  • A CFD study of the effect of venturi geometry on high pressure wet gas metering

    Venturi meter is increasingly being preferred as wet gas flow meter because of its simple construction and ease of operation. It has been found that the performance of venturi in single phase gas is very different from that of water. In this work, with a view to optimise the design, the effects of diameter, diameter ratio and convergent angle on the performance of a venturi meter for wet gas ...

  • Tech Note: Flare Gas Measurement Innovation; Retain Flow Metering Accuracy Even if Gas Composition Changes

    It’s a fact oil wells almost always produce natural gas along with the petroleum. Nine times out of ten, the excess gas (typically hydrocarbons) is flared off or simply vented as-is during upset conditions in the process. The environmental impacts of “flaring” this excess gas into our atmosphere has resulted in government regulations like 40 CFR Part 60 Subpart OOOO (also ...

  • Smartest smart meter: The gasoline pump?

    Americans do many things well. These things do not include sacrifice of creature comforts. So it came as a surprise to see US Rep. Brian Baird (D-Wash) suggest we can avert 20% of our energy use if we take short “military showers” over 20 weeks.  Who the heck is going to do that? We already know from Jimmy Carter-era energy policies that lecturing Americans does not result in sustained ...

  • Sub-metering of natural gas-flexible flow measurement delivers improved accuracy and substantial savings

    Introduction Unlike oil, natural gas exists in abundance in the United States. Of the natural gas consumed in the United States in 2011,95% was produced domestically. The U.S. Energy Information Administration projects U.S. natural gas production to increase from 23.0 trillion cubic feet in 2011 to 33.1 trillion cubic feet in 2040, a 44% increase. Almost all of this increase in ...

  • New Developments in Thermal Dispersion Mass Flow Meters: In-The-Field Compensation for Changes in Natural Gas Composition

    Introduction The flow of natural gas in pipelines is often complicated by changes in the composition of the gas. The method described in this paper solves the problem of variable composition via a new four-temperature mass flow sensor. The new (low sensor feeds its measurements into the algorithms of an advanced mathematical model that includes gas properties in its calculations. The method ...

  • Smart meters: Truly a cure for energy blindness?

    And now for a dose of reality.   No doubt smart meters are a good thing, but even their most ardent fans must admit that a degree of hoopla surrounds these little digital boxes. We hear that if consumers can just see how much power they use in real time, and what it costs, our energy woes will be no more.   Smart meters will even cure the blind. The energy blind that ...

  • Gas Import Terminal

    B&V Energy is the consortium leader for North America's first Pacific coast terminal accepting LNG from suppliers and converting and piping it at a savings to U.S. and Mexican companies. Only a 90-minute drive south from San Diego, the warm climate and sunny beaches of Ensenada, Mexico, are a popular draw for tourists. In 2008, the beaches of Ensenada will become home to another crucial ...

  • Expert assessment: Sea-level rise could exceed one meter in this century

    Sea-level rise in this century is likely to be 70-120 centimeters by 2100 if greenhouse-gas emissions are not mitigated, a broad assessment of the most active scientific publishers on that topic has revealed. The 90 experts participating in the survey anticipate a median sea-level rise of 200-300 centimeters by the year 2300 for a scenario with unmitigated emissions. In contrast, for a scenario ...

  • Sizing and Selecting the Proper Metering Pump: Part 1 of 2

    A typical agriculture or process application can consume large amounts of chemicals during daily operations. While the volumes may be large, though, they must also be very precise, with exact amounts delivered according to strict injection schedules. The pressures—from very high to very low—that the chemicals are injected at must also be governed precisely. This demand for ...
