Direct Mass Measurement of Flare & Combustor Gas Flow Rates

Posted by TechStar on Nov 18, 2020 8:42:00 AM

Providing exceptional low-flow sensitivity for accurate measurement over a wide range of flaring operations

Flare stacks and combustors are used to burn waste gases from the plant, converting chemical and organic hydrocarbons into primarily water vapor and CO2. Some processes also use relief valves to vent flammable gases to the flare stack during upset conditions.

Applications include oil and gas well drilling operations, oil refineries, chemical process plants, gas distribution infrastructure, and landfills. Flares are subject to stringent regulations, requiring operators to measure, record and report the amount of flared gases.

Due to the potential for large changes in flow rates, density, pressure and gas composition, flare gas measurement is one of the most difficult and demanding flow applications. Fox Thermal flow meters have demonstrated their ability to measure the low-flow rates typical of normal flare conditions, and also the high velocities found in upset conditions.

Fluid composition and installation anomalies can also affect flow meter performance. Fox Thermal's calibration lab employs a wide range of gases, gas mixtures, temperatures, pressures and line sizes to simulate actual fluid and process conditions. This real-world approach improves installed accuracy and minimizes measurement uncertainty.

Thermal Mass Flow Meters for Oil and Gas Applications

Posted by TechStar on May 23, 2018 9:05:00 AM
Beyond traditional oil and gas extraction techniques, the Oil & Gas Industry has been booming in the United States and around the world since the demand for shale oil has led to horizontal fraction drilling all over the world and even in several regions of the U.S. This drilling is happening both on and offshore to tap into vast quantities of resources trapped in the porous shale deposits deep underground and under the seabed. The flow back from shale oil plays has many different components that must undergo a process of separation in order to isolate the resources for use. Once separated, the byproducts are often stored in tanks before being transported for distribution and sale.
