Gas analyzers and monitoring systems for aluminum production sector - Metal - Aluminium
Production of aluminum from its ores at aluminum smelters results in carbon dioxide CO2, carbon monoxide CO, sulfur dioxide SO2, and hydrogen fluoride HF gas emissions to the atmosphere. Read about our solutions for aluminum industry!
Typically, aluminum smelters have emission limit values (ELVs) for sulfur dioxide SO2 and hydrogen fluoride HF emissions. These emissions should be measured accurately, to ensure the smelter does not exceed its emission limit values.
In addition, several fluoride compounds may be produced during the aluminum production process. These compounds include carbon tetrafluoride CF4, hexafluoroethane C2F6, sulfur hexafluoride SF6, and silicon tetrafluoride SiF4. These additional emission components are problematic, as they have high Global Warming Potential (GWP) values.
The GWP is a relative measure designed to demonstrate how much heat a greenhouse gas (GHG) traps in the atmosphere. Emission of one kilogram of carbon tetrafluoride into the atmosphere has the potential of heating the atmosphere as much as 7,000 kilograms of carbon dioxide over the next 100 years.
Production of aluminum results in a large variety of gases that need to be measured.
Gasmet manufactures portable FTIR gas analyzers and stationary FTIR emissions monitoring systems. An FTIR analyzer works by simultaneously scanning entire infrared spectrum. Our Calcmet software then calculates the concentrations of each gas in the sample based on the characteristic absorption. All the gases in the sample can be measured simultaneously because the entire infrared spectrum is scanned at once. This allows for very quick multicomponent measurements and for compensation for any cross-interference.
The Continuous Emissions Monitoring System CEMS II e offers TÜV and MCERTS certified solution (QAL1) for a wide range of demanding emission monitoring applications. The CEMS II e system utilizes Fourier Transform Infrared Spectroscopy FTIR technology.
The Gasmet DX4000 can be used when you need a portable gas analyzer solution instead of continuous gas monitoring. It is portable FTIR gas analyzer for applications where multiple gas compounds need to be accurately monitored in hot & humid sample gas. Gasmet DX4000 is the world’s smallest FTIR emissions monitoring system.
