An injection-style zero-hydrocarbon emissions calorimeter is a specialized instrument used for measuring the calorific value of flare line while allowing the stream bypass to return to process, without added air and no environmental impact.

Unlike traditional flame calorimeters that require the use of a constant flow of hydrocarbon fuel for ignition and operation, an injection-style zero-hydrocarbon emissions calorimeter does not require an alternative ignition system. Uses an internal furnace at 1000C to fully combust all the sample, including Sulphur’s and eliminates the need for additional hydrocarbon fuels to operate the calorimeter.

• Industrial PLC System, touchscreen HMI
• High temperature combustion
• Flameless / no flameouts
• Built for indoor, outdoor, dirty, and corrosive environments
• Precise measurement of air fuel ratio
• Global service and repairs
• Compact, sturdy O₂ Cell is designed to be cost-effective, and for ease of maintenance and service
• Internal sample system up to 50°C with options to 100°C
• Full measurement range of the heating value without the need of a specific gravity meter

Key advantages to using our measuring principle, based on the Residual Oxygen Measurement Method, are its minimal drift with changes in ambient temperature, fast response times with the ability to process low heating value sample gases without instruments shut down. A small constant volume of sample gas is injected into a continuous flow of combustion air with each measurement cycle, providing a precisely maintained fuel/air ratio profile. The fuel air mixture is oxidized in the combustion furnace at 1000°C, and the residual oxygen concentration of the combustion sample is measured by a zirconia oxide sensor. The residual oxygen provides an accurate method of measuring Heating Value with optional measurement of Wobbe Index correlated to Specific Gravity of the sample gas.

U.S. Environmental Protection Agency (EPA) Regulations Updated

Flare Gas Monitoring Solutions

On December 2, 2023, the U.S. Environmental Protection Agency (EPA) revealed its conclusive regulation aimed at significantly slashing methane and air pollution emissions originating from oil and natural gas operations. This comprehensive final measure, spanning over 1,600 pages, encompasses enhanced and updated standards for methane and other air pollutants from new, modified, and reconstructed sources. Additionally, it provides emissions guidelines to aid states in formulating plans aimed at curbing methane emissions from existing sources.  Download the EPA Fact Sheet
