General Description

The AQSol solver is called to determine the state of a SysCAD stream. The composition, temperature and pressure of the 'Feed' stream are based on the feed to the unit. The unit will then determine the equilibrium conditions of the resulting stream.

  • This model is designed to simulate a reverse osmosis membrane process, often used in water treatment, especially for desalination of sea water.
  • The user may specify the yield and efficiency of the process, as well as the outlet pressure requirements.
  • The unit expects the feed to be free of solids. If solids are fed to the unit, the user will receive a warning and any solids will be sent to the Brine stream.
  • If a vent stream is connected, then all gases will exit via the Vent. If gases are present and there is no vent connection then the user will receive a warning and all gases will be sent to the Brine stream.

Notes

  1. The user MUST have added and configured a AQSol Model Configuration unit in the SysCAD project before this unit can function.
  2. The user MUST have installed a version of AQSol on their computer to make use of the AQSol functionality in SysCAD. Please see www.phasediagram.dk for more information.

Diagram

RO Unit.png

  • The diagram shows default drawing of the Reverse Osmosis unit with connecting streams.
  • The physical location of the streams connecting to the unit is unimportant. The user may connect the streams to any position on the unit.
  • When inserting a Reverse Osmosis unit into a flowsheet, the user may choose a different symbol from the menu.

Inputs and Outputs

Output
Number of Connections Description
Min Max
Feed 1 Required Input 1 20 Inlet liquid feed stream to the unit, usually water with dissolved salts.
FeedProdSide Optional Input 1 20 Inlet liquid feed stream to the product side of the membrane. This is useful for modelling numerous technologies including forward osmosis, diffusion dialysis, etc.
Product Required Output 1 1 Outlet product stream of the unit, usually purified water.
Brine Required Output 1 1 Outlet brine or waste stream of the unit.
Vent Optional Output 0 1 Optional gas outlet from the unit.

The AQSol Reverse Osmosis model can be incorporated into a SysCAD flowsheet, it can be connected with SysCAD inlet and outlet streams.

Behaviour when Model is OFF

If the user disables the unit, by un-ticking the On tick box, then the following actions occur:

  • All feed material will flow straight out of the Brine outlet;
  • No material will flow out of the Product or Vent outlets;
  • No sub-models will be called.

So basically, the unit will be 'bypassed' without the user having to change any connections.

Model Theory

The AQSol Reverse Osmosis Model uses the AQSol algorithms and data to determine the status of the aqueous solution.

Mapping of the SysCAD to AQSol streams is done via Species Mapping.

The AQSol Reverse Osmosis can be incorporated into a SysCAD flowsheet, it can be connected with SysCAD inlet and outlet streams.

  1. User connects the AQSol Reverse Osmosis with SysCAD input streams,
  2. The SysCAD feed stream(s) using SysCAD species is converted into AQSol "Input" using AQSol Species. The species mapping is defined in the corresponding AQSol Model Configuration unit model.
  3. The AQSol Reverse Osmosis calls the AQSol algorithms to determine the status of the mixture using the converted AQSol "input" data.
  4. The AQSol results are displayed in the "output" tab using AQSol species.
  5. The results are converted back into SysCAD species. Please see Species Mapping for more information.

NOTES:

  • The Input, Output and Diff tab pages are displayed using AQSol species, as defined in the AQSol database file (.dat) specified in the corresponding AQSol Model Configuration unit model.
  • The species used in the SysCAD project are shown on the optional Sp pages, shown as part of the QFeed, QBypass, QUnmapped, QRxnProdBypass and QProd pages.
  • The calculations performed are similar to using AQSol directly, except the contents of the SysCAD stream are mapped to equivalent AQSol species using the settings defined in the AQSol Model Configuration unit model. Please see www.phasediagram.dk for more information.
  • Important note on energy balance: The Reverse Osmosis feed enthalpy in the AQSol context is determined from the equilibrium composition of the Reverse Osmosis feed as calculated by AQSol at the SysCAD stream temperature and pressure. If one or more of the SysCAD streams feeding the AQSol Reverse Osmosis are far from equilibrium and will generate significant heat upon reaction (e.g. a stream containing unreacted HCl and NaOH, for example), the AQSol calculated heat of reaction will be incorrect. In this case, the unreacted species should be reacted prior to feeding them to the AQSol Reverse Osmosis. Ensure that both the AQSol and SysCAD energy balances are reasonable. See TCE Enthalpy Reporting for more details.

WorkFlow

The suggested workflow for configuring the model is:

  1. Make sure the project contains at least one of the AQSol Model Configuration model, and the model is loaded with the correct AQSol database you would like to use for the AQSol Reverse Osmosis model.
  2. On the AQSolReverseOsmosis tab page, configure the model - methods, pressures, etc.
  3. On the TCE tab page, select the correct ChemModel (to match step 1) (Note: In older builds, this selection was made on the AQSolReverseOsmosis tab page).
  4. Select other TCE options (Bypass, CFE, etc.)
  5. Perform an equilibrium calculation by pressing Solve in SysCAD.
  6. The Results are displayed in the AQSolResults and Output tabs.
  7. Check and fix any species mapping issues. (AQSol resulting species may change if the operating conditions change, so it is likely a change of temperature or feed composition will result in different AQSol species.)

IonPerm tab page

This is only visible if the EffMethod is set to Ionic Permeability. Ion permeability is determined based on the total ions in the solution.

Specify permeability of ions through membrane
Based upon total amount of each ion in the solution (complete breakdown)
Ion.Perm Input Ion permeability is specified based upon the total ion in solution. Ion is the name of the ion from the AQSol model as loaded.
CO3-2.Perm Example The total carbonate is calculated after all carbonate ions are broken down into their constituent parts. This means that the total carbonate is obtained from the sum of CO3-2 ions in solution and the breakdown of HCO3- (where HCO3- breaks down into H+ and CO3-2). Following this, adjustments are made to the acidity or basicity of the solution on both sides of the membrane to ensure charge neutrality.
