Abstract

A system for on-stream sampling of pressurized process gas such as natural gas or the like, said system optimized for use with pressurized process gas having liquid entrained therein, or otherwise referenced as “wet”. In the preferred embodiment, a probe and method of sampling is contemplated to provide linear sample of fluids from a predetermined of said fluid stream. Further taught is the method of preventing compositional disassociation of a gas sample having entrained liquid utilizing a probe having a passage formed to facilitate capillary action in fluid(s) passing therethrough. The present invention teaches a unique and innovative tube bundle with a separate power cord integrated therein to power a heated vaporizer, pressure regulator or other modular conditioning or other electrical component, the tube bundle of the present invention thereby dispensing with the need for a separate power cord, while providing higher capacity than prior art systems.

Claims

1. A fluid sampling system for a wet gas fluid stream, comprising:

a sample probe consisting of a capillary flow path;

a modular conditioning component formed to receive flow from said sample probe via said capillary flow path, so as to provide a fluid sample;

a tube bundle;

a separate power cord within said tube bundle,

a tube bundle boot mounted to a bracket of a modular sample system,

said tube bundle formed to engage said tube bundle boot such that said power cord electrically engages a power cord receiver, so as to provide electricity to said modular conditioning component, so as to facilitate the processing of said fluid sample.

2. The method of claim 1, wherein said fluid sample comprises a multi-phase gas.

3. The method of claim 2, wherein said tube bundle boot comprises a power cord receiver for receiving and slidingly engaging said power cord so as to receive electricity therefrom.

4. The method of claim 1, wherein said sample probe utilizes said capillary flow path to facilitate capillary action in wet gas flowing therethrough, so as to prevent disassociation of said wet gas and provide a composite representative sample of said fluid stream.

5. The method of claim 4, wherein said tube bundle boot is formed to transfer power from said tube bundle to said modular conditioning component, heating same, providing a heated component;

and wherein said heated component is formed to receive said composite representative sample.

6. The method of claim 5, wherein said heated component is formed to vaporize entrained liquids, providing a single-phase sample.

7. The method of claim 1, wherein said conditioning component comprises a heated pressure regulator.

8. The method of claim 1, wherein said conditioning component comprises a vaporizer.

9. The method of claim 1, wherein said sample probe comprises a linear slot.

10. The method of claim 9, wherein said sample probe comprises a conduit formed to receive flow from said linear slot.

11. The method of claim 10, wherein said linear slot and said conduit are sized to facilitate capillary action in wet gas flowing therethrough, so as to prevent disassociation of said wet gas flowing therethrough.
