摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A probe structure for inserting into and operating upon an object within a pipeline, especially a high pressure pipeline carrying liquid or gas, is characterized by two coaxial cylinders that can be either pneumatically or hydraulically actuated. A primary cylinder is adapted to be mounted onto a pipeline tee and/or valve, and includes a movable primary piston to which is fixedly attached a primary lower hollow shaft that moves with the primary piston and preferably a primary upper hollow shaft that also moves with the primary piston. The primary lower hollow shaft is adapted to selectively extend into the pipeline while the primary upper hollow shaft extends above the primary cylinder and is fixed to a secondary cylinder, such that the secondary cylinder moves with the primary piston. The secondary piston includes a secondary piston that moves independently of the first and second cylinders. A secondary hollow shaft is fixedly attached to the secondary piston and coaxially extends through the primary upper and lower hollow shaft, and a central bore in the primary piston, and is adapted to selectively extend into the pipeline. In this manner, an object attached to the primary lower hollow shaft may be inserted into the pipeline, while the secondary hollow shaft provides for a second operation to be performed on the object. Wires may extend through the secondary hollow shaft or air may be circulated therethrough for pneumatic purposes. As an alternative embodiment the automatic insertion device can comprise a removable primary cylindrical housing utilized for inserting the primary insertion tool and a secondary cylindrical housing for telescopically inserting a hollow tube.

摘要： A sample cylinder for holding natural gas or other fluid samples for analysis which can completely clear itself of one sample before being filled with a subsequent sample. The piston is adapted to receive an elastomeric head which is preferably concave to the end cap. The end cap is also preferably sloped downward toward the outlet. When the piston head contacts the end cap, contact begins near the cylinder body wall and progresses inward to the outlet. The end cap is adapted to receive an elastomeric gasket seal instead of an o-ring. No spaces are left between the end cap and the cylinder body which could retain sample fluid.
