1. RO Membrane in OLI Flowsheet: ESP
AQSim
October 2017
Think simulation!

2. Quick introduction Water Chemistry Applications Electrolyte Science
- Process simulation - Corrosion simulation
Software tools
- OLI training - OLI Simulation Studies - OLI sales

3. OLI solutions in three areas
Electrolyte Chemistry analysis Process simulation Aqueous Corrosion modeling
Understand in-depth behavior of the electrolytes in your system
Solve problems involving multiple blocks + recycle, or multi-stage columns
Determine the corrosivity of a chemistry in contact with a metal surface

4. 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

5. RO Membrane simulation
Reverse Osmosis (RO)
The basis of many water treatment schemes
Vendor software
To determine which membrane
Missing rigorous water chemistry model
Specific water chemistry effects must be estimated
Several iterations necessary
Between electrolyte software and vendor software to determine the potential effect of a specific membrane

6. Value added with OLI’s RO
Membrane library that can be extended
Library for your organization
Screening different membranes made easy!
Approach
“Tune” the membrane to vendor specs in OLI
Substitute “vendor salt (e.g., NaCl) with specific water chemistry
Replaces an earlier RO model in ESP Orig
No membrane library
Difficult to use

7. OLI’s RO & Membranes: Status
Reverse Osmosis
The first membrane block implemented
