ConstantMassExpansion

Top  Previous  Next

Constant mass expansion (also called constant composition expansion) examines how a feed behaves volumetric related to the volume at the saturation point.

The user has to give a pressure range and a temperature. The function will then calculate the volume at each point and report them relative to the saturation point volume.

 

Description of the function argument list

Input

Argument

Type

Optional

Description

Feed

Range of double

No

A range of cells with the feed

SaturationTemperature

C# : double

No

Temperature used in saturation point calculation

TemperatureList

Range of double

No

One column with a number of rows given the list of temperatures to use in the flash calculations

PressureList

Range of double

No

One column with a number of rows given the list of pressures to use in the flash calculations

Output

C# : string

No

Defines the output. (Note currently unused, so just leave blank)

 

Components

 

C# : string

 

No

Give a list of component names.

Only those components are used in the calculations.

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.
