    Blog: 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 is caused by a surge in the flow of natural gas behind the plunger. This short...

    Flow Solutions Blog: It is time to get operational flow measurement uncertainty under control

    Current oil & gas market conditions are putting greater focus on enhancing profitability using existing assets. This has also intensified the tension between cost and risk. Even investments that can optimize costs, minimize losses, or mitigate operational risk are being scrutinized much more diligently today. Flow measurement is a critical component in measuring for losses and for accurate custody transfer, so there...

    Blog: Continuous Gas Analyzers for Emissions, Gas Analysis and Compliance

    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 technologies can be found in many industries...

    Blog: Gas Chromatograph Validation in Natural Gas Custody Transfer Applications

    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 Journal article, Verifying Gas Chromatographs...

    Blog: Chinese Power Plant Demonstrates Criticality of Effective Level Measurement in High Pressure/High Temperature

    by Robin Hudson, Rosemount Level Product Manager, Emerson Automation Solutions An interesting case history from a 600 kW coal fired power plant in China has implications for any safety-critical environment. This application involved drain pot alarms on super critical steam lines. As you know, any liquid entering a steam turbine will cause damage. This is costly and even more important, can be dangerous to personnel...

    Flow Solutions Blog: Achieving Improved Combustion Control for Fired Heaters is Easy, Right?

    When you can control processes in refineries and petrochemical plants, you can better control the revenue generated by those facilities. The heat from fired heaters drives those processes, generating the steam for boiler applications, helping to catalyze cracking, fractionation or distillation. It stands to reason that by controlling the heat, or energy consumption you’ll have one part of maximizing the revenue mastered...

    Flow Solutions Blog: Ensure the Reliability of Your Small Volume Liquid Prover

    One of the most important elements of a fiscal liquid hydrocarbon metering installation is proving the validity of the flowmeter. Proving validates consistent meter accuracy, meter trending, and proves traceable evidence of meter performance. That is why maintaining the prover in top working condition is key to ensuring reliable, long term measurement accuracy. There are many factors that can affect the maintenance and...

    Blog: Avoiding Hydrocarbon Leakage During Storage Tank Water Draining Operations

    Storage tanks play a pivotal role in the supply chain from upstream oil & gas production through downstream petrochemical-based products. Separation of water from the hydrocarbon liquids during storage create the need for operations to remove and treat this water as it builds up over time. Emerson’s Ryo Hashimoto shared a story of an Asian petrochemical manufacturer who had numerous naphtha and pyrolysis...

    Blog: Reducing maintenance and improving safety and reliability on supercritical steam lines

    The Mobrey Hydratect 2462 Water and Steam Detection System is the modern equivalent to float level switches and is suitable for process conditions of 4350 psi / 300 bar and 1040° F / 560°C. It is used on safety critical applications to detect the unwanted presence of water in steam, or the water level within a steam drum. A new Emerson case study details a typical application for the Mobrey Hydratect 2462. The...
