2. Thermodynamic Data Manager (TDM )

Pure Component Data Regression

Temperature-dependent thermo-physical property data can be fitted to any appropriate equation form Recognized properties (generally at saturation conditions) are : Vapor Pressure, Ideal Gas Enthalpy, Liquid and Solid Enthalpy, Latent Heat of Vaporization, Liquid and Solid Density, Liquid and Vapor Viscosity, Liquid and Vapor Thermal Conductivity, Surface Tension Equation Of State alpha terms can be fitted to pure component vapor pressure data

Mixture Data Regression

Binary and multi-component data can be regressed Recognized properties are: Equilibrium (VLE and LLE), Excess Enthalpy, Excess Volume and Activity Coefficients Multiple types of equilibrium data binary and higher order, VLE and LLE can be regressed to a single, consistent thermodynamic model (e.g. NRTL or SRK)

Basic Concepts Regression is activated from the main TDM screen

A regression run consists of a number of Cases Each Case contains a set of: Components Multiple Data Sets Multiple Calc Options Multiple Scenarios

Important NoticesCompatibility with Earlier Versions of PRO/IIPRO/II 4.1x, PRO/II 5.0x, PRO/II 5.1x, 5.5x, 5.6x, 6.0x, 7.x and 8.0x database files will automatically be converted into PRO/II 8.1 files as they are opened. The original file will be saved using an alternate file name.

Default changes in PRO/II v8.0:1. The databank search hierarchy has been changed from (Process, SimSci) to (SimSci, Process). In general the SimSci databank has more advanced data and should be used for all new simulations. If it is necessary to revert back to the Process databank, that can be done either on a simulation-by-simulation basis, or the default can be changed globally for all simulations on that PRO/II installation. To change the installation default, select the menu item Options/Simulation Defaults/Component Databank This change is saved in the \user\proii.ini file. The Assay curve fitting option default has been changed from Version 6 to Version 7. This affects how a stream TBP curveImportant Notices

that is constructed from volume percent of component cuts is interpolated and extrapolated. The Version 7 method corrects some problems that were present in the existing simulation. Most simulations will change very slightly or not at all because of this change. The most obvious change will occur for assay results that use the IP (usually 1 vol %) or EP (usually 98 vol %) as specifications. This was first offered in PRO/II v7.0 as the Alternate option, and made the default in v8.0. If it is necessary to revert back to the Version 6 method, that can either be done on a simulation by simulation basis, or the default can be changed globally for all simulations on that PRO/II installation. To change the installation default, select the menu item Options/Simulation Defaults/Assay Characterization This change is saved in the \user\proii.ini file. 3. 4.

PRO/II tube side pressure drop, clean, service transfer rates and roughness correlation have been updated to match HEXTRAN. There are two new heat exchanger defaults: Two Phase Heat Transfer Coefficient Method You may select the method to calculate the two-phase heat transfer coefficient. Following are the available options to be selected from drop-down list.

Chen - Modified Chen Vaporization method (NEW DEFAULT) HEX5 - Algorithm used in versions 7.1x and earlier

Tubeside Pressure Drop Method You may select the method to be used to calculate the tube side pressure drop. The options are:

"BBM" for the Beggs-Brill-Moody method (NEW DEFAULT) "HEX5" for the method used in versions 7.1x and earlier

PRO/II 8.0 Patch 1 addressed the concerns of some customers that users may run the risk of inadvertently running simulations defined by keywords using the new defaults on files that have been validated using the old defaults. The following changes have been made: 1. When a file is run from keywords, either via the menu item File/ Run Batch..., or from the DOS command line RUNP2 filename, the keyword file must explicitly state the component search hierarchy. Failure to do so will result in an input error message that details the required correction:7

PRO/II 8.1 Release Notes

*** ERROR *** Starting with version 8.0.1, PRO/II keyword files must specify the databank search hierarchy on the LIBID statement. To match the current GUI default specify the order as BANK = SIMSCI, PROCESS. To match simulations before version 8.0 using the default order specify BANK=PROCESS, SIMSCI. 2. When a file from keywords, either via the menu item File/Run Batch..., or from the DOS command line RUNP2 filename, and assays are being used in the simulation, the keyword file must explicitly state the TBP curve fitting method. Failure to do so will result in an input error message *** ERROR *** Starting with version 8.0.1, PRO/II keyword files must specify the curve fitting option on the ASSAY statement for calculated distillation points. To match the current GUI default specify the fit as ASSAY CURVEFIT=IMPR. To match simulations before version 8.0 using the default fit specify ASSAY CURVEFIT=VER6. When importing a file that lacks one or both of these selections, PRO/II will display a message box requiring the user to make an explicit selection. On file export, PRO/II will write the selections explicitly into the keyword file even if the defaults were selected. When opening files created in earlier versions of PRO/II, PRO/II will display a message box allowing the user a choice to accept whatever selections were previously made for consistency with that version, or to change to the newer, improved methods. With v8.0.3, the AMSIM add-on for simulation of amine sweetening has been upgraded to AMSIM v7.3 with the following new features: a. Activated Amine - Piperazine + MDEA (~5 wt% + ~40 wt%) Activated MDEA can be used wherever acid gases, such as carbon dioxide, hydrogen sulfide, carbonyl sulfide, or mercaptans, need to be removed to allow product gases to be processed properly, or to meet purchasers' specifications. Typical applications for the technology are ammonia synthesis gas plants and hydrogen/oxo synthesis gas plants as well as natural gas plants for sales gas, or LNG. Other applications include use in iron ore reduction units, ethane sweetening, and propane dehydration. Today, more than 200 aMDEA plants are either in operation, or under construction, worldwide.
