Preliminary results
Project completion estimate
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.

6. Phase 2 proposal Gain insight into the overall silica removal process
Beyond solubility
Gain insight into the overall silica removal process
Pure-phase vs. solid-solution precipitation
Silica adsorption onto magnesium hydroxide surfaces
Solids inclusion within the magnesium hydroxide lattice
Reaction kinetics and mass transfer limits
All of the above
Most often when you work with OLI, you work through AQSim. Business development directors for OLI. Office in OLI, work closely together. Mission…OLI to further electrolyte science, AQSim to empower clients to solve water chemistry applications. AQSim works exclusively with OLI.

7. Phase 2 questions How significant is each mechanism?
Where should kinetics and mass transfer be applied?
What empirical data is available / needed?
What are successful and achievable milestones in this research project?

8. Phase 2 approach Section 1: More data needed
Collection and analysis of literature data
Surface complexation
Mass transfer
Reaction kinetics
Collection and analysis of plant data from members
Deliverable  phenomena versus kinetics assessment with modeling recommendations

9. Phase 2 approach (continued)
Section 2: laboratory data to plant data
Quantitative analysis of lab data
Determine how to fill the gap moving to plant data
Deliverables
Standardized coefficients applied to an equilibrium-based steady state simulation model.
Optimizer tool requirements to be used within an existing simulator
OLI is found anywhere that water is present. The team of thermodynamists have created a broad database to be used in many markets. The software is general, you give it meaning by defining your chemistry.

10. Success depends on data!
Empirical data available directly from COSIA
Empirical data available from members particularly plant data
Reports from COSIA-funded or member-funded researchers
Exhaustive literature search / data mining on silicate chemistry (beyond thermodynamics)
Surface complexation, mass transfer, reaction kinetics
OLI is found anywhere that water is present. The team of thermodynamists have created a broad database to be used in many markets. The software is general, you give it meaning by defining your chemistry.

11. Q/A on Phase 2
Good slide for mechanical eng who wonder why do process simulation.
