15 Claims. or. 202-454 This invention relates to distillation of a distillable material. a method of introducing a distillable material into a distillation zone or vessel. In another of its aspects, the invention relates to a method for controlling or preventing flow of non-vaporized material, along the inner walls of a distillation vessel, into a distillate receiving section of said vessel. In still another aspect of the invention, it relates to the provision of apparatus with which to carry into practice the methods ofthe invention.
According to the invention there has been provided amethod for distillinga distillable material which comprises introducing said material under distilling conditions substantially tangentially into a substantially-horizontally disposed distilling zone. In one form of the invention the distillable material is introduced in a substantially vertical, preferably and upwardly, direction and more preferably after it has travelled around the inner wall of said vessel, or the flash section thereof, is caused to impinge upon a flow arresting element or baflle to deprive it of. its momentum and to cause it to accumulate at a low point of the vessel from which it can be withdrawn.
Also, according to the invention, there is provided a method for distilling a distillable material which comprises introducing a distillable material into a substantially horizontally disposed distillation vessel and causing nonvaporized residue which travels downstream along the inner walls of said vessel to impinge upon a peripheral flow arresting means arranged around the inside of said vessel downstream of the introduction of the feed.
Still according to the invention, the feed canbe introduced into a flash drum or section provided within the distillation vessel, as .will be evident from a more detailed description of the methods of the invention and several embodiments of apparatus suited to a practice of the same.
In the drawing, Figure l is a perspectiveview of apparatus showing partly cut away the feed end of i a distillation vessel containing a tangential flow arrestor baffle according to the invention and to which vessel the feed is tangentially introduced. Figure 2 is a cross-sectional view along line 2-2 of Figure 1 showing an axial direction flow arrestor according to the invention. Figure 3 shows a vertical cross-sectional view of a vessel containing a verticalflash drum or section to which the feed is: also tangentially introduced. Figure .4 is a top view of a horizontally taken cross-section passing substantially throughthe axis of the vessel of Figure 3. Figure 5 shows partlycut away a horizontally disposed flash cylinder or section in a distillation vessel. The cylinder is equipped with a tangential flow arrestor baflle as well as an? axial direction flow arrestor which can be seen in Figure6, which is a vertical cross-sectional view of Figure 5 along the line 6-6, Figure 7 is a vertical cross-section of Figured alongthe line 7--7; Figure 8 is a perspective view of apparatus showing the feed end of a horizontal distillation vessel containing a tangential flow arrestor baflle according to the invention, the central portion of the In one of its aspects the invention relates to t 2,843,534 Patented July 15, 1958 vessel being partly cut away and showing an axial direction liquid flow arrestor according to the invention, a condensing element located downstreamof the axialdirection liquid flow arrestor, and condensate and vapor outlets at the downstream end of said vessel.
Referring now to Figure 1, a distillable material, which can be a hydrocarbon, vegetable or mineral oil, fruit juice, organic or inorganic chemical solution, etc., is introduced through pipe 10 which is tangentially affixed to, and therefore communicates tangentially with, distillation vessel 11. The material introduced possesses a suflicient momentum to cause it to flow tangentially upwardly along the wall of vessel 11 until it impinges upon batfle 12 from which it falls to the bottom of vessel 11 and is withdrawn ultimately through outlet pipe"13. Battle 12 prevents impingement of the entering; liquidupon the film of liquid which were baffle 12 absent would flow across the end of inlet pipe 10. In the figure, as shown, the liquid moving around the inner wall of vessel 11 would, because of its momentum carry up over theend of inlet pipe 10 the residue accumulating in the bottom of vessel 11. Owing to the rush of vapors toward the downstream end of vessel 11 some of the non-vaporized material will travel in an axial direction toward said end ofvessel 11. To prevent non-vaporized liquid or material from leaving the flash section of vessel 11 there is provided a ring 14(Figure 2) which arrests the flow of liquid along the wall causing said liquid to accumulatein the bottom of the vessel 11 and ultimately to be Withdrawn through pipelS. Vapors which pass beyond ring 14 can be removed from vessel 11 through pipe 15. If desired, as shown in Figure 8 the vapors can be condensed in vessel 11 by means of a condensing coil (not numbered), in which event a liquid distillate is withdrawn through a withdrawal pipe which is also not numbered, for sake of sirnplicity. Internals and other arrangements which can be combined with a vessel according to this invention are described and claimed in copending application, Serial No. 343,560, filed March 20, 1953, now Patent No. 2,805,981, by Victor C. Cavin et al., and Serial No. 241,183, filed August 10, 1951, by Paul M. Waddill.
In Figure 3 the distillable liquid or material is tangentially introduced through pipe 20 in vertically disposed cylinder 21 within a vessel 22 which can be like vessel 11. The tangential introduction causes the liquid to. flow tangentially within'the cylinder and to spread out upon upwardly-over anddownwardly on its wall. There being here no momentum in the downstream direction of vessel 22, non-vaporized liquid flows. downwardly on both the inside and outside walls of the cylinder and collects at the. bottom. of vessel 22 from which it iswithdrawn through pipe 23. i
In Figure 5, feed is tangentially introduced by pipe 30 into horizontally disposed. flash cylinder 31. in vessel 32, equipped with a ring 33 (see Figure 6) and baflle 34- (see Figures 6 and 7) and non-vaporized liquid drops from the lefthand endof the cylinder into the bottom ofthe vessel and is withdrawn through pipe35. Vapors are taken overhead through pipe 36.
In Figures" 3 and 5 the cylinders 21 and31 can be welded to the drums 22 and 32, respectively, by suitable extensions thereupon and, if desired, the bottom end of drum 21 can extend at least low enoughto be in the liquid level duringoperation. If the extension of cylinder 21 is complete so that oil therein flows directly through outlet 23, without further contact with the interior of drum 22, then suitable additional oil liquid outlet for liquid collecting at the bottom of drum 22, outsideof cylinder 21, is provided.
Reasonable variation and modification. are; possible within the scope of the foregoing disclosure, drawings and the appended claims to the invention, the essence of which is that a method and apparatus for tangentially introducing a distillable material into a horizontal distillation zone; arresting tangential flow on the walls of said zone; arresting axial direction liquid flow on the walls of said zone; flashing a distillable material within a flash zone, cylinder or section disposed within a distillation zone, either vertically or horizontally; and in the case of the horizontal flash section (cylinder) equipping it with a tangential flow arrestor and/ or an axial direction liquid flow arrestor; have been set forth and described.
