VacuumDistillationModel..::..VacuumDistillation Method

This model is used to calculate the emissions associated with vacuum operations. The model assumes that air leaks into the system under vacuum, is exposed to the VOC, becomes saturated with the VOC vapor at the exit temperature, and leaves the system via the vacuum source.

The most important input parameter to this model is the leak rate of the air into the system. If the leak rate for a particular piece of equipment has been measured, then this leak rate can be used. On the other hand, if no leak rate information is available, EmitNJ will estimate the leak rate using the system volume entered by the user and industry standard leak rates for 'commercially tight' systems.

)

Parameters

initial
Type: Highpoint.Sage.Materials.Chemistry..::..Mixture
The mixture as it exists before the emission.
final
Type: Highpoint.Sage.Materials.Chemistry..::..Mixture%
The resultant mixture after the emission.
emission
Type: Highpoint.Sage.Materials.Chemistry..::..Mixture%
The mixture emitted as a result of this model.
modifyInPlace
Type: Boolean
If true, then the initial mixture is returned in its final state after emission, otherwise, it is left as-is.
controlTemperature
Type: Double
In degrees kelvin.
vacuumSystemPressure
Type: Double
In Pascals.
airLeakRate
Type: Double
In kilograms per time unit.
airLeakDuration
Type: Double
In matching time units.
