NUCON International provides steady state chemical process simulations using state of the art software (CHEMCAD). Thermophysical properties are based on the DIPPRĀ® (Design Institute for Physical Properties) database. In addition about 6000 pairs of binary interaction parameters are included for use with NRTL, UNIQUAC, Marqules, Wilson and Van Lear activity coefficients methods.



Flowsheeting tools allow ground up design of steady state processes. Models are based on rigorous thermophysical equilibrium.


Models can be changed and adjusted to predict the effect that the changes will have on operation.


Plant data can be fed into a simulation to increase the model's rigor. Sensitivity analysis can be used to improve performance.


Accurate models of process and safety related equipment will reduce your workload in complying with the increasingly complex regulations.
