First Claim
Patent Images
1. An oil-water separation system comprising:
- a first coalescer, said first coalescer comprising;
a housing having an inlet for receiving an oil-water mixture and an outlet connectable to a conduit;
a stack of grooved oleophilic disks located within said housing for coalescing oil from said oil-water mixture flowing between said disks from said inlet to said outlet wherein adjacent disks are touching; and
a means for forcing said oil-water mixture to flow between said disks;
a first conduit having first and second ends, said first end being connected to said outlet; and
an oil separator, said separator comprising;
a housing having an inlet for receiving fluids, an upper outlet for removing separated oil, and a lower outlet for removing separated water, said separator inlet being connected to said second end of said first conduit;
a second conduit having first and second ends, said conduit being attached to said lower outlet at said second conduit first end; and
a second coalescing unit comprising;
a housing having an inlet for receiving fluid and an outlet, said second conduit second end being connected to said second coalescing unit inlet;
a stack of grooved oleophilic disks located within said housing for coalescing oil from said oil-water mixture flowing between said disks from said inlet to said outlet, wherein adjacent disks are touching and wherein said stacked disks define a mesh having a greater numerical value than a mesh defined by said first coalescer stacked disks and wherein said mesh defined by said second coalescing unit stacked disks is coarse enough to prevent coalesced oil from being forced downstream in reduced drop sizes; and
a means for forcing said water to flow between said disks.

Abstract
A method and materials for separating oil from water, using stacked disks to coalesce the oil, is disclosed. The method of coalescence allows configuration of systems which are compact, efficient, adaptable to modular configuration, and have a very high flow rate.

3. An oil-water separation system comprising:
-
a first coalescer, said first coalescer comprising; a housing having an inlet for receiving an oil-water mixture and an outlet; a stack of grooved oleophilic disks located within said housing for coalescing oil from said oil-water mixture flowing between said disks from said inlet to said outlet; and a means for forcing said oil-water mixture to flow between said disks; a first conduit having first and second ends, said first end being connected to said first coalescer outlet; an oil separator, said separator comprising; a housing having an inlet for receiving fluids, an upper outlet for removing separated oil, and a lower outlet for removing separated water, said separator inlet being connected to said second end of said first conduit; a second conduit having first and second ends, said second conduit being attached to said lower outlet at said second conduit first end; a second coalescing unit comprising; a housing having an inlet for receiving fluid and an outlet, said second conduit second end being connected to said second coalescing unit inlet; a stack of grooved oleophilic disks located within aid housing for coalescing oil from said oil-water mixture flowing between said disks from said inlet to said outlet, wherein adjacent disks are touching and means for forcing said water to flow between said disks; and a third conduit, said third conduit having first and second ends, said third conduit first end being connected to said second coalescing unit outlet; and a carbon adsorpter, said adsorpter comprising; a housing having an inlet for receiving fluid and an outlet, said third conduit second end being connected to said adsorpter inlet and adsorptive carbon located in said housing. - View Dependent Claims (4, 5)

6. An oil-water separation system comprising:
-
a coalescer, said coalescer comprising; a housing having first and second chambers and an inlet for receiving oil-water mixture in said first chamber and an outlet in said second chamber; a passageway from said first chamber to said second chamber having an opening in said second chamber substantially above said outlet; a stack of grooved oleophilic disks located within said housing first chamber for coalescing oil from said mixture flowing between said disks to said passageway to said second chamber; a means for forcing said mixture to flow between said disks; and a plastic mesh located in said second chamber between said passageway opening and said outlet. - View Dependent Claims (7)
