WinSim, Inc. Design II Chem-Engineering Services uses WinSim Inc. Design II process simulation software to provide process engineering support for chemical plant modeling of existing processes, as well as for designing plant retrofits for production capacity and efficiency improvement. The software includes most unit operations of chemical engineering, supporting process engineering services for a wide variety of industrial and chemical plants. Tremendous time saving results from the use of Design II, allowing more time to evaluate plant improvement alternatives. The software simulation results are in very close agreement with other process simulator programs and the reports provide excellent support of detail of calculations for client project documentation. Design II provides extensive thermodynamic methods and fluid properties options for many chemical processes. |
Steam-ASSIST is Windows-based software designed to produce heat and material balances for entire steam systems dynamically when variables are changed. The program handles complex steam systems with multiple pressure levels, utilizing process steam, heating loads, steam turbines of both back-pressure and vacuum turbine types, vacuum steam surface condensing, boiler water pumping and deaerator heating systems. Steam-ASSIST uses a steam properties module to predict the steam and water thermodynamic properties from full vacuum to critical pressure and temperatures to 1200 degrees Fahrenheit. The software rigorously simulates the performance of individual turbines' drivers, assessing their steam requirements from point efficiencies or efficiency curves via Turbine Pow-r Rate-r. The software performs heat balances for blending the exhausts of turbines and let-down services, predicting header operating temperature and pressure conditions. Flash calculations are included for prediction of boiler blow-down recovery to lower pressure header systems. Steam-ASSIST integrates with drawing software to generate steam system flow diagrams dynamically as new calculations are performed. There is lno imitation of the amount of equipment that may be included in a simulation. The software was written to produce accurate steam system heat and material balance predictions for performance evaluations and for changes imposed by different operating conditions, and equipment modifications involved in plant assessment and retrofit design projects. |
Chem-Engineering Services process engineering software, Turbine Pow-r Rate-r, was developed to establish the performance of both back-pressure and vacuum exhaust steam turbines. The program incorporates the steam properties module from Steam-ASSIST for thermodynamic calculations including enthalpy, entropy, superheat and percent moisture for superheated steam vapor, saturated and two phase steam conditions. The process engineering support calculations include prediction of water rate for given supply steam conditions and efficiency; efficiency for given supply steam conditions and water rate; and, water rate and efficiency for given supply and exhaust steam conditions. The process engineering basis may include the prediction of steam requirement for a given power requirement, or power developed for a given steam flow. Thermodynamic properties predictions cover the entire range of steam pressure from full vacuum to critical pressure at temperature to 1200 degrees Fahrenheit. Turbine Pow-r Rate-r software is fully integrated into Steam-ASSIST software, and also exists in a stand alone version for process engineering support and performance assessment of all types of turbines in a plant steam system. |
Heat-r-Rate-r software was developed for furnace engineering support of thermal and mechanical design, rating and performance evaluation in convection section coil heat transfer applications for the Chemical Process Industry. The program can simulate the performance of existing convection preheat coils, as well as develop new designs, determining flue gas and process fluid pressure drop, heat transfer and maximum tube wall temperature rigorously, calculating row by row for given inlet conditions. In furnace engineering services simulating furnace design or actual performance, individual coil construction may be of complex designs, including mixing bare and finned surfaces together and variable fin densities and height. The program has all standard materials for all thermo-mechanical design and rating verification. Heat-r-Rate-r Software can be used in furnace engineering services to predict the performance for complete convection section preheat systems, simulating the operation of individual coils in a system as they interact with all others. Once a furnace and convection section has been modeled, alternatives can be explored for achieving optimum performance. Individual or multiple coils within a furnace can be replaced or modified and revised predictions can be quickly developed for the entire convection section preheat system, to show the performance improvement. The software incorporates rigorous fuel combustion calculations to develop flue gas composition and flow and adiabatic flame temperature required for heat transfer predictions. The software has been used at many plant sites to rapidly analyze the benefits from convection coil cleaning, modification or replacement in aging furnaces. |
