Abstract
In its simplest sense, the present invention provides a method and apparatus for improving the contacting of plural, distinct phases in a circulatory reactor containing a liquid-immersed circulation tube by injecting a stream of dispersed distinct phases together into the circulation tube of the circulatory reactor. Sufficient fluid movement will force the fluid in the reactor to circulate downwardly through the circulation tube and upwardly in the annular space between the tube and the reactor wall.
Claims6
An apparatus for contacting of distinct fluid phase comprising:
- a cylindrical vessel having a top fluid inlet and a bottom fluid outlet;
- a circulation tube having a predetermined diameter centrally disposed in said vessel and immersed in a liquid contained therein under conditions of use;
- baffle means horizontally disposed within the vessel between said circulation tube and said bottom fluid outlet, the baffle means having a diameter equal to about the diameter of the circulation tube;
- an annular space defined between said circulation tube and said vessel;
- nozzle means extending downwardly from said top fluid inlet into said circulation tube, the nozzle means communicating with the top fluid inlet;
- a conduit providing communication between the top fluid inlet and the nozzle means, the conduit including means for generating bubbles of one distinct fluid phase in the other and
- for feeding two distinct fluid phases into said nozzle means for ejection into said circulation tube whereby said fluid phases and said liquid in said vessel flow downwardly through said circulation tube and upwardly through said annular space after being deflected by the baffle means.
