US Patent:

53043553, Apr 19, 1994

Filed:

Sep 8, 1992

Appl. No.:

7/941805

Inventors:

Robert E. Yant - Medina OH
Richard J. Galluch - Hudson OH
Mark E. Piechuta - Alliance OH

Assignee:

Quantum Technologies Inc. - Twinsburg OH

International Classification:

B01F 500

US Classification:

422225

Abstract:

A compact, heavy duty mixer-reactor is described which features a double-stage mixing/reaction chamber, one stage being of wall-baffled design and the other being unbaffled. Said mixer-reactor operates with a unique, two-stage impeller having a different set of coextensive agitator blades within each of said stages. For example, the effective radii of the blades in said unbaffled stage are significantly larger than those of the blades in said baffled stage. In addition, other differences in shape and pitch of the respective sets of agitator blades are provided to give enhanced performance, particularly in mixing and reacting finely divided solids with gases. The subject apparatus delivers outstanding results in terms of expediting thorough mixing and promoting complete reactions between fine solids and gaseous reagents. These results are particularly noteworthy when treating non-Newtonian suspensions of solids and liquids (e. g. wet wood pulps and the like) with virtually insoluble gaseous reagents such as ozone, oxygen or mixtures thereof, which often require superatmospheric conditions in order to achieve satisfactory treatment.

International Classification:

C01B 1104

US Classification:

423473

Abstract:

A process and apparatus for the manufacture of chloride-free hypochlorous acid using hydrolyzing of chlorine with steam and water vapor, solid-gas stripping of the co-generated hydrochloric acid vapor in a fluidized bed reactor, equilibrium discharge of chloride particulate from the bed of the reactor, selective dissolving of the hypochlorous acid vapor into aqueous product solution in a packed bed absorber, and closed-loop recycling of the stripped product stream.
