H 3PO 4 are available for selection from the Composition > Feed Chemical Details menu
(Figure 5-35). The Feed Chemical Details menu is as shown in Figure 5-36. For the
selected chemical, two input parameters of % purity and density of chemical solution at
the selected %-purity are required. The chemical and corresponding state variables which
are set in the feed are shown in
