Abstract
Abstract An apparatus for separating commingled heavier and lighter immiscible liquids and solids having an upright vessel, a vertical flow tube within the vessel having an upper fluid outlet opening and a lower fluid inlet opening therein, an upper horizontal spreader baffle extending from the flow tube and below the fluid outlet and a lower horizontal spreader baffle extending from the flow tube and above the fluid inlet, a concentric side tube positioned exteriorly of and parallel the vessel and connected to the flow tube below the fluid inlet and providing for the maintenance of a liquid/liquid interface within the vessel above the upper spreader baffle and a commingled fluid inlet pipe extending from exterior of the baffle to the flow tube, the baffle providing means for change of fluid direction from horizontal to vertical and vise versa to improve separation of the lighter from the heavier immiscible liquids and for drawing off both the lighter and the heavier liquids from the vessel.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
164 words
Apparatus for separating commingled heavier and lighter immiscible fluids and solids comprising: an upright vessel having an outer at least substantially vertical sidewall; centrally within said vessel, means of directing commingled liquid flow vertically upwardly within said vessel; means of establishing a heavier and lighter liquid/liquid interface within the upper portion of said vessel; means of diverting said vertical upward flow to radial, horizontal outward flow in the direction toward said sidewall within the upper portion of said vessel and in close proximity and below said liquid/liquid interface; means of directing fluid flow from the horizontal to vertically downward flow in flow paths adjacent said sidewall; means of directing said vertical downward fluid flow to radial, horizontally inward flow in the lower portion of said vessel and into a centrally positioned fluid outlet wherein the heavier fluid component is withdrawn comprising a generally horizontal extending spreader baffle above said centrally positioned fluid outlet; and means of withdrawing lighter liquid from above said liquid/liquid interface.
Claim 2
Dependent Claim
164 words
Apparatus for separating commingled heavier and lighter immiscible fluids and solids comprising: an upright vessel having an outer at least substantially vertical sidewall; centrally within said vessel, means of directing commingled liquid flow vertically upwardly within said vessel; means of establishing a heavier and lighter liquid/liquid interface within the upper portion of said vessel; means of diverting said vertical upward flow to radial, horizontal outward flow in the direction toward said sidewall within the upper portion of said vessel and in close proximity and below said liquid/liquid interface; means of directing fluid flow from the horizontal to vertically downward flow in flow paths adjacent said sidewall; means of directing said vertical downward fluid flow to radial, horizontally inward flow in the lower portion of said vessel and into a centrally positioned fluid outlet wherein the heavier fluid component is withdrawn comprising a generally horizontal extending spreader baffle above said centrally positioned fluid outlet; and means of withdrawing lighter liquid from above said liquid/liquid interface.
Claim 3
Dependent Claim
54 words
Apparatus for separating commingled heavier and lighter immiscible liquids and solids according to claim 1 wherein said means of directing commingled liquid vertically upwardly within said vessel includes a centrally positioned vertical flow tube within said vessel having a lower commingled fluid inlet therein and an upper commingled fluid outlet below said liquid/liquid interface.
Claim 4
Dependent Claim
47 words
Apparatus for separating commingled heavier and lighter immiscible liquids and solids according to claim 2 including; a fluid inlet pipe connected with said flow tube commingled fluid inlet and extending exteriorly of said vessel, the fluid inlet pipe providing means to direct commingled fluid into said vessel.
Claim 5
Dependent Claim
96 words
Apparatus for separating commingled heavier and lighter immiscible liquids and solids according to claim 2; wherein said centrally positioned fluid outlet comprises a flow tube fluid inlet opening in said vertical flow tube below said commingled fluid inlet; a flow tube fluid outlet below said flow tube fluid inlet opening; a fluid outlet pipe connected with said flow tube fluid outlet and extending exteriorly of said vessel providing said means wherein the heavier fluid component is withdrawn; and a partition within said vertical flow tube between said commingled fluid inlet and flow tube fluid inlet openings.
Claim 6
Dependent Claim
45 words
Apparatus for separating commingled heavier and lighter immiscible liquids and solids according to claim 1 wherein said means of diverting upward flow to radial, horizontal outward flow within the upper portion of said vessel includes a generally horizontally extending spreader baffle below said liquid/liquid interface.
Claim 7
Dependent Claim
45 words
Apparatus for separating commingled heavier and lighter immiscible liquids and solids according to claim 1 including means of maintaining a liquid/gas interface in the top portion of said vessel and including means of withdrawing gas from the interior of said vessel above the liquid/gas interface.
