Abstract
A vessel is provided for collecting a process stream and fractionating the process stream into a liquid and gas phase in the vessel. Cooling may be provided by an internal bath and/or an external bath. The liquid phase retained in the vessel and the gas phase collected in lots from the vessel may be delivered to a lab for analysis.
Claims15
An apparatus for collecting a sample of a process stream comprising:
- a vessel including a top and at least one wall enclosing an open volume;
- an inlet to the vessel to allow a fluid sample stream to enter into said open volume and flash into liquid and gas phases;
- a shaft disposed in said vessel, said shaft including a gas outlet from the vessel and a port in communication with said vessel for said gas phase to enter said shaft to be fractionated;
- and
- a coolant reservoir disposed in said shaft proximate said gas outlet defining a passage between the coolant reservoir and the shaft through which said gas phase may travel to further condense lighter materials in said gas phase into said liquid phase.

An apparatus for collecting a sample of a process stream comprising:
- a vessel including a top and at least one wall enclosing an open volume;
- an inlet to the vessel to allow a fluid sample stream to enter into said open volume and flash into liquid and gas phases;
- a shaft disposed in a nozzle in the top of said vessel, said shaft including a gas outlet from the vessel and a gas port downwardly spaced from said gas outlet;
- and
- a coolant reservoir contained in said shaft proximate said gas outlet to further condense lighter materials in said gas phase traveling in a passageway between said coolant reservoir and said shaft into said liquid phase.
2 more elements
A process for collecting a sample from a process stream comprising:
- flashing a stream of sample into an open volume of a vessel to separate a liquid phase from a gas phase;
- collecting said liquid phase in said vessel;
- fractionating said gaseous phase while passing through a shaft that includes an outlet from said vessel to condense heavier components out of said gaseous phase;
- withdrawing said gaseous phase through said outlet from said vessel;
- and
- cooling said gaseous phase with a coolant reservoir contained in said shaft as it travels to said outlet to condense lighter materials from said gaseous phase.
