Automated methods and systems for diverting transmix from a petroleum pipeline are provided to reduce the overall production of transmix on the pipeline, based on pre-defined programmed cut-points associated with the various subtypes of hydrocarbon carried on the pipeline.

A gas purging device for removing hazardous gas from a gas line has a main body with a first end and a second end. The main body has a major exterior wall extending from a first end to a second end of the main body, and an inner surface that defines a cavity of the main body. The cavity is in fluid communication with the first opening and the second opening of the main body. An airflow conduit is disposed through the major exterior wall of the main body. The airflow conduit has a first section and a second section. The first section is disposed outside of the main body and has an air inlet. The second section is disposed in the cavity and has an air outlet. A grounding wire is in electrical communication with the major exterior wall of main body.

An apparatus for containing fluid released from a vessel during a bleeding operation to release pressure formed therein comprises an enclosed receptacle defining an interior of the receptacle for receiving the fluid discharged from the vessel due to the pressure during the bleeding operation, an inlet port fluidically communicated with the receptacle interior for fluidically coupling the interior with the vessel so that the fluid released from the vessel during the bleeding operation can be guided to the interior of the receptacle, a gas pressure release valve arranged to release to an external environment of the receptacle a gaseous portion of the fluid in the interior of the receptacle received from the vessel, and a drain port for selectively releasing a liquid portion of the fluid received from the vessel.

A flow monitoring system is described for monitoring flow of a mixed-phase sample comprising at least a first phase and a second phase having different electrical conductivities, the second phase being a liquid or a gas and substantially electrically non-conductive and the first phase being a liquid and having a conductivity higher than the second phase. The system comprises: a conduit through which the mixed-phase sample can be arranged to flow; tomography apparatus arranged to generate tomography data indicative of at least a first conductivity profile of at least a portion of a first cross section of the mixed phase sample when flowing through the conduit; a flow meter arranged to detect flow of the first phase though the conduit and provide a flow signal indicative of a flow velocity of the first phase; and processing means adapted to calculate, from said data, a fraction of said first cross section occupied by the first phase, and calculate, from said fraction and said flow signal, a volumetric flow rate of the first phase through the conduit.

The present invention describes a tubular scoop that may be utilized with various assemblies for sampling fluid in a pipeline. The scoop includes a bend with a bend radius that is from two to four times the diameter of the scoop. The scoop defines a scoop face that is parallel to an axis of the tubular of the scoop. The scoop is mounted with a threaded connection that seals around the tubular. An additional seal comprises a compression nut that allows orientation of the scoop within the pipeline whereupon the scoop orientation is fixed by tightening the compression nut. In one embodiment, the scoop is a single outer tubular with internal bi-directional flow.
