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

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

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

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

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

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

OLI’s RO & Membranes: Status Reverse Osmosis The first membrane block implemented Beta testers? Being sought for 4Q 2017 beta Feedback from beta Incorporated 1Q 2018 Other membranes being considered Seeking client feedback NF, UF, FO are candidates
