Introducing OLI Flowsheet: ESP AQSim January 2018 Think simulation!

Agenda Introduction OLI Flowsheet: ESP overview Resources available Seawater evaporation Water treatment example

Introducing OLI Who are we? What are we? Global thought leader A collection of like-minded specialists Global thought leader in electrolyte systems, modeling and simulation In business 45 years, core competency is electrolyte thermodynamics research and development. (consider size of company of prospect) 8 full time electrolyte physical chemists & thermodynamicists. From this work we have developed expertise in experimental data mining and contracting labs for data, in process simulation and mathematical techniques. electrolyte and simulation experts. Marshall was at Exxon and became interested in challenging mathematical convergence models. Electrolytes have very challenging mathematical behavior. When you work with OLI you work primarily work through SW. Sometimes you will work with OLI to extend the model or the data.

Introducing OLI What do we do? Global thought leader Deliver innovation throughout the process industry, ensuring safe, secure process deliverables using proprietary software and solutions 47 years in business Core competencies in Electrolyte thermodynamics Process simulation Aqueous corrosion simulation

Result: Simulation Power Duplicate your physical process ... using mathematics and chemistry Focus laboratory / pilot plant tests ... eliminate trial and error … hone in on the likely target Anticipate process changes before they occur ... reduce cost, process upsets, and risk … make informed recommendations to optimize your process Good slide for mechanical eng who wonder why do process simulation.

OLI Answers Electrolyte Chemistry analysis Process simulation Aqueous Corrosion modeling Scaling predictions / phase distribution for gases, salts, ions in solution Calculate conditions across multiple blocks + recycle, or multi-stage columns Screening materials: will my chemistry cause corrosion on these metal surfaces?

Focus on process simulation OLI Flowsheet: ESP When electrolytes are primary When OLI thermodynamic methods are sufficient Designed for electrolytes OLI Alliance Partner products Couple OLI thermodynamics with other methods Lessen the learning curve to using OLI AspenTech, Honeywell, Andritz, PSE, SimSci OLI Engine in SysCAD, OLI Engine in CADSIM

OLI Flowsheet: ESP content V9.5.4 Available Blocks Sixteen generalized blocks with many configurations Standard: Mixer, separator, flow splitter, settler, filter, heat exchanger Advanced: Neutralizer, component splitter, compressor, turbine, RO membrane Multi-Stage: Absorber, distillation (including mass transfer limited) Control: Controller, recycle, manipulate, senstivity Further development Calculator block, electrolyzer, extractor, precipitator, & others

*New* RO membrane simulation Membrane library that can be extended Library for your organization Screen different membranes made easy! Beyond vendor software “Tune” the membrane to vendor specs in OLI Substitute “vendor salt” (e.g., NaCl) with your specific water chemistry Replaces an earlier RO model in ESP Orig
