Pollutant Information: Hydrogen Fluoride
About Hydrogen Fluoride
Category: Air pollutants
Hydrogen fluoride (HF) is an acidic gas released to air from combustion of fuels that contain trace amounts of fluoride. Some industrial processes manufacture HF and/or use it as a reagent, also giving rise to emissions. Hydrogen fluoride is chemically very similar to HCl and emissions of HF display a similar source pattern to HCl. Like HCl, power generation is the most significant source, contributing 47% of total HF emission in 2014. The reduction of the emissions from this sector with time (84% since 1990) is an indication of the increased use of emission abatement equipment in power stations and reduction in the use of coal. Emissions of HF from the residential sector have also decreased with time. This is due to the decreasing use of coal for domestic heating.
Time series graph
|Start year||End year||Sector||Information||Impact|
|1984||1985||Public Electricity and Heat Production||Miners strike resulting in a reduction in the consumption of coal and an increase in the consumption of alternative fuels in power stations for that year.||Decrease in emissions|
|2009||2012||Public Electricity and Heat Production||The economic downturn has caused significant reductions in energy demands and many industries have made cut backs or closures, resulting in reduced emissions.||Decrease in emissions|
