With the diversification of crude oil types brought about by U.S. shale production, refineries have increased risk for vessel and piping corrosion. Many of the aging refineries also are operating past the design life of some of their plant assets. In a Chemical Processing article, Refineries: Rethink Corrosion Monitoring, Emerson’s Jake Davies describes some of […]

Avoiding Missed Gas Volume Flow Measurements in Plunger Lift Wells

Measuring flow rates on producing gas wells can be difficult on plunger lift applications. The mechanical plungers are used to remove water slugs which build up and reduce production rates. When the plunger pulls up the well bore, the differential pressure (DP) flow measurement can spike beyond the range of the DP transmitter. This spike […]

The combustion process leads to emissions which must be measured and reported to regulatory authorities in jurisdictions where process manufacturers and producers operate. Technologies such as Quantum Cascade Laser (QCL) and Tunable Diode Laser (TDL) are used to sense and analyze industrial gases and monitor emissions. Continuous gas analyzers that use the combination of these […]

Gas chromatographs (GCs) are used in natural gas custody transfer applications. They provide information on the gas quality and composition—with components such as methane, ethane and heavier hydrocarbons, water vapor, carbon dioxide, nitrogen and hydrogen sulfide. These gas chromatograph are normally located on large gas stations with dedicated buyer use. In a Pipeline & Gas […]

Onshore oil & gas well pads have long used small lease tanks to hold the crude oil before transferring to be hauled away, typically by crude hauling trucks. Traditionally, this custody transfer process has involved operators climbing up the lease tanks, opening the thief hatch and using a measurement stick to manually gauge the level […]
