Abstract
Abstract A process and apparatus for effecting exchange crystallization and component separation in a nongaseous mixture by subjecting the mixture to compressional and centrifugal forces. The apparatus employed includes a mixture confining chamber, structure for moving this chamber through a curvilinear path so that an acceleration producing force acts on the mixture tending to change its direction of movement toward a barrier wall of the chamber, a mixture conveyance system for conveying the mixture to the chamber, and discharge ducts or passageways for removing one part of the mixture from a location relatively near the barrier wall, and another part of the mixture from a location relatively remote from the barrier wall.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
33 words
A process as defined in claim 1 wherein said first and second quantities of nongaseous materials are removed from said confining chamber while said confining chamber is being moved through said curvilinear path.
Claim 2
Dependent Claim
39 words
A process as defined in claim 1 and further characterized to include the steps of agitating said mixture immediately after it enters said confining chamber: then removing said mixture out of the zone of agitation in said mixing chamber.
Claim 3
Dependent Claim
22 words
A process as defined in claim 1 wherein said confining chamber is moved in a circular path about an axis of rotation.
Claim 4
Dependent Claim
38 words
A process as defined in claim 1 wherein said mixture is continuously positioned in, and said first and second quantities are continuously removed from, said confining chamber during the movement of the confining chamber through said curvilinear path.
Claim 5
Dependent Claim
31 words
A process as defined in claim 1, wherein said mixture includes ice and a hydrocarbon having a melting point which is slightly below the melting point of ice at atmospheric pressure.
Claim 6
Dependent Claim
41 words
A process as defined in claim 1 wherein said mixture is retained in said confining chamber until substantially all of said second material is melted, and substantially all of the second material from said mixture Is located in said first quantity.
Claim 7
Dependent Claim
23 words
A process as defined in claim 1 wherein said first and second quantities are discharged from said confining chamber in two separate streams.
Claim 8
Dependent Claim
32 words
A process as defined in claim 8 wherein said mixture includes ice and a hydrocarbon having a melting point which is slightly below the melting point of the ice at atmospheric pressure.
Claim 9
Dependent Claim
42 words
A process as defined in claim 8 wherein said process is further characterized to include the steps of agitating said mixture immediately after it enters said confining chamber; then moving said mixture out of the zone of agitation in said confining chamber.
Claim 10
Dependent Claim
42 words
A process as defined in claim 10 wherein said mixture is retained in said confining chamber until substantially all of said solid second material is melted, and substantially all of said second material from said mixture is located in said first quantity.
Claim 11
Dependent Claim
30 words
A process as defined in claim 11 wherein said first and second quantities are removed from said confining chamber while said confining chamber is being moved through said curvilinear path.
