 |
Anhydrous hydrofluoric acid (AHF) is used to produce environmentally safer fluorocarbon products, fluoropolymers, and chemical derivatives.
It is also used in refinery alkylation as well as in a variety of other processes. Honeywell, as a global leader in the production and use of fluorine derivatives, is well positioned to supply your needs for AHF.
As the world's leading producer and consumer of AHF, we are uniquely qualified to support your efforts to receive, store and use this material. Our extensive experience with both material and equipment design can be leveraged to help our customers improve safety, efficiency, and reliability. Honeywell delivers anhydrous hydrogen fluoride via railcar and tank truck. We operate the largest specialized railcar fleet dedicated to AHF transportation in the world. Our custom-designed trucks and trailers are equipped with satellite tracking systems which allow us to pinpoint their location at any time of day or night and maintain constant communication with our driver teams. Honeywell's extensively trained driver teams, consist of a two-person crew of Honeywell employees. Two person teams are utilized regardless of the distance to a customer location.
Anhydrous hydrofluoric acid (Hydrogen Fluoride or AHF) is a clear, colorless, corrosive fuming liquid with an extremely acrid odor. Forms dense white vapor clouds if released. Both liquid and vapor can cause severe burns to all parts of the body. Specialized medical treatment is required for all exposures.
