Oil wells almost always produce natural gas (“associated gas”) along with the petroleum. In many cases, it is uneconomical to process due to heavy contamination. As a consequence, this gas is combusted, “flared” or simply vented as-is during upset conditions in the process. Newly updated EPA regulations like 40 CFR Part 60 Subpart OOOO (also known as Quad O) as well as the new RSR MACT rule for refineries, requires oil & gas companies to report the flare gas emitted to our atmosphere....

Secondary Air Flow Overview: The need for accurate, repeatable & reliable combustion air measurements in power generation plants is critical to efficient operation and safety throughout the entire facility and processes. Accurate secondary air flow measurement to the burners is critical for maintaining the proper air to fuel ratio, resulting in more complete and stable combustion, better performance and lower emissions. Coal-fired power plant applications pose a number of challenges to obtaining these...
Thermal mass flowmeters are ideal for Carbon Dioxide metering and mass flow control. Sierra specializes in accurate mass flow measurement and/or control of CO2 gas. Applications range from general industrial process control across numerous industries to Green House Gas monitoring requirements and general research.
Sierra’s offers a complete line of precision flow solutions for any gas, liquid or steam measurement to improve energy efficiency in all facilities management applications. Our mass vortex meters are used to allocate steam, our in line thermal mass flow meters track and allocate natural gas and compressed air usage, and our clamp-on and insertion ultrasonic meters provide accurate water and water-based fluid measurement.
With its high turndown and direct mass flow, our immersible thermal meters are the instrument of choice for measuring aeration basin air flow and monitoring digester gas. Our multivariable vortex meters are used to measure steam in the cogeneration processes, while our ultrasonic flowmetersare used for influent and effluent measurement.
Many large combustion plants are now required to monitor mass emissions of major pollutants and to do so requires an accurate measurement of stack gas velocity. The VCEM 5100 is certified to EN 15267 part 3 QAL 1 for all industrial processes including waste incineration. It has several key advantages, firstly the sensors optics are not in contact with the hot and dusty environment, the VCEM 5100 can monitor gases at temperatures exceeding 10000C and the analyser requires minimal maintenance. The VCEM 5100 can be...
A safe laboratory environment requires an
effective method for clearing toxic material from fume hoods. Since all handling of toxic
materials is completed in these hoods, it is
critical to have a procedure to evaluate their
operation to assure adequate protection for
laboratory workers. The InfraRan Specific
Vapor Analyzer, factory calibrated for SF6, is an ideal instrument for measuring fume hood
efficiency in accordance with ASHRAE and
other standards. Manufacturers identify the flow
dynamics (factors that...
Our thermal flow meters are widely used in flotation cells in mining. Our multivariable mass vortex flow meters are used in the oil and gas industry both at the wellhead and in the refinery. Thermal mass flow meters also have a place in the power generation industry where they are used to measure and control fuel-to-fuel air ratios.
The Tekran 2537 has been used in numerous published studies to measure the deposition or evasion of mercury from natural or contaminated surfaces (i.e. flux measurements). It is anticipated that many mercury flux measurements will be needed in the future to assess the impact of climate change on mercury cycling in the environment. There are two basic ways to do mercury flux measurements. First, the dynamic flux chamber method utilizes a custom enclosure, with controlled air flow, to measure the inlet and outlet...
The Kurz Insertion Mass Flow Meter products provide extremely reliable and accurate measurements for the harsh environment of a recovery boiler facility, without restricting airﬂow even in short run ducts.
With over 15 years of experience in the measurement of volatile organic compounds (VOC), Environment SA announces the VOC72M, a new generation analyzer for the measurement of BTEX compounds by gas chromatography with photo-ionization detector (PID). The VOC72M can handle up to 40 compounds and eight configurations for analysis. This compact and fully automated analyzer with wide voltage range specifications (90-240V) provides equivalent performance to the laboratory chromatographs and is particularly suited to...
The consumption of scrubbing material in a scrubber is related to the mass flow of acid gases. Hydrogen chloride (HCl) and sulphur dioxide (SO2) are the major acid gases in an incinerator. By measuring the mass flow of SO2 and HCl in the raw gas going into the scrubber, it is possible to calculate the required quantity of scrubbing material.
The medical industry requires the accurate and consistent performance of its equipment. IST’s precise and reliable sensors meet the needs of these applications. Flow is perhaps the most widely used sensor in this industry, controlling medical devices where a gas or fluid is being supplied to a patient, or in cases of patient monitoring. Humidity sensors also have an application in the medical industry in products that control the air present or supplied to the patient.
A variety of medical devices, such as ventilators, breath analysis equipment and anesthesia delivery monitors require a quick and precise measurement of gas flow.
