OLI Process Solutions

OLI ESP The Environmental Simulation Program (ESP) is a powerful but dated steady-state electrolyte process simulator. ESP has addressed simulated aqueous chemical processes for a wide range of markets. Success Stories Mix Manipulate Split Feedforward Separate Controller Neutralizer Sensitivity Absorber Reactor Stripper Exchanger Extractor Precipitator Incinerator ComponentSplit Bioreactor Compressor Clarifier Membrane (UF, RO) Electrodialysis Saturator Dehydrator Crystallizer ESP provides the engineer or scientist accurate answers to questions involving complex aqueous systems. Design, debottlnecking, retrofitting, troubleshooting and optimizing of existing or new processes is easy with ESP. Upstream waste minimization, as well as the waste treatment itself, is possible with ESP. Sensitivities The Sensitivity Block in ESP allows the user to determine easily the sensitivity of output results to changes in Block Parameters and physical constants. Hydrocarbons in ESP Both ESP's AQ and Mixed Solvent Electrolyte (MSE) models accept pseudocomponents and hydrocarbon components as part of process input.

ESP: flowsheeting and control Process flowsheeting with multiple recycles and control loops are allowed in ESP. Feedforward and feedback controllers and Manipulate blocks help to achieve process specifications. Biotreatment modeling in ESP Heterotrophic and autotrophic biological degradation is integrated with rigorous aqueous chemistry. Single or multiple substrates are allowed. Substrates may be specific molecules from the Databank or characterized by ThOD, MW or statistical stoichiometry. Simultaneous physical (e.g., air stripping) and chemical (e.g., pH, trace components) effects are applied. ESP provides for flexible configuration of biotreatment processes, including sequential batch reactors and clarifiers with multiple recycles. Dynamic simulation with control The dynamic response of a process can be studied using OLI's dynamic simulation program, DynaChem, to examine control strategy, potential upsets, scheduled waste streams, controller tuning, and startup/shutdown studies. Studies of pH and compositional control, batch treatment interactions, multistage startup and shutdown, controller tuning, multicascade and adaptive control are all possible. DynaChem comes with an OLI ESP license.

OLI Alliance Partners Now it is possible to combine the rigor of OLI’s electrolyte approach with your preferred flowsheet simulation package. When you need an electrolyte model within your flowsheet simulator, OLI recommends one of our Alliance Partner products By specifying OLI as a property package within any of our Alliance Partner products, you can accurately account for the electrolytes in your system. This technology uses the same OLI Engine found in OLI stand-alone products. Adding an expert to your staff - OLI! OLI supplies the rigor and the accuracy that you need when modeling electrolyte applications within your flowsheet. In addition, OLI simulation experts are available to answer your application building questions and help guide your electrolyte case setup Coming in 2008: OLI Pro Later this year, OLI will release OLI Pro, an OLI product that combines the Honeywell's UniSim Design shell with OLI electrolyte operations within this flowsheet environment. ESP users will be offered an evaluation copy of this software as an eventual replacement for ESP. OLI thanks Honeywell for the use of the UniSim Design shell for this OLI product.
