摘要： A multi-stage pressure regulator in which pressure is first reduced by a set ratio in one or more stages followed by an adjustable pressure output stage. The system of the present invention provides for distribution of the Joules-Thomson (JT) cooling effect between multiple stages. The present invention thereby provides a system to control pressure reduction and thus prevent condensation (and associated distortion of a vapor composition sample) of a gas due to J-T cooling effect.

摘要： 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.

摘要： A sample pump system for metering the amount of sample taken from a pressurized fluid process such as a natural gas pipeline or the like, the sample pump system designed for immersion, directly or indirectly, into the pressurized fluid stream so that the sampling is taken at the prevailing pressure and temperature of the fluid stream.

摘要： A system for the retrieval and initial conditioning of sample gas for “on line” analyzers or filling of gas sample cylinders. The preferred embodiment of the present invention contemplates a system configured to obtain a representative gas phase sample from a process gas containing entrained liquid, or a process gas which generally is highly susceptible to partial condensation of some gas phase components. The preferred embodiment of the present invention teaches an assembly including a phase separation membrane and housing configured to facilitate the removal of entrained liquid from a sample gas stream. Accuracy of the sample is enhanced, and compositional changes are avoided by first extracting a sample from the process gas followed by removal of entrained liquid it may contain, with the entrained liquid removal being conducted at the prevailing process gas pressure and temperature. Thereafter the liquid free sample may be desaturated by lowering its pressure to reduce its susceptibility to condensation.

摘要： An assembly for insertion and retraction of probe or probe-like device which does not require a seal or packing gland, instead utilizing pressure equalization between pressurized process fluids and the housing containing a probe, so as to negate the use of a dynamic seal. The preferred embodiment of the present invention contemplates an inserting/retraction mechanism for raising and lowering the probe into and from the pressurized fluid, respectively. A housing having a valve is configured to allow fluid communication between the pressurized fluid source, and the interior of the housing assembly. A conduit engages the housing assembly, and is formed to slidingly receive the outer diameter of the probe therethrough, such that a sliding seal maintains a fluid seal between the outer wall of the probe and the inner wall of the conduit, as the probe is telescoped therethrough during insertion and retraction of the probe into/from the pressurized process. Fluid flow will occur until the pressure of the housing assembly and the fluid source are equal to each other. The probe is then lowered through an opening in the first end of the housing assembly without having to overcome the force exerted by the differential pressure across a dynamic seal. An example of the insertion/retraction mechanism of the present invention utilizes a rack and pinion system.

The preferred embodiment of the present invention contemplates a system configured to obtain a representative gas phase sample from a process gas containing entrained liquid, or a process gas which generally is susceptible to partial condensation of some gas phase components. The preferred embodiment of the present invention teaches a sample probe assembly including a heat pipe configured for maintaining sample gas drawn through said sample probe at or near the source gas temperature and pressure. Accuracy of the analysis of source gas stream is enhanced and compositional changes of the gas phase are avoided by preventing the partial condensation of gas components or vaporization of entrained liquid. Alternative embodiments teach the insulation of the sampling conduit to maintain the sample gas at an isothermal condition equivalent to that of the fluid stream from which it is sampled.
