Abstract
Abstract ABSTRACT A method and apparatus for separating oil from a mixture of oil and water wherein a stream of the mixture is directed along an upwardly inclined inverted channel to separate the oil from the mixture by contact of the oil with the under-surface of the channel for flow upwardly in the channel, and wherein the oil is collected from the upper longitudinal end of the channel and wherein the remainder of the stream is allowed to fall downwardly out of the channel.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
169 words
Apparatus for separating oil from a mixture of oil and water, including an assembly comprised by a plurality of up-wardly inclined laminar flow control members of inverted channel shape from end to end arranged in side by side relation in each of a plurality of spaced vertical levels, means for introducing a stream of the mixture at the bottom of said assembly for up-ward flow therethrough for separation of the oil by contact with the under-surfaces of said members, means for discharging the oil, thus constrained, from the upper ends of said members, said members being so constructed and arranged in the apparatus, that the remainder of the mixture, after said separation of the oil, flows downwardly out of the members in the upper end region of the assembly thereof but prior to reaching the upper end thereof, while said downwardly flowing remainder of said stream from channels in upper levels is prevented from counter-flow contact with the already separated upwardly flowing oil discharged from channels in lower levels.
Claim 2
Dependent Claim
169 words
Apparatus for separating oil from a mixture of oil and water, including an assembly comprised by a plurality of up-wardly inclined laminar flow control members of inverted channel shape from end to end arranged in side by side relation in each of a plurality of spaced vertical levels, means for introducing a stream of the mixture at the bottom of said assembly for up-ward flow therethrough for separation of the oil by contact with the under-surfaces of said members, means for discharging the oil, thus constrained, from the upper ends of said members, said members being so constructed and arranged in the apparatus, that the remainder of the mixture, after said separation of the oil, flows downwardly out of the members in the upper end region of the assembly thereof but prior to reaching the upper end thereof, while said downwardly flowing remainder of said stream from channels in upper levels is prevented from counter-flow contact with the already separated upwardly flowing oil discharged from channels in lower levels.
Claim 3
Dependent Claim
32 words
Apparatus according to Claim 1 wherein said channel members in each said level are spaced laterally from one an-other and the channel members in adjacent levels are arranged in respectively staggered relationship.
Claim 4
Dependent Claim
24 words
Apparatus according to Claim 2 wherein the channel members in each level are mounted on a plurality of longitudin-ally spaced transversely extending support bars.
Claim 5
Dependent Claim
43 words
Apparatus according to Claim 1 wherein each said channel member has an L-shaped cross-section whereby its under-surfaces define a downwardly open apex, the collected oil flowing upwardly along the channel surfaces at said apex to discharge at the upper end of said member.
Claim 6
Dependent Claim
20 words
Apparatus according to Claim 4 wherein the cross-sections of the channel-shaped members are arranged to lie on a square lattice.
Claim 7
Dependent Claim
73 words
Apparatus according to Claim 1 further comprising a tank in the form of an upwardly inclined duct which opens at its upper end into a chamber, said assembly of channel-shaped members extending through said upwardly inclined duct from a position upwardly spaced from the extreme lower end thereof to terminate at a position within said chamber, there being means for introducing the mixture to be treated to the lower end of said duct.
Claim 8
Dependent Claim
31 words
Apparatus according to Claim 6 wherein an oil collecting reservoir is provided at the head of said chamber, and wherein a water outlet is provided at the base of said chamber.
Claim 9
Dependent Claim
18 words
Apparatus according to Claim 7 having a weir over which oil can flow for removal from said reservoir.
Claim 10
Dependent Claim
46 words
Apparatus according to Claim 6 wherein baffle plate means is provided extending upwardly beneath the assembly of channel-shaped members, said baffle means termin-ating at a position below the extreme upper longitudinal end of said assembly and where a major fraction of the oil has beer separated.
Claim 11
Dependent Claim
31 words
Apparatus according to Claim 1, wherein each channel in a lower level passes through and terminates beyond a vertical plane passing through the ends of the channels in the level above.
Claim 12
Independent Claim
155 words
A method for separating oil from a mixture of oil and water comprising the steps of: directing a mixture of oil and water along an upwardly inclined assembly which comprise a plurality of of upwardly inclined laminar flow control members of inverted channel shape from end to end arranged in side by side relation in each of a plurality of spaced vertical levels to separate the oil from the mixture by contact with the under-surfaces of said members and constrain the thus separated oil therebelow, discharging the oil, thus constrained, from the upper ends of said members, withdrawing the remainder of the mixture, after said separation of the oil, downwardly out of the members in the upper end region of the assembly thereof prior to reaching the upper end thereof, while preventing counterflow contact between said downwardly flowing remainder of said stream with the already separated upwardly flowing oil discharged from channels in lower levels.
Claim 13
Independent Claim
155 words
A method for separating oil from a mixture of oil and water comprising the steps of: directing a mixture of oil and water along an upwardly inclined assembly which comprise a plurality of of upwardly inclined laminar flow control members of inverted channel shape from end to end arranged in side by side relation in each of a plurality of spaced vertical levels to separate the oil from the mixture by contact with the under-surfaces of said members and constrain the thus separated oil therebelow, discharging the oil, thus constrained, from the upper ends of said members, withdrawing the remainder of the mixture, after said separation of the oil, downwardly out of the members in the upper end region of the assembly thereof prior to reaching the upper end thereof, while preventing counterflow contact between said downwardly flowing remainder of said stream with the already separated upwardly flowing oil discharged from channels in lower levels.
