Abstract
Hydrogen fluoride is removed from gases by introducing the gases into a fluidized-bed reactor to form a gas-solid suspension, entraining a major part of the solids in an upward direction separating the solids entrained by the gases without prior removal of the solids from the gas-solid suspension, by means of an electrostatic precipitator.
