This project continues to be the primary physical and chemical property resource for CPAS tools. The project provides supporting consultation and data resources on an as-needed basis. Results are available through a stand-alone tool called "Software to Estimate Physical Properties" (StEPP), which is being extended to a second version, "StEPP2," in this project.

The project also facilitates data exchange between various other CPAS tools. Ultimately, the goal is to create a general software-based data delivery system that will serve as an expandable framework for adding property estimation algorithms and third party-generated data resources.


The first-generation version of the software being developed under CPAS, called StEPP Version 1.0, has already been designed to provide data support to the Adsorption Design Software (AdDesignS) and Aeration Systems Analysis Program (ASAP) modules under the Environmental Technologies Design Option Tool (ETDOT) initiative led by Dr. David Hand of MTU. StEPP, an acronym for "Software to Estimate Physical Properties," will ultimately link to every other tool and module within CPAS that needs data for its calculations. Many of the CPAS tool development efforts now underway rely on a working, expanded StEPP program for their development, testing, and release. StEPP will also have value, apart from CPAS support, as a stand-alone program that efficiently and rapidly supplies engineers, scientists, and process designers with necessary physical property data.

To support the Adsorption for Recovery (AdRecover) and Multi-Component Distillation (MC-Dist) modules, StEPP2 (an updated version of the original StEPP program) will be linked to provide vapor pressures, activity coefficients, and Henry's constants for relative volatility calculations. StEPP2 also includes chemical, physical, and environmental reactivity data that will be useful in computing design comparison indices in the Environmental Fate and Risk Assessment Tool (EFRAT) being developed by Dr. David Shonnard.

The StEPP2 project team has supported the data requirements of the AdDesignS, ASAP, AdRecover, MC-Dist and EFRAT development projects throughout the project's existence. Data exchange has been promoted between the various CPAS tools, facilitating rapid evaluation of "clean" process designs.

The StEPP2 module under development will also feature stand-alone data display. Data sources for StEPP2 include tables of discrete data from AIChE/DIPPR Project 801, as well as data calculation and extrapolation methods, with a broad capability that includes infinite dilution thermodynamics, polarizability estimates, phase equilibrium algorithms, and transport properties. Among the pure component properties available in StEPP2 are: vapor pressure, molar volume at the normal boiling point, liquid density, activity coefficient, Henry's law constant, aqueous solubility, octanol-water partition coefficient, soil-water partition coefficient, and partitioning onto the organic carbon portion of biomass. The extent of use of DIPPR Project 801 data within StEPP2 is limited and conforms to licensing agreements between CenCITT and DIPPR.

Beta Version 2.0 of StEPP is nearing completion as the primary physical property server for CPAS. It will have the following features:
· Generic protocol for data delivery/export (export feature is now working and needs to be expanded to specific CPAS modules)
· On-line Help system (almost completed, being examined for errors)
· Fill database gaps with estimated values (ongoing)
· Test structure disassembly from SMILES (MOSDAP, "Molecular Structure Disassembly Program", completed; UNIFAC, Hine & Mookerjee, Lydersen, and Benson groups will be supported)
· Incorporate group contribution vapor pressure module developed by Andrew Loll, M.S. Graduate
· Database scrutiny (Statistical Quality Control, SQC, data checking to proceed through Spring 2000)
· Partial licensing of AIChE/DIPPR data for incorporation within StEPP2
· Supply physical property needs of the ETDOTs, EFRAT, and other CPAS modules (ongoing)

Expected Results:

Physical and chemical property measurements and estimations are central to virtually all environmental assessment and process design decisions. Despite the importance of property data, expertise in physical and chemical properties tends to be a specialization beyond the capabilities of most process and product designers. By being closely aligned with the Physical Property and Thermodynamics Research Group (P2TRG) in the MTU Chemical Engineering Department, this project is epected to continue to insure that this expertise is available and becomes incorporated into CPAS tools. The P2TRG also conducts two programs dealing with chemicals of environmental interest for the Design Institute for Physical Property Data (DIPPR®) of the American Institute of Chemical Engineers (AIChE).
