MIXING GASES WITH LIQUIDS EUGENE W. BLANK Colgate-Palmolive-Peet Co., Jersey City, New Jersey
EFFICIENT dispersion of a gas in a liquid is readily accomplished by introducing the gas through a hollow stirrer. The agitation of the stirrer insures a large contact of the two phases and rapid absorption of the gas is a result. The accompanying figure shows an adaptation of a familiar set-up to such work. The gas is introduced into the inner chamber of a mercury seal from which it passes into the
stirrer by means of two or three holes in the wall of the hollow stirrer rod. So long as no solid product is formed as a result of the reaction between the gas and liquid this arrangement of apparatus gives very good results. Accidental clogging of the outlets of the stirrer results in the mercury of the mercury seal acting as a relief valve.
