vtTemp1(5) = 1173.15
vtProp1(0) = 0.01
vtProp1(1) = 0.03
vtProp1(2) = 0.2
vtProp1(3) = 2
vtProp1(4) = 3
vtProp1(5) = 5
sulKey = 11029
sulBulk = 2
feed.ShiftPropCurveIFace sulKey, 6, vtTemp1, vtProp1,
sulBulk
In the above example, the sulfur property of the feed stream is
shifted to the value 2.0. The algorithm will use 6 data points
(vtTemp1 as TBP end Points and vtProp1 as Property Value).
ManipulateCompositionIFace
This function takes in distillation information and light end yield
information and determines the composition of a stream.
ManipulateCompositionIFace (bsCompBasisVarType As String,
bsTargetDistType As String, vtTargetTemps As Variant,
vtTargetYields As Variant, vtTargetLEComp As Variant,
vtTargetLECompId As Variant)
Inputs:
Before execution of this function, feed composition must be
empty.
bsCompBasisVarType Composition Basis (“VolFrac”, “MassFrac” or
“MoleFrac”)
bsTargetDistType Distillation Basis ( “TBP”, “D86”, “D2887” or
“D1160”)
vtTargetTemps Distillation temperature end points (in degree
C)
vtTargetYields Cumulative percentage distillation yields (as in
basis bsCompBasisVarType)
vtTargetLEcomp Fractional light end yields (as in basis
bsCompBasisVarType) for all the components
present in the stream
vtTargetLECompId Light end component IDs (Component Index for
all the components present in the stream)
