Technical Examples

A system for obtaining a representative sample of a natural gas stream, particularly a stream which is at or below its hydrocarbon dew point temperature (H.C.D.P.). The preferred embodiment of the present invention contemplates a sample cylinder having a flexible isolation barrier and integrated valving to provide a controlled ingress of sample gas at nominal pressure differential. The system thereby avoids throttling of the sample gas and the inherent cooling problems associated therewith when the stream is at or below hydrocarbon dew point temperature. The flexible isolation barrier of the present invention is relatively inexpensive and is configured for quick and easy replacement, which may be routinely performed to insure sample integrity. Alternative embodiments of the invention contemplate a spherical sample cylinder configuration with flexible isolation barrier, as well as an improvement for piston-type sample cylinders to provide constant sample pressure.
