Process
Simulation
One
of the many tools which DeNovo-nv. utilizes is CHEMCAD III for process
simulation. Through this system DeNovo-nv. can do complete modeling
of Reactors, Incinerators, Distillation Columns, Flash Towers Scrubbers
and much more. With this package heat exchangers and columns are
easily sized. Continuous " What If " scenarios can be
run quickly and cost effectively to determine the impact of any
given change in pressure, temperature, flow rate, material balance
or any other process variable or constraint. Process changes can
be made on the simulation to determine effectiveness before actual
construction in the field. Different packing could be tried in a
column to determine its impact on the process. Criss-crossing exchangers
could be tried for energy savings. Questions such as "where
should we place the vent stream if we want to try to recycle it?"
can be asked and tried.
In addition to new system designs, the program is an excellent tool
for trouble shooting existing systems when the physical plant parameters
are put into the simulator. The entire model is flow sheet interactive.
Unit operations are easily added to and removed from the flow sheet.
With the flow sheet being built on the computer, picking standard
unit operations from the program, and then interconnecting the streams,
rigorous calculations can then be done based on the thermodynamic
data chosen. Necessary data which is not part of the available library
is easily added and stored for future use.
Depending on output requirements, the system can be designed to
evaluate gross process effects where only large group impacts are
reviewed, or the system can analyze elemental effects where multiple
levels of the basic chemistry can be reviewed to determine the resultant
emissions breakdown of a given process stream by individual components.
