Override Henry's coefficient data

The Henry tab in the Method Data section contains a component grid for every possible solute-solvent pair in the Fluid Type. Each solute-solvent pair has a cell that indicates the status of the Henry's coefficient data:

• If the cell is blank, there is currently no data for the solute-solvent pair.

• If the cell has a green badge, the Henry's coefficient data is available and comes from the default or custom data banks.

• If the cell has a function icon , the Henry's coefficient data comes from the default or custom data banks, but the value is calculated from a correlation.

• If the cell has a blue badge, the Henry's coefficient data is available and comes from the user-specified (that is, locally overridden) data values on the Henry tab.

You can access the Henry tab only if the Fluid Type uses Henry's Law in its calculations (that is, in the Equilibrium Options section, the Use Henry's Law checkbox is selected).

Override the Henry's coefficient data

1. In the Fluid Editor, expand the Method Data section, and then select the Henry tab.

2. In the component grid, select the cells for the solute-solvent pairs whose Henry's coefficient data you want to change.

   The Henry's coefficient data for those solute-solvent pairs appears in the table on the Henry tab.

3. In the table, change the Henry's coefficient parameters as desired.

   See the equations preceding the table if you have questions on how the software uses each parameter in the calculations.

   A blue badge appears in the component grid for each solute-solvent pair whose data you modify.
