OLI software can calculate vapor-liquid-liquid-multiple solid equilibria for a single point of equilibrium or for a survey of points that allows the study of trends.
OLI can also be used for multi-stage calculations or multi-unit processes with recirculation and controllers.
OLI has "OLI only" or "OLI primary" simulation choices for flowsheets.
OLI also offers the OLI Engine "under the hood" in a variety of flowsheet simulators, via our Alliance Products.
OLI Process Simulation
Getting the wrong answer is worse than no answer at all
Full flowsheet capabilities
Building blocks in electrolyte flowsheet simulation are the same as in hydrocarbon flowsheet simulation. Units include tanks, mixers, tees, 2-and 3-phase separators, heaters, coolers, air coolers, exchangers, LNG exchangers, pumps, compressors, valves, relief valves, absorbers, distillation columns. Electrolyte specialties include crystallizers, precipitator, neutralizer and solids separation.
Adjuster, set, and recycle blocks combine with material and heat streams for maximum process definition flexibility. Electrolyte process flowsheeting includes multiple recycles and control loops. Feedforward and feedback controllers and Manipulate blocks help to achieve process specifications.
Electrolyte and hydrocarbon thermodynamics
Hydrocarbons can be included aqueous processs streams and they are effectively modeled within OLI's electrolyte thermodynamic frameworks. In the AQ model, hydrocarbons are modeled using the SRK equation of state for both the gas phase and the hydrocarbon-rich nonaqueous liquid phase. In the MSE model, the SRK equation is used for the gas phase whereas both the aqueous and the hydrocarbon-rich liquid phases are modeled using the MSE activity coefficient model.
Both ESP's AQ and Mixed Solvent Electrolyte (MSE) models accept pseudocomponents and hydrocarbon components as part of process input.
