|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
|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.
|Chem-Engineering Services software supports heat exchanger engineering in design, evaluation
and rating modes for shell and tube, double pipe, thermosiphon, falling film and multi-tube types
of heat exchange equipment. The software provides optimized new designs, utilizing available
fluid pressure losses to achieve required heat transfer, while minimizing equipment cost, through
a powerful optimizer tool. Heat exchanger services are available for rating and evaluating the
capabilities of existing equipment for different service conditions or for entirely new applications.
The Heat Exchanger software provides rapid, accurate predictions for single-phase and
multi-phase heat transfer problems. Chem-Engineering Services software provides heat
exchanger services to clients for developing vibration analysis predictions, explaining existing
exchanger mechanical failure problems and to design reliable new equipment. Heat exchanger
engineering supplies clients with analyses of exchanger cost, size and weight for new and
existing equipment simulations.
This process engineering support software is used to support Chem-Engineering Services clients
needs, but is not licensed or offered for sale.
When existing plant heat exchanger equipment is operating with deteriorating performance or
limiting capacity, heat exchanger services provided by Chem-Engineering Services can provide
solutions to improve reliability, capacity and efficiency. Heat exchanger engineering services
provided by Chem-Engineering Services can provide highly optimized designs to fulfill business
goals and overcome existing equipment limitations and problems.
