OLI ESP 9.6

OLI ESP (Electrolyte Simulation Program) by OLI Systems, Inc. is a steady-state process simulator purpose-built for systems with aqueous and mixed‑solvent electrolytes. It combines rigorous thermodynamic models with a comprehensive databank to help engineers design, troubleshoot, and optimize processes where water chemistry, salts, acids, bases, and organics interact—often with precipitation, scaling, or complex speciation.

Key capabilities:

• Rigorous electrolyte thermodynamics using OLI’s AQ and Mixed‑Solvent Electrolyte (MSE) models
• Extensive databanks covering thousands of ions, molecules, and solid phases relevant to industrial chemistry
• Multiphase equilibrium calculations across aqueous, vapor, solid (precipitates/scales), and non‑aqueous liquid phases
• Detailed speciation, pH and redox analysis, saturation indices, and scaling tendency predictions (e.g., CaCO3, BaSO4, CaSO4, SiO2)
• Flowsheeting with common unit operations (mixers, splitters, reactors, heat exchangers, separators, crystallizers, absorbers), including recycles and convergence
• Property predictions for electrolyte systems (activity and osmotic coefficients, densities, viscosities, heat capacities, enthalpy/heat effects)
• Scenario, sensitivity, and case studies for titration, blending, and operating envelope exploration
• Clear reporting and visualization to compare design options and operating conditions

Typical applications:

• Water treatment and desalination, including brine management and antiscalant strategy
• Oil and gas production and processing, including sour systems and produced‑water handling
• Power generation, geothermal, mining and metals, and specialty chemicals where scaling and speciation control are critical

Benefits:

• Predict and mitigate scaling and precipitation before they impact operations
• Reduce chemical consumption through targeted, data‑driven optimization
• Improve uptime and product quality by understanding electrolyte behavior under real process conditions

OLI ESP brings high‑fidelity electrolyte modeling into a practical flowsheet environment, enabling informed decisions for complex, chemistry‑driven processes.
