Abstract
Abstract A volatile liquid component contained in a liquid is continuously extracted therefrom by volatilizing the component while the liquid is forced to flow through an elongate container. The liquid to be purified is fed into the container at lengthwise spaced points thereof and the volatilized component is removed from the container through ports at intermediate points thereof. The remaining liquid now liberated from the component is discharged at one end of the container. There is also disclosed a device for carrying out the method.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
174 words
A device for continuously extracting a volatile liquId component contained in a liquid, said device comprising in combination: an elongate treatment container having a discharge port at one end; rotary screw conveyor means within said container for force feeding liquid to be treated within the container toward said discharge port to effect volatilization of the volatile component contained in the liquid as the same as flowing through the container; a plurality of feed conduits communicating with said container at axially spaced feed points thereof for feeding the total volume of the liquid through said conduits into the container in the form of several fractional flows; and discharge means for discharging the volatilized component from the container, said discharge means including discharge conduits separate from the feed conduits and communicating with said container at lengthwise spaced points thereof, each of said discharge points being associated with one of said feed points and located downstream of the respective one of said feed points, the liquid freed of the volatile component being discharged through said discharge port.
Claim 2
Dependent Claim
16 words
The device according to claim 2 wherein conveyor means comprises two mutually parallel meshing conveyor screws.
Claim 3
Dependent Claim
30 words
The device according to claim 2 and comprising metering means connected to at least one of said feed conduits for supplying a metered volume of liquid through the respective conduit.
Claim 4
Dependent Claim
15 words
The device according to claim 2 wherein said container is divided into lengthwise spaced sections.
Claim 5
Dependent Claim
27 words
The device according to claim 5 wherein one of said sections communicates with at least one of said feed conduits and at least one said discharge means.
