    Hydrogen Fluoride (HF) Monitoring in Air

    Hydrogen Fluoride (HF) is a colorless gas that is used extensively in industrial applications. Fluoride monitoring is especially needed for aluminum plants that need to convert HF into fluorine for use in their processes. Any HF that escapes is a cost to the plant, so an HF analyzer is essential to keep track of and prevent the losses.

  • Measurement solution for HF emissions from brickworks

    Brick kilns, as well as other plants such as ceramics manufacturers and fertiliser producers, are a major producer of hydrogen fluoride (HF) emissions. HF is highly reactive gas and seriously damaging to human health, so has strict emissions limits imposed by legislation. In addition to the effects to humans, emissions have been found to damage crops and fruit trees, as well as the general environment. The brick industry strives to reduce the amount of HF emissions and numerous projects have been carried out into the research and development of proposed process modifications that introduce ways to reduce hydrogen fluoride emissions via the latest technology such as filters and scrubbers.

    Emissions Monitoring for Mining / Emissions Monitoring for Smelting

    The Opsis monitoring solution for mining and smelting applications is based on either DOAS or laser diode technique. Opsis non-contact monitoring solutions are very well suited for applications in the Mining and Smelting Industries, as the flue gas conditions often involves high temperatures and high dust concentrations. The on-line, open-path systems are used for monitoring HF, sulphur dioxide, SO3 and HCl in potrooms, in fence-line applications and in continuous emissions monitoring.

    Continuous emissions monitoring for aluminium smelters

    Process control and emissions monitoring in an aluminium smelter is a challenge due to the high concentrations of HF. To use an extractive system in this environment will demand a lot of maintenance.

    Continuous emissions monitoring for brick plants

    Process control and emissions monitoring in a brick plant is a challenge due to the high concentrations of HF. The HF is generated in the process and gas phase HF can reach 50 mg/m3 or more. To use an extractive system in this environment will demand a lot of maintanence.

    Fluoride emissions monitoring in aluminum smelters

    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 during the electrolytic process phase to the atmosphere. The gas emissions need to be monitored. Typically the smelters have emission limit values (ELVs) for sulfur dioxide and hydrogen fluoride emissions. These emissions should be measured accurately and with good precision, to ensure the smelter does not exceed its emission limit values. In addition several fluoride compounds may be produced in the electrolytic bath in the event of an oxygen shortage. 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 today has the potential of heating the atmosphere as much as 7,000 kilograms of carbon dioxide over the next 100 years.

  • Gas Detection Solutions for Aluminium

    Primary aluminium smelting generates large amounts of hydrogen fluoride gas (HF). Worker safety and ambient air quality concerns require that HF be monitored at several locations in smelters. Traditionally, a variety of chemical sampling methods have been used for HF monitoring in and around smelters. However, these methods are labour intensive and require ongoing maintenance and consumables. During the past decade, laser based HF analyzers have been replacing the traditional methods. Laser analyzers are compact, robust and reliable and provide accurate HF data. Fast response times that enable easy correlation of high HF emissions with work practices.
