Tank gauging is the process of measuring liquids in storage tanks to determine the volume and mass of the liquid. Typically, these measurements include level, temperature and pressure. A new user guide, The Engineer’s Guide To Tank Gauging is available to request for download. This 104-page guide explores tank gauging technologies, engineering standards and approvals, […]

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 […]

Flow measurement is critical in fiscal measurement applications from custody transfer to allocations between parties. The choice of technologies is broad and dependent on the fluid being measured and properties of the application. In an Applied Automation article, Selecting flowmeters for natural gas, Emerson’s Dan Hackett describes the need for different flow measurement technologies across […]

Natural gas liquids (NGLs) are composed of many hydrocarbons including ethane, propane, butane, pentane and natural gasoline. Measuring the volume of this hydrocarbon mixture required for its sale is challenging because of the impact of pressure, temperature and how the different-sized molecules pack together. Emerson’s Dean Minehart has written a whitepaper, Natural Gas Liquid Measurement: […]
