    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.

    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.
