Gas-Solid Reaction Properties of Fluorine …

We have been developing a new dry-type off-gas treatment system for recycling fluorine from perfluoro compounds present in off-gases from the semiconductor industry. The feature of this system is to adsorb the fluorine compounds in the exhaust gases from the decomposition furnace by using two types of solid adsorbents: the calcium carbonate in the upper layer adsorbs HF …

29.06.2017· Fluorine exists as a diatomic gas and its chemical formula is . Whereas calcium exists in solid state and has a chemical formula Ca. Therefore, when fluorine gas reacts with calcium metal then it results in the formation of compound calcium fluoride. The chemical reaction will exist as follows.

Calcium fluoride | Solvay

calcium ion concentrations. Fluoride poisoning is associated with hypocalcemia (low calcium levels), hyperkalemia or about the size of the palm of your hand. Concentrated HF burns can be fatal if only 2% of the body surface area is exposed. 2) Eye Contact high exposure to fluoride salts. E. Working with Hydrofluoric Acid 1)

Calcium Metal - an overview | ScienceDirect …

Heavy metals, such as nickel and vanadium, are generally low, but alkaline metals (calcium, sodium and magnesium) may be high. This is highly variable and, in addition, other contaminants such as barium and lead may be elevated. Filterable solids can be higher than conventional crude oils, with greater volume and smaller particle size.

Fluoride Reduction / HF

The removal of fluoride requires that the hydrofluoric acid (HF) be converted to calcium fluoride (CaF2) which is insoluble. Calcium fluoride is a relatively insoluble salt and therefore the low fluoride discharge limit is obtainable because calcium fluoride solubility in water is very low.

Fluoride Removal Systems

Fluoride wastewater treatment is increasingly important to the discharge authorities, and discharge limits of 20 ppm and lower are now common. Traditional fluoride treatment systems with calcium based chemistries can reduce fluoride discharge levels to below 20 ppm.

Chemical Elements - Fluorine

At contact with water, it forms the very caustic hydrofluoric acid, HF. Its salts (fluorides), especially fluorite (calcium fluoride, CaF 2), which is shown here, frequently occur in nature as minerals. Fluoride is needed for bones and teeth, but quickly becomes poisonous if the dose is too high. Fluorites gave the phenomenon fluorescence its name.
