HYSIM:  A history of innovation for chemical/hydrocarbon steady state 
        simulation since 1980 HYSIM was the first completely interactive
        simulator and the first simulator for the PC.  The current version
        of HYSIM, refined by more than a decade of modeling the toughest 
        applications found in the chemical and hydrocarbon processing 
        industries, provides a comprehensive selection of capabilities: a 
        complete Hyprotech thermodynamic library, oil characterization, a 
        wide range of unit operations and utilities including Tower design
        and rating. Interfaces are available to sizing packages such as STX,
        HTFS, BJAC, Supertarget, Column Target, and OLGAS. 
POLYSIM:  Windows polymer simulation based on POLYRED, the world's leading 
        polymer simulator POLYSIM, a modular, open-ended package for the
        computer-aided analysis and design of polymerization systems, is 
        based on POLYRED, already the world's foremost polymer process 
        simulator.  POLYSIM is a cooperative effort with Prof. Harmon Ray
        of the University of Wisconsin Polymerization Research Laboratory to
        develop a commercial PC version of POLYRED. This version features the 
        effortless yet powerful HYSYS graphical user interface under Windows. 
FLARENET:  Windows flare header network design and optimization FLARENET 
        facilitates the design and optimization of flare header networks and
        vent systems based on user specified limits for noise, back pressure 
        or mach number. Complex piping networks, with any number of relieving
        sources can be modeled. Pressure drop calculations are made using 
        single and two phase pressure drop calculations. Robust multiphase 
        thermodynamic models back up the physical property predictions used 
        by the pressure drop models. Sizing calculations determine either the 
        minimum size for a new vent system or sizing to relieve bottlenecks.
        Extensive internal databases, integration with external programs and 
        direct interfaces with HYSIM and HYSYS allow FLARENET to speed and 
        improve model development.
