9800CXi Calorimeter

Injection-Style Zero Hydrocarbon Emissions Calorimeter

Injection-Style Measurement Calorimeter

Zero Hydrocarbon Emissions

Our NEW COSA XENTAUR™ 9800CXi™ Calorimeter is a fast response, injection-style zero-hydrocarbon emissions calorimeter.  It can provide direct measurement of Calorific Heating Value and BTU with a measurement range 0-3000 BTU/scfh.  A real advantage with the 9800CXi calorimeter is that it can handle high sulfur concentrations with an H2 measurement option.

An injection-style zero-hydrocarbon emissions calorimeter is a specialized instrument used for measuring the calorific value of fuels and other combustible materials without emitting any hydrocarbons into the environment. It works by injecting a small sample of the material into a combustion chamber where it is burned, and measuring the heat produced by the combustion reaction.

Unlike traditional calorimeters that require the use of a constant flow of hydrocarbon fuel for ignition and operation, an injection-style zero-hydrocarbon emissions calorimeter uses an alternative ignition system that doesn’t produce hydrocarbon emissions. This allows for a more environmentally friendly testing process and eliminates the need for additional hydrocarbon fuels to operate the calorimeter.

ADVANTAGES

Key advantages to using our measuring principle, based on the Residual Oxygen Measurement Method, are its insensitivity to changes in ambient temperature, very fast response times with the ability to measure BTU values down to zero.  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. Higher temperature reduces maintenance of the instrument; varying temperature up to 1000°C.

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
