CPA EoS in NeqSim

The CPA-EoS

An example of using the the CPA-EoS from NeqSim is given in the following python script:

import neqsim
from neqsim.thermo.thermoTools import fluid, TPflash
from neqsim.thermo import dataFrame

system = fluid('cpa')
system.addComponent('methane', 0.5, 'mol/sec')
system.addComponent('water', 0.5, 'mol/sec')
system.setMixingRule(10) # Composition dependent and temperature dependent mixing rule
system.setPressure(10.0, 'bara')
system.setTemperature(25.0, 'C')

TPflash(system)

dataFrame(system)
