Enhancement Of The Thermophysical Capability Of The Chemical Engineering Simulation System, Joydeep Banerjee
Enhancement Of The Thermophysical Capability Of The Chemical Engineering Simulation System, Joydeep Banerjee
Theses
The CHESS (Chemical Engineering Emulation System) is a generalized steady-state, sequential-modular chemical process simulation program. In this thesis, the thermophysical data prediction capability of CHESS has been expanded by: incorporating more accurate thermodynamic phase-behavior models, by utilizing these models in generating a wider range of thermophysical properties, and providing an updated and expanded database for pure-component physical properties.
The overall performance of the simulation system's thermophysical package has been evaluated using the study of a subprocess consisting of various rotational equipment modules.
In this work, the Chao-Seader liquid phase activity coefficient model has been reinstalled in conjunction with the original …

Theses
Chemical process simulation programs have become an indispensable tool to chemical engineers in the preparation of heat and material balances, and energy conservation studies. Since the 1960's several dozen process simulators have been developed which are in use today within companies and through computer service bureaus. Due to advances in the areas of unit operation analysis and thermodynamic relations, these programs require periodic modification. This thesis describes the programming modifications made to the Chemical Engineering Simulation System (CHESS) version 2.0, computer program. This undertaking was considered warranted since no improvements have been made to CHESS since its release in 1971. …
