    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...

    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...

    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...

    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...

    Solve Ammonia Slip with DeNOx Optimization Solution

    by Amanda Gogates, Cascade Global Product Manager, Emerson Nitrogen oxides are powerful pollutants that can cause smog and acid rain and contribute to the development of tropospheric ozone. It’s critical to control nitrogen oxide (NOx) emission...

    Simplifying Continuous Gas Chromatograph Online Analysis Installation

    Gas chromatographs (GCs) are used in natural gas applications to measure the hydrocarbon components. The heavier natural gas liquids beyond butane and pentane are referred to as C6+ hydrocarbons. Gas chromatographs performing C6+ analysis are used by hydrocarbon processing facilities when high-quality product specifications are required or when rigid custody transfer standards are needed in natural gas trading operations...

    Hanwha Total Petrochemicals Reduces Costs and Improves Environmental Compliance with Conductivity

    by Lee Ju Yong, Applications and Customer Service, Emerson Most of us know that conductivity is an excellent way to detect the interface between a non-conductive liquid, such as a hydrocarbon, and a conductive aqueous solution. Even more impressive, however, is hearing how this vital analysis is saving time and money for real companies. Here’s a great example. Hanwha Total Petrochemicals is headquartered in Seoul...

    Improving Burner Control with Gas Chromatographs

    There once was a time for industrial manufacturers when they received fairly homogeneous supplies of natural gas that did not vary much in energy content. Here in the U.S. with the rapid increase in shale gas production as part of the overall energy mix, there is more variance. In a Power magazine article, Gas Chromatographs Offer New Technology for Power Plant Burner Control , Emerson’s Bonnie Crossland describes...

    Calibrating Toroidal Conductivity Sensors

    By Dave Joseph, Emerson Conductivity measurement is one of the most ubiquitous in industry so the issue of how to correctly calibrate a toroidal conductivity sensor comes up for a lot of plant personnel. Because the purpose of the measurement is to get information about the total concentration of ions in solution (i.e., the conductivity), the effect of sensor dimensions and windings must be accounted for. The correction...
