Abstract
PURPOSE: To simply and efficiently remove HF from HF-contg. HCl gas and purify the HCl gas by treating the HCl gas with one or more out of CaO, CaCO3 and Ca(OH)2.
CONSTITUTION: HF-contg. HCl gas is passed through an adsorption tower filled with powder or ganules of one or more out of CaO, CaCO3 and Ca(OH)2 at ordinary temp. and ordinary press. The space velocity depends on the concn. of the gas supplied, and when the concn. of HF is below 8mol%, the HF content of the HCl gas can be reduced to less than 5ppm (as 35% phdrochloric acid basis) by passing the gas at a space velocity of 50W300l/l.hr.
