Abstract
Abstract A component of at least one of two immiscible liquids is transferred into the other liquid by introducing one of the liquids (the "first liquid") onto the surface of fibers extending generally linearly along a conduit with the fibers filling the cross-sectional area of at least a portion of the length of the conduit and being wetted preferentially by the first liquid, flowing the other liquid (the "second liquid") through the conduit past the fibers thereby dragging a film of the first liquid along the fibers, collecting the liquids in a gravity separator approximate the downstream end of the fibers and then separately removing the two liquids from the separator.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
144 words
Apparatus for effecting contact between a first first and a second immiscible liquid flowed concurrently therethrough in order to enable mass transfer therebetween, comprising: a first conduit having an inlet and outlet, said conduit inlet being adapted to receive said second liquid and said outlet being adapted for connection with a gravity separator; a second conduit of smaller diameter projecting into said inlet end of said primary conduit; nozzle means for introducing said first liquid connected to the downstream end of said secondary conduit; and a plurality of elongated fibers extending generally linearly along and filling the cross-sectional area of said first conduit's length downstream of said nozzle means, said fibers having an upstream end secured to said nozzle means and a downstream end extending beyond the end of said first conduit for immersion into separated first liquid fluid layer in said gravity separator.
Claim 2
Dependent Claim
144 words
Apparatus for effecting contact between a first first and a second immiscible liquid flowed concurrently therethrough in order to enable mass transfer therebetween, comprising: a first conduit having an inlet and outlet, said conduit inlet being adapted to receive said second liquid and said outlet being adapted for connection with a gravity separator; a second conduit of smaller diameter projecting into said inlet end of said primary conduit; nozzle means for introducing said first liquid connected to the downstream end of said secondary conduit; and a plurality of elongated fibers extending generally linearly along and filling the cross-sectional area of said first conduit's length downstream of said nozzle means, said fibers having an upstream end secured to said nozzle means and a downstream end extending beyond the end of said first conduit for immersion into separated first liquid fluid layer in said gravity separator.
Claim 3
Dependent Claim
29 words
The structure set forth in claim 1, wherein said nozzle means for introducing said first liquid comprises a nozzle having a plurality of openings in the discharge end thereof.

Claim 5
Dependent Claim
161 words
Apparatus for effecting contact between a first liquid and second immiscible liquid flowed concurrently therethrough in order to enable mass transfer therebetween, comprising: a first conduit having an inlet end outlet, said conduit inlet being adapted to receive said second liquid; a secondary conduit of smaller diameter projecting into said inlet end of said primary conduit; nozzle means for introducing said first liquid connected to the downstream end of said secondary conduit; and a gravity separator connected to the outlet of said first conduit for separation of said first liquid and said second immiscible liquid into a first liquid layer and a second liquid layer; and a plurality of elongated fibers extending generally linearly along and filling the cross-sectional area of said first conduit's length downstream of said nozzle means, said fibers having an upstream end secured to said nozzle means and a downstream end extending beyond the primary conduit for immersion into separated first liquid layer in said gravity separator.
