Experimental data for solvent/polymer systems are often given as either (Polymer mass fraction, Pressure) or (polymer mass fraction, Temperature) curves.
This function lets the user trace the cloud point curve at fixed temperature as a function of polymer mass fraction while the solvent ration is constant.
Calculating this curve needs some input from the user

Type
|
Optional
|
Description
|
Feed
|
Range of double
|
No
|
A range of cells with the feed
|
Direction
|
C# : string
|
No
|
Direction in polymer mass fraction. Valid input are:
•Up •Down |
InitialMassfraction
|
C# : double
|
No
|
Polymer mass fraction where the curve starts.
|
Temperature
|
C# : double
|
No
|
Fixed temperature.
|
MinimumPressure
|
C# : double
|
No
|
Is used when calculating the first point on the curve. Lowest possible pressure.
|
MaximumPressure
|
C# : double
|
No
|
Is used when calculating the first point on the curve. Highest possible pressure.
|
Output
|
C# : string
|
No
|
Defines the output for each point on the curve. See here for more information.
|
Components
|
C# : string
|
No
|
Give a list of component names.
Only those components are used in the calculations.
See here for more information
|
Units
|
C# : string
|
No
|
Set the units used in this calculation.

|
Distribution
|
C# : object
(Expect a range of double)
|
Yes
|
Gives a range with the distribution of the polymer. Can for example be used if 2 flash calculations are liked as 2 separation tanks.

|
BlockMassfraction
|
C# : object
(Expect a range of double)
|
Yes
|
Sets the block mass fractions in a co-polymer.

|
ProjectSheet
|
C#: object
|
Yes
|
Lets the user set the project sheet to use.

|
AdvUser
|
C# : object
|
Yes
|
Advanced used. Reserved for the user. For example it can be used to force the function update.
