VacuumDistillationModel Methods

The VacuumDistillationModel type exposes the following members.

Methods


  Name Description
Public method Equals(System.Object)
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Protected method EvaluateSuccessOfParameterReads
This is called after all parameter reads are done, in a late bound model execution. It forms and throws a MissingParameterException with an appropriate messasge if any of the parameter reads failed.
(Inherited from EmissionModel.)
Protected method Finalize
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object.)
Public method GetHashCode
Serves as the default hash function.
(Inherited from Object.)
Protected method GetSystemPressure
Gets the system pressure from the parameters hashtable. It may be stored under the PN.SystemPressure_P or failing that, the PN.FinalPressure_P key.
(Inherited from EmissionModel.)
Public method GetType
Gets the Type of the current instance.
(Inherited from Object.)
Protected method MemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Protected method PrepareToReadLateBoundParameters
Performs initial bookkeeping in support of determining if an error occurred while reading late-bound parameters for an emissions model.
(Inherited from EmissionModel.)
Public method Process
One-size-fits-all API for all Emission Models, so that the Emissions Service can run an emission model that it has never seen before.

In order to successfully call the Vacuum Distillation model on this API, the parameters hashtable must include the following entries (see the VacuumDistillation(...) method for details):

"AirLeakRate", "AirLeakDuration", "SystemPressure" and "ControlTemperature". If there is no entry under "VacuumSystemPressure", then this method looks for entries under "InitialPressure" and "FinalPressure" and uses their average.

Protected method ReportProcessCall
Creates a string that reports the process call, logging it to Trace.
(Inherited from EmissionModel.)
Public method ToString
Returns a string that represents the current object.
(Inherited from Object.)
Protected method TryToRead(Double%, String, Hashtable)
Attempts to read a parameter by name from the late-bound parameters list, providing an error message if the parameter is missing.
(Inherited from EmissionModel.)
Protected method TryToRead(Hashtable%, String, Hashtable)
Attempts to read a parameter by name from the late-bound parameters list, providing an error message if the parameter is missing.
(Inherited from EmissionModel.)
Protected method TryToRead(Mixture%, String, Hashtable)
Attempts to read a parameter by name from the late-bound parameters list, providing an error message if the parameter is missing.
(Inherited from EmissionModel.)
Public method VacuumDistillation
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.
