Abstract: A crude Ar refining process involves simultaneous 02 and N2 removal by a purely cryogenic process comprising (a) liquefying and then cooling with liq. N2 in a crystalliser (2) to 5-20 K below the m.pt. of pure Ar; (b) feeding the resulting liq-solids mixt. to a fractional crystallisation column (3) in which the mixt. passes downwardly in counter-curent to a liq. mixt. derived from the crystals melted at the column bottom so that part of the upflowing liq. crystallises on the down flowing crystals, resulting in Ar enrichment on the crystals and Ar depletion in the upflowing liq. (c) withdrawing O2- and N2-free liq. Ar at the column bottom; (d) opt. passing the liq. Ar through an absorption column for removal of differently melting and boiling components such as H2O, CO2 and light hydrocarbons; and (e) withdrawing more highly O2 and N2 contaminated crude Ar, from the top of the fractional crystallisation column (3). USE/ADVANTAGE - The process is useful for refining the crude Ar from the Lachmann stage of the upper column of the double column in an air fractionation plant. It allows high purity Ar recovery from liq. or gaseous crude Ar with high variable impurity contents.
