Apparatus for improving the separation of fluids of different densities

Claim 1

Apparatus for mounting in a fluid separation zone to improve the gravitational separation of fluids having different densities, said apparatus comprising: (a) fluid entry means connected to an opening into said separation zone; (b) fluid distribution means mounted upon the terminus of said fluid entry means within said separation zone; (c) said fluid distribution means including at least one aperture whereby said fluids are dispersed within said separation zone; (d) an elongated imperforate chamber which is vertically oriented, and encompasses and is in fluid communication with said fluid distribution means; (e) a slotted chamber which is coextensive and in fluid communication with an upper end of said imperforate chamber; (f) said slotted chamber having an imperforate upper end plate and having vertically oriented slots arranged about the sides of said slotted chamber and in direct communication with said fluid separation zone; and (g) packing means disposed in at least a portion of said imperforate chamber, the cross-sectional area of said slots of said slotted chamber being sufficient with respect to the available flowing cross-sectional area of the resulting packed bed of said imperforate chamber, to prevent an increase in the velocity of said fluids to improve the gravitational separation of said fluids having different densities.

Claim 15

A method for gravitationally separating fluids having different densities which method comprises the steps of: (a) passing an admixture of fluids having different densities into a separation zone; (b) distributing said fluids to provide a generally upflowing vertical stream of fluids having a reduced velocity; (c) contacting said upflowing stream of fluids with a bed of packing wherein separate fluid phases are coalesced; (d) altering the direction of flow of said separate fluid phases to a generally horizontal flow; (e) passing said separate fluid phases through slotted apertures having a combined cross-sectional area sufficient to ensure complete coalescence without increasing the velocity of said separate fluid phases; and (f) recovering said separate fluid phases.

Claim 16

A method for gravitationally separating fluids having different densities which method comprises the steps of: (a) passing an admixture of fluids having different densities into a separation zone; (b) distributing said fluids to provide a generally upflowing vertical stream of fluids having a reduced velocity; (c) contacting said upflowing stream of fluids with a bed of packing wherein separate fluid phases are coalesced; (d) altering the direction of flow of said separate fluid phases to a generally horizontal flow; (e) passing said separate fluid phases through slotted apertures having a combined cross-sectional area sufficient to ensure complete coalescence without increasing the velocity of said separate fluid phases; and (f) recovering said separate fluid phases.
