Abstract
Abstract An apparatus for use in augmenting the separation of oil and water flowing comingled in a stream having a conduit through which the stream of comingled water and oil passes, an assembly of nodules formed of catalytic metal alloy, the nodules being generally cylindrical and having longitudinal notches on the external cylindrical surfaces and the nodules being arranged in subassemblies, each subassembly being formed of three nodules affixed to each other in a layer such that a longitudinal notch of each nodule mates with a longitudinal notch of the other two nodules to provide a central opening through the subassembly, and a central axial shaft received within the central opening retaining a plurality of the subassemblies. The complete assembly is positioned within the conduit so as to be engaged by the water and oil flowing therethrough. Each nodules being formed of an alloy of copper, zinc, nickel, lead and tin which augments the separation of the oil and water.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
225 words
An apparatus for use in augmenting separation of oil and water flowing comingled in a stream comprising: a conduit through which the stream of comingled water and oil passes; an assembly of nodules each formed of a catalytic metal alloy composition consisting essentially of a mixture of the metals: copper, zinc, nickel, lead and tin, each nodule being of generally cylindrical shape and having spaced apart paralleled longitudinal notches on the external cylindrical surface, the notches being in planes of the nodule cylindrical axis, and each nodule having an axial opening therethrough coincident with the cylindrical axis, the nodules being arranged into subassemblies, each subassembly being formed of three nodules affixed to each other in a layer and arranged such that a said longitudinal notch of each module mates with a said longitudinal notch of the other nodules to provide a central opening through the subassembly, the outside diameter of each subassembly being less than the internal diameter of said conduit; an elongated central shaft having a first end and a second end, the shaft receiving said central openings of a plurality of said subassemblies, wherein said subassemblies are arranged in layers on said central shaft to form an assembly; and means at said first and second ends of said central shaft to retain said subassemblies thereon, the retained subassemblies being positioned within said conduit.
Claim 2
Independent Claim
225 words
An apparatus for use in augmenting separation of oil and water flowing comingled in a stream comprising: a conduit through which the stream of comingled water and oil passes; an assembly of nodules each formed of a catalytic metal alloy composition consisting essentially of a mixture of the metals: copper, zinc, nickel, lead and tin, each nodule being of generally cylindrical shape and having spaced apart paralleled longitudinal notches on the external cylindrical surface, the notches being in planes of the nodule cylindrical axis, and each nodule having an axial opening therethrough coincident with the cylindrical axis, the nodules being arranged into subassemblies, each subassembly being formed of three nodules affixed to each other in a layer and arranged such that a said longitudinal notch of each module mates with a said longitudinal notch of the other nodules to provide a central opening through the subassembly, the outside diameter of each subassembly being less than the internal diameter of said conduit; an elongated central shaft having a first end and a second end, the shaft receiving said central openings of a plurality of said subassemblies, wherein said subassemblies are arranged in layers on said central shaft to form an assembly; and means at said first and second ends of said central shaft to retain said subassemblies thereon, the retained subassemblies being positioned within said conduit.
Claim 3
Dependent Claim
27 words
An apparatus according to claim 1 wherein said nodules are affixed in subassemblies by welding each of the three nodules in each subassembly to the adjacent nodules.
Claim 4
Dependent Claim
24 words
An apparatus according to claim 1 wherein each subassembly is positioned on said elongated shaft 60° out of register with the next adjacent subassembly.
Claim 5
Dependent Claim
52 words
An apparatus according to claim 1 wherein said metals are in the following percentages by weight: copper about 40 to 60 per cent; zinc about 1 to 10 per cent; nickel about 5 to 25 per cent; lead about 2 to 15 per cent and tin about 1 to 10 per cent.
Claim 6
Dependent Claim
31 words
The apparatus according to claim 4 wherein the composition of each of said nodules includes at least one trace element selected from the group consisting of: iron, antimony, sulfur and manganese.
