  • Patent number: 8347694
    Abstract: An LNG sampling system is provided which includes a sampling probe. The sampling probe includes a backflow prevention check valve positioned within the probe adjacent the inlet end. The probe is inserted into a source of LNG to extract samples of LNG by providing a pressure differential between the probe piping system and the pressure of the LNG within the source. In the event the pressure in the piping system increases above a predetermined amount, the check valve will close preventing backflow of LNG from the sampling system back into the source.

  • Patent number: 8210058
    Abstract: A sampling cylinder for LNG (liquefied natural gas) is provided. The sampling cylinder includes a piston cylinder arrangement having opposite end members closing the chamber inside the cylinder. Various porting arrangements are provided for allowing fluid to be fed into a chamber inside the cylinder on opposite sides of a piston. A sample chamber is provided at one end member of the cylinder. The end member containing the sample chamber is also provided with a heat exchanger that may be connected to a source of coolant and preferably the LNG to be sampled to effect cooling of the end member at least partially prior to the sample chamber having a sample of LNG injected thereinto.

  • Patent number: 8127625
    Abstract: A liquid separator with at least one flow passageway is used to detect and remove the presence of entrained liquids from natural gas during spot sampling procedures prior to analysis of the sample by a gas chromatograph. In one embodiment, the at least one flow passageway directs at least a portion of the gas flow to impinge upon the inside surface of a sight glass and swirl around in a chamber which may cause droplets of liquid to coalesce on the inside of the sight glass and may cause a fog to form inside the chamber, all of which make it easier to see the existence of liquids in the natural gas. The at least one flow passageway is less expensive to fabricate than some prior art flow directing elements.

  • Patent number: 8113070
    Abstract: A sight glass with a flow directing assembly is used to detect the presence of entrained liquids in natural gas during spot sampling procedures. The flow directing assembly directs at least a portion of the gas flow to impinge upon a first transparent window and swirl around in a chamber of the sight glass which may cause droplets of liquid to form on the inside of the window and may cause a fog to form inside the chamber, all of which make it easier to see the existence of liquids in the natural gas. At least one embodiment of this sight glass also acts as a fluid separator, collecting the liquids in the chamber which may then be periodically drained.

  • Patent number: 7856997
    Abstract: A removable automatic insertion device with segmented drainage shaft may be used to remove unwanted liquids from pipelines, tanks and other pressurized vessels. The insertion device inserts and withdraws the drainage shaft, one segment at a time into the pipeline or other pressurized vessel. A termination assembly is connected to the subsurface end of the drainage shaft and includes a normally closed drainage valve assembly. After insertion of the drainage shaft, the automatic insertion device is removed and a surface mounted discharge assembly is connected to the drainage shaft. To open the drainage valve assembly and commence drainage of unwanted liquids, pressurized fluid is injected through the discharge assembly, and a segmented hollow actuation tube to open the subsurface drainage valve assembly. Unwanted fluids then pass through the open drainage valve assembly, the drainage shaft to the surface mounted discharge assembly.

  • Patent number: 7194920
    Abstract: A sensor and carrier device are provided in combination with a pipeline for either placing a sensor element within the flow stream of the pipeline or a device to divert flow outside of the pipeline to measure a parameter of the conditions within the pipeline or of the gas flowing through the pipeline. The configuration of the probe comprising the carrier and sensor is such as to reduce the possibility of structural failure of the probe.

  • Patent number: 7156123
    Abstract: When sample collection cylinders get full, they need to be switched out with empty sample collection cylinders. The connection between the sample cylinder and a piping system is often a quick-connect which typically has a high pressure rating when closed and a lower pressure rating when opened. The bleeder valve of the present invention, when installed in the piping system between the quick-connect and the sample cylinder can be used to reduce the pressure in the system and the quick-connect to rated pressures before the quick-connect is opened. In an alternative embodiment intended for service with hazardous materials, the bleeder valve and seals are formed from resistant materials and the vent is connected to a flare or other suitable point of disposal.
