shouldn't have anything to do with whether it is converged, right? If the input conditions are the same, why are they different? In addition, I found that the bottom of the flash tank leaves the stream. If it is connected to the lower part of the tank, the .inp file will show "M=” ; If the bottom leaves the logistics and is connected to the side of the tank, the .inp file will be displayed as "L=" ; Obviously, it has nothing to do with phase. I hope the experts can correct me.
