1. Introducing OLI Flowsheet: ESP
AQSim
January 2018
Think simulation!

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

3. 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.

4. 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

5. 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.

6. 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?

7. 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

8. 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

9. *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
