<p>Most thermodynamic models have binary interaction parameters which are fitted to match experimental data. Always check if the selected thermodynamic model has interaction parameters for the compounds in the simulation, if required. To view the list of IPs, open the Property Package Configuration Window and go to the <b>Interaction Parameters</b> tab.<br />

</p><br />
<h2><span class="mw-headline" id="Models_by_System_Type">Models by System Type</span></h2><br />
<h3><span class="mw-headline" id="Non-polar_gases_at_low_pressures_.28.3C_10_atm.29">Non-polar gases at low pressures (&lt; 10 atm)</span></h3><br />
<p>Use the Raoult's Law Property Package. It assumes that both phases (gas and liquid) are ideal.<br />
</p><br />
<h3><span class="mw-headline" id="Non-polar_gases_at_high_pressures_.28.3E_10_atm.29">Non-polar gases at high pressures (&gt; 10 atm)</span></h3><br />
<p>Use one of the Equation of State models like Peng-Robinson, Soave-Redlich-Kwong and PRSV2. <br />
</p><br />
<h3><span class="mw-headline" id="Polar_gases_at_high_pressures_.28.3E_10_atm.29">Polar gases at high pressures (&gt; 10 atm)</span></h3><br />
<p>Use the PRSV2 Property Package. Check if it has the required parameters for your system as DWSIM lacks many parameters for this model. If it doesn't, fallback to an EOS model like PR or SRK.<br />
</p><br />
<h3><span class="mw-headline" id="Systems_with_high_Hydrogen_content">Systems with high Hydrogen content</span></h3><br />
<p>You can use the Chao-Seader, Grayson-Streed or Lee-Kesler-Plöcker model. The LKP model is very slow but can be more reliable depending on the system. The LKP model is very sensitive to the interaction parameter values being used.<br />
</p><br />
<h3><span class="mw-headline" id="Air_Separation_.2F_Refrigeration_systems">Air Separation / Refrigeration systems</span></h3><br />
<p>Use the CoolProp or FPROPS Property Package.<br />
</p><br />
<h3><span class="mw-headline" id="Steam.2FWater_simulations">Steam/Water simulations</span></h3><br />
<p>Use the Steam Tables Property Package.<br />
</p><br />
<h3><span class="mw-headline" id="Polar_chemicals">Polar chemicals</span></h3><br />
<p>Use one of the activity coefficient models like NRTL or UNIQUAC. If no interaction parameters are available for your system, you can fallback to one of the UNIFAC-type models. Modified UNIFAC (NIST) is recommended.<br />
</p><br />
<h3><span class="mw-headline" id="Salt.2FWater_systems">Salt/Water systems</span></h3><br />
<p>Use the Seawater Property Package.<br />
</p><br />
<h3><span class="mw-headline" id="Aqueous_Electrolytes">Aqueous Electrolytes</span></h3><br />
<p>DWSIM has limited support for aqueous electrolytes due to the lack of model parameters. You can try the Extended UNIQUAC model, but be ready for many convergence errors. It may or may not work. If you don't need information about pH and/or don't care about precipitation of solids, you can always use one of the available activity coefficient models instead.<br />
