Argument

Type

Optional

Description

Feed

Range of double

No

A range of cells with the feed

Pressure

C# : double

No

Pressure, default unit: Bar

PhaseFraction

C# : double

No

Phase fraction, mole based value

FlashType

C# : string

No

Defines the number of phases to look for. Valid input are:

2: Will maximum look for 2 phases

Output

C# : string

No

Defines the output. See here for more information.

 

Components

 

C# : string

 

No

Give a list of component names.

Only those components are used in the calculations.

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.

AdvUser

C# : object

Yes

Advanced used. Reserved for the user. For example it can be used to force the function update.

Examples:

 

Lets do a calculation on a system with three components at 1 Bar and 0.1 phase fraction. The solvent mass fractions are given in the range: B3:B5

We want temperature and the composition of phase 1 and 2 as the output

 

=Flash_PB(B3:B5, 1, 0.1, "T,C(1),C(2)")
