Abstract

Abstract In the separation of a gaseous or vaporous mixture into components having respectively different molecular weights and/or gas kinetic cross sections, where a first separation is achieved by passing the mixture through a first nozzle type opening and around a first skimmer diaphragm, further separations are achieved by deflecting at least one of the partial streams passing the first skimmer and subjecting the deflected partial stream to the action of a second skimmer diaphragm which divides that partial stream into further partial streams.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 110 words
IN A METHOD FOR SEPARATING A GASEOUS OR VAPOROUS MIXTURE INTO COMPONENTS HAVING RESPECTIVELY DIFFERENT MOLECULAR WEIGHTS AND/OR GAS KINETIC CROSS SECTIONS BY CAUSING THE MIXTURE TO FLOW THROUGH A NOZZLE-TYPE OPENING WHERE IT FORMS AN EXPANDED STREAM AND BY DIVIDING THE STREAM INTO PARTIAL STREAMS BY A SKIMMER DIAPHRAGM DISPOSED IN THE FLOW PATH, THE PARTIAL STREAMS HAVING RESPECTIVELY DIFFERENT COMPOSITIONS, THE IMPROVEMENT COMPRISING: DEFLECTING AT LEAST ONE OF THE PARTIAL STREAMS IMMEDIATELY BEYOND SUCH SKIMMER, UTILIZING THE KINETIC ENERGY CONTAINED IN THAT STREAM; AND SUBJECTING SUCH DEFLECTED STREAM TO THE ACTION OF A FURTHER SKIMMER DIAPHRAGM TO DIVIDE THAT STREAM INTO FURTHER PARTIAL STREAMS HAVING RESPECTIVELY DIFFERENT COMPOSITIONS.
Claim 2
Dependent Claim 110 words
IN A METHOD FOR SEPARATING A GASEOUS OR VAPOROUS MIXTURE INTO COMPONENTS HAVING RESPECTIVELY DIFFERENT MOLECULAR WEIGHTS AND/OR GAS KINETIC CROSS SECTIONS BY CAUSING THE MIXTURE TO FLOW THROUGH A NOZZLE-TYPE OPENING WHERE IT FORMS AN EXPANDED STREAM AND BY DIVIDING THE STREAM INTO PARTIAL STREAMS BY A SKIMMER DIAPHRAGM DISPOSED IN THE FLOW PATH, THE PARTIAL STREAMS HAVING RESPECTIVELY DIFFERENT COMPOSITIONS, THE IMPROVEMENT COMPRISING: DEFLECTING AT LEAST ONE OF THE PARTIAL STREAMS IMMEDIATELY BEYOND SUCH SKIMMER, UTILIZING THE KINETIC ENERGY CONTAINED IN THAT STREAM; AND SUBJECTING SUCH DEFLECTED STREAM TO THE ACTION OF A FURTHER SKIMMER DIAPHRAGM TO DIVIDE THAT STREAM INTO FURTHER PARTIAL STREAMS HAVING RESPECTIVELY DIFFERENT COMPOSITIONS.
Claim 3
Dependent Claim 17 words
A method as defined in claim 1 comprising initially mixing the mixture with a light additional gas.
Claim 4
Dependent Claim 32 words
A method as defined in claim 1 further comprising permitting at least one of said partial streams to undergo expansion, and thus accelerate, immediately after the division which formed that partial stream.
Claim 5
Dependent Claim 37 words
A method as defined in claim 3 further comprising combining in a cascade those of the outwardly directed partial streams which have essentially the same composition regarding the components of the mixture which is to be separated.
Claim 6
Independent Claim 124 words
A apparatus for separating a gaseous or vaporous mixture into components having respectively different molecular weights and/or gas kinetic cross sections, which apparatus includes a nozzle separator composed of a first nozzle-type opening through which the mixture initially flows and a first skimmer diaphragm disposed at the outlet end of such opening and located for dividing the mixture flowing through such opening into two partial streams, the improvement comprising: means formed as an extension of said first skimmer, and located downstream thereof, defining a deflecting wall for deflecting one of the partial streams formed by said first skimmer, and a second skimmer diaphragm disposed at the downstream end of said wall for dividing the partial stream deflected by said wall into further partial streams.
Claim 7
Independent Claim 124 words
A apparatus for separating a gaseous or vaporous mixture into components having respectively different molecular weights and/or gas kinetic cross sections, which apparatus includes a nozzle separator composed of a first nozzle-type opening through which the mixture initially flows and a first skimmer diaphragm disposed at the outlet end of such opening and located for dividing the mixture flowing through such opening into two partial streams, the improvement comprising: means formed as an extension of said first skimmer, and located downstream thereof, defining a deflecting wall for deflecting one of the partial streams formed by said first skimmer, and a second skimmer diaphragm disposed at the downstream end of said wall for dividing the partial stream deflected by said wall into further partial streams.
Claim 8
Dependent Claim 61 words
Apparatus as defined in claim 5 wherein said nozzle separator comprises members forming said nozzle-type opening and said first cup-shaped skimmer, and additionally shaped to form an initial deflecting wall, an inlet channel forming the inlet end of said separator, and two extraction channels located at respectively opposite sides of said first skimmer and defining the outlet end of said separator.
