is the perfect software tool for professionals in the chemical, natural
gas, and petroleum industries. You can
now easily and reliably
calculate thermodynamic and transport properties and use the results to:
- Use as an everyday tool to determine
mixutre physical properities.
- Size equipment and instrumentation.
- Check column and heat
- Solve difficult vapor-liquid
- Compute multi-component physical
properites for pressure relief valve calculations.
- Determine emissions for EPA
requirements for volatile organic compounds.
In addition, dew and bubble points can be
computed in accordance to API
gas professionals will appreciate the
which standard gas analysis problems can be solved.
Engineers no longer need an expensive
process simulator to compute properties. The basic routine
for vapor-liquid equilibrium calculations is the temperature-pressure
routine. All of the well known process simulation
applications available today use a T-P flash routine
modified to provide results which are a compromise between speed and
accuracy. Within these process simulation
speed is emphasized and accuracy is compromised.
Speed is emphasized simply because of the large number of T-P
needed to produce a reasonable, overall result for the process
simulation model...even for small, simple simulation
This is not the case
The T-P flash routine used in MixProps
was designed for one purpose...unparalleled accuracy. A
T-P flash is performed and the routine used generates a precise
regardless of machine time involved. These accurately
splits and component compositions, coupled with the PhysProps
database of pure component properties, generates an optimum set of
property data limited only by the pure component data and thermodynamic
model used. With MixProps,
inaccurate and compromised property values commonly found in process
is a thing of the past.
The output generated
consists of a comprehensive set of thermodynamic, thermophysical and
properties...all instantly available and in a wide variety of
Example Problems (the MixProps
installation contains the setup to these examples):

- Equilibrium K-Values
