VacuumDistillationWScrubberModel..::..VacuumDistillationWScrubber Method

This model is used to calculate the emissions associated with vacuum distillation. The calculation of the emission from the operation is identical to that for the Vacuum Distill model. This model incorporates the effect of the vacuum jet scrubbers into the emission calculation. The vacuum jet scrubbers are used to condense the steam exiting from the vacuum jet but they also condense solvent vapors through direct contact heat exchange.

The assumptions of the new model are similar to that of the existing vacuum distill model. Air leaks into the system under vacuum and becomes saturated with solvent vapors. With the vacuum distill model it is assumed that condensation of some fraction of these vapors occurs in the primary condenser and any uncondensed vapor is exhausted to the atmosphere (via control devices, if any). With this model, the vacuum jet scrubber acts as the final control device, assuming that a vacuum jet is being used to evacuate the system. The vacuum jet scrubber condenses vapors, which remain uncondensed by the primary condenser, through direct contact heat exchange with the scrubber water.

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.
systemPressure
Type: Double
In Pascals.
airLeakRate
Type: Double
In Kilograms per time unit.
airLeakDuration
Type: Double
In matching time units.
