PROII/9.0 PATCH1出来了? ********************************************************** **** PRO/IITM v9.0.1 (Patch to v9.0) ***** **** SIMSCI-ESSCOR Date: May 2011 ***** ********************************************************** The following README file contains installation instructions and a list of changes (problems fixed or features added) that will be implemented on PRO/II version 9.0 once this Patch is applied. This patch can be installed over v9.0. ******************************** * How to install this Patch * ******************************** To install Proii90Patch1.zip: 1. Make sure you are not running PRO/II simulation. This may be verified through Task Manager in Windows 2003, Windows XP, VISTA?and Windows 7 operating systems. 2. To receive this Service Pack, copy and unzip the PROII90Patch1.zip file on your system. On more recent OS's, the zip file may appear as a folder in which case you can proceed directly to step 4. 3. When prompted, enter the path to the directory where you want the files to be unpacked (for example, C:\TEMP\PROII90). Important: when you unzip the files, make sure to select the "use folder names" option (or equivalent) so that the required subdirectory structure is created at the location where the file is unzipped. 4. After the file has been unzipped, go to the directory where the files were extracted (for example, C:\TEMP\Proii90) then go into the subdirectory "PROII90Patch1". Double click on update.exe to begin installing the PRO/II patch. This setup will install the PRO/II patch. If you did not unzip the folder first, it will take a few moments for the computer to respond to your double click as the unzipping has to occur first. Do not double click again or you will launch a second instance of the install. 5. Select the "Next" Button on the Welcome Screen and the install starts installing the updated modules. 6. Select the "Finish" button. The Patch will be copied onto your hard drive and will automatically begin installing. 7. When the installation of the PRO/II patch has been completed, the following files will be updated on your system: \Proii90\Bin\CapeOpenExec.dll \Proii90\Bin\LMAccess.dll \Proii90\Bin\MFLib.dll \Proii90\Bin\MTOCOCustom.tlb \Proii90\Bin\MTCppGUI.dll \Proii90\Bin\MTLib.dll \Proii90\Bin\MTPointerLink.dll \Proii90\Bin\MTWrapper.dll \Proii90\Bin\P2Interface.dll \Proii90\Bin\P2oledbs.exe \Proii90\Bin\PESCalcMain.dll \Proii90\Bin\PESGuiMain.dll \Proii90\Bin\RATEFRAC.dll \Proii90\Bin\proii.exe \Proii90\Bin\ProII_KGTower.exe \Proii90\Bin\RateFrac.dll \Proii90\Bin\RGLib.dll \Proii90\Resource\solidsremoval.bin \Proii90\Resource\thermo.bin \Proii90\System\p2.kgs \Proii90\System\p2.xsf \Proii90\System\p2.xvf \Proii90\System\PROII.sp1 \Proii90\System\PROII.sx1 \Proii90\System\PROII.sx2 \Proii90\System\PROIIDB \Proii90\System\uomdata_proii.txt \Proii90\System\UnitXML\SOLRemoval.xml \TDM\*.* /s (Some SIM4ME thermo files have been updated) **************************************************** * Defects corrected in PRO/II v9.0.1 (patch 1) * **************************************************** Number Feature Description HIPE#20314 Amsim Converting a file with an Amsim unit operation from 8.3 to 9.0, the new .prz works fine but the _v83.prz does not contain the required .apj file. The file won't run in v8.3 because it lacks the Amsim model. LFPE#28095 Assay With Cubic Spline and IF97, recalculating the assay breakdown may result in a Bad Pointer Starting Address error. LFPE# 28165 Assay There is a small error that can be introduced in the calculated TBP result when there are multiple components that cover exactly or nearly the same range. For exmaple, if there are two blends with the following: CUTPOINTS TBPCUTS=100,800,28/1200,8/1600,4, DEFAULT CUTPOINTS TBPCUTS=100,800,28/1200,8/1600,4, BLEND=A you may end up with a TBP value (any percent), that is not exactly on the line plotted by lv% vs T of any of the resulting streams. Most of the points will be correct. If the problem shows up, it may have one point that is off by 2 degrees or so. On one occasion we saw a result that was off by more. HIPE#20352 Cape Open Cape Open COCO_COUS mixer convert from PROII83 to PROII90 gives a crash when there are more than 6 feeds. HIPE#20372 Cape Open A CAPE-OPEN Property package name having embedded space is not supported through keywords. HIPE#20382 Cape Open Properties retrieved via Cape Open thermo have non-sensical values. These were OK in v8.3. Properties affected include density, surface tension, thermal conductivity and viscosity. HIPE#20385 Cape Open File convert via .com (Say, from Excel) of a file PRZ containing Cape Open COCO units fail because the relevant .dat file is not containerized in the .prz. LFPE#27981 Case Study Choose to run Base Case only in Case Study problem may result in an error message that the PARAMETER 'PARAM1', changed during calculations in cycle 1. Since cycle 1 is not run, there should have been no error message. LFPE#28076 Column The <Liquid> tag information on the xml file for data transfer to FRI's DRP program or Koch-Glitsch KGTower reports the Liquid To rather than the Liquid From. HIPE#20503 Column The Ratefrac Electrolyte column crash may crash when hydraulics data are present using the built-in SCRU70 thermo package. Other built in packages, like SOUR and MEA are fine. HIPE#20319 Component User supplied VP data using correlation 20 will be incorrect if the parameters are supplied using deg R. deg K is OK. LFPE#28143 Component The critical Pressure for mercury is incorrect Databank in the PROCESS databank. LFPE#28096 Compressor The the user-supplied Polytropic Efficiency for a compressor does not persist after OKing back to the PFD level. LFPE#28136 Compressor Compressors with primarily vapor, but some liquid feed, and VLLE thermo, results in a bad outlet condition calculation, even though there is only one liquid phase. VLE thermo works correctly. LFPE#28152 Flash In one case, the dew point calculation for an all water stream using IF97 results in incorrect enthalpy near the critical. HIPE#20285 PFD The stream icon on the build palette turns red (unsatisfied) after a Save As operation. Click around the PFD restores it to the correct black color. LFCR#4298 Reaction 揇efine?is being ignored in column reaction data Data for the Pre-Exponential Factor and resets it to a value of 1.0 LFPE#28115 Security Starting PRO/II 9.0 with TokenNet security may result in a security error message about the license expiration date, even though the license is good. HIPE#20370 Solids The Solid removal unit does not material balance when the feed is a solids-only stream. HIPE#20378 Solids The energy balance is not attained for solid removal unit operation. HIPE#20473 Solids The Plant Material Balance Table could be in error if decant water is present. LFPE#28105 Solids Solids Removal adiabatic option does not result in the correct temperature in at least one case. LFPE#27921 Spreadsheet After running a file, click on Tools/Spreadsheet Tools /Stream Properties. At the conclusion of laying out the spreadsheet it may crash with a p2oledbs.exe application error. 'The instruction at "0x7c9116f4" reference memory at "0x001a4era". The memory could not be "written".' LFPE#28112 Stream The Find Stream and Find Unit are not alpha sorted in v9.0. LFPE#28106 Stream When a Stream Property Table is present and rate Property in liters/day is requested, the file is exported Table to keywords as LIT/DAY for the Stream Report Writer. LIT/DAY is not accepted in import. The workaround is to change the keyword to L/D. HIPE#18602 Thermo The Unifac group breakdown is incorrect for the following components: CITRONIC, DC9PHEN, DEAA, HYOXCAPR, MALIC, MALONIC, MERPRO, METOXYAC, HNEOC5, PYRUVIC. HIPE#20447 Thermo The parachor surface tension calculation is incorrect for single component flowsheets LFCR#4208 Thermo The Unifac group breakdown is incorrect for the following components: 1M2PRBZ, 1M3PRBZ, 1M4PRBZ, MMSTYR, OMSTRY, 4HSTYREN, IPCH, 2MNON, 4MNON, 5MNON." LFPE#27975 Thermo Using GPSA water saturation, if the stream is nearly pure in a vapor-liquid mix, adding more liquid water decreases the vapor water flowrate. This is because there is a cutoff concentration for pure-component handling (in this one scenario) that is not close enough to 1.0. HIPE#20403 Update Initial Updating controller the current variable values Estimates to a stream estimate updates the field to the moles/hr value even when the UOM for that field is mass/hr. HIPE#20488 User Added A User Added Subroutines linked with Intel?VF 8 may not work subroutines because of extraneous routines listed in the .sln file. 查看更多 23个回答 . 4人已关注
