ProcesSimO 1.0
|
ProcesSimO™
software includes a drying gas stream, a drying material
stream and 19 unit operations, namely solid dryer, liquid dryer, cyclone, air filter,
bag filter, electro-static precipitator, wet scrubber, scrubber condenser, fan, compressor,
steam jet ejector, pump, valve, heater, cooler, heat exchanger (which can be used as an
evaporator), liquid-vapor separator, mixer and tee. It also includes a logical unit
operation, recycle, to simulate recycled gas or material stream. In addition to heat/mass/pressure
balance calculations in all the unit operations, ProcesSimO™
also contains a simple dryer scoping model, a detailed cyclone rating model as well as simple and
complex heat exchanger rating models for single phase heat transfer.

ProcesSimO™ can be used to model a drying process, an evaporation process, or a combined
evaporation and drying process. Using the streams and unit operations provided by the
software, users can construct any drying and evaporation related processes they wish to
model, design and analyze. They can also explore different arrangements of unit operations
and experiment with different operating conditions to optimize their designs and operations. Not only can the software simulate
almost any typical drying and evaporation related process, but also the recycled
exhaust gas stream and product material stream in a drying process.
ProcesSimO™ has a complete unit conversion system. Users can convert the inputs
and outputs of a large flowsheet from one set of units to another with just one click.
Engineers can use ProcesSimO™
to design drying and evaporation related plants. Based on
design requirements they can quickly layout the heat/mass/pressure balance calculations
and obtain the necessary process parameters such as the air flow rate
of a dryer, the capacity and power input of a fan, the heating duty of a heater, etc.
They then can choose equipment according to the simulation results. They can also easily
layout an existing plant on a flowsheet and optimize its operation.
University professors will find that ProcesSimO™
is an efficient tool for undergraduate
and postgraduate students to do projects for chemical engineering/ unit operations/ food engineering
and related courses. With this software package students can do what-if analysis which would
otherwise take an unrealistically long time to accomplish. It can also be used as a teaching
tool to show students the effects of input parameters on the output parameters for a typical plant.

Version 1.0 of ProcesSimO™ currently covers only the air-water system and is used mainly
for heat and mass balance calculations. Extension to other gas-organic liquid systems,
to superheated steam drying, to drying related equipment rating as well as to equipment
selection will be provided in future releases.
ProcesSimO™
has a friendly and intuitive user interface with maximum protection
to prevent users from making simple mistakes. It also has an effective tutorial to
teach users step by step how to use the software to simulate typical drying and
evaporation related processes. Users of ProcesSimO™
will require minimal
self-training and effort to use it effectively.

A humidity chart and a unit converter are also included in ProcesSimO™ as utilities.
The humidity chart utility can be used to visualize either the state of a drying gas or
an isenthalpic drying process. The unit converter utility covers all chemical engineering
units. Using the mouse, you can drag the state of the gas to different
positions on the chart, and the table variables will instantly be updated. Conversely,
you can modify the value of a variable in the table, and the position of the gas
state on the chart will change accordingly. The intensive calculations required
when modeling a drying process such as the states of moist gas for convective dryers
(the majority of all industrial dryers) or special state variables (wet-bulb temperature,
absolute and relative humidity) are now much easier to perform. It's time to throw
away the ruler and the paper psychrometric charts! |

In addition to modeling a variety of drying unit operations, ProcesSimO™
can also model unit operations typically used in particulate matter (PM) control
technologies such as cyclone separators, bag houses (also known as fabric filters),
and electrostatic separators (ESP). The user can input key design features of the
device such as PM separation efficiency, inlet and outlet mass loadings (grains/ft^3
or mg/m^3), pressure drop, and collection area. Using ProcesSimO™,
the user can add a selected PM control technology downstream of the drying equipment
to separate the particulates that may be generated from the drying process and carried
by the drying gas stream.
