' ilhis' invention 'relates to dephlegmating or bubble towers such as are used in the pr0-" I '10 partially condensed'as they ascend.
An important obj ecto'ft'the present inven- 7 tion is to provide abuhbletower havingithiat rpor-tionflof the same, above thepor'tl'on 'm' which theliquid oil-is'maintained 'at aigiven 15 level, laterally or horizontally enlarged,- thereby permittingeXpansionof the vapors, I
providing for' an increase inthe capacity of the fto'wer, and minimizing the likelihood of;
' carrying over those substances which impart ooreo1or and gravity to the product.-
v further object-is to generally simplify and improve the construction "and arrangement of the;louhloletrays, as well as themeans "TOr cOnduc ting the excess oil downwardly 25 from one "bubble trayito another. 1 1 7 still further object is to provide'means forefiectivelyr tardin the ascending Vapors and preventing excessive fbuhbling of the oil in-th'eb1'1hble trays.

;A series of bubble trays are placed jtransversely of the towercasing-soas to partition the latter, oneof the trays being relatively l A small and placedin the "top of thelower por- 7 tion 50f the' tow er casing, and the remaining] v trays heinglarger and placed in-spaced grelation one above another in the enlarged upper 7 portion 6 of the tower "casing, [as 'cleairly shown in Figure 1 I I Each bubble traygernbodies a pan '10 whose v bottom is provided with apertures'i'n are mountedtubular vapor risers 1 1, of in]- verted Jshape, which extend upwardly *zfor a'distance nearly corresponding tothe depth {at which it is desired'tof have thegasoline' ac cumulateyand then extending downwardly o to a point above but adja'cent lthebfottfo 16f b e therefore, pass I through the vapor risers and ay b v W er the me W -Sees epea The rims ofthe pans 10 are offgreater-height.

bling ofthe oil or gasoline init'he pan Y c Each plate 12'has a central opening in which is secured the upper end of 'ajtube 13 which projects downwardly throughlthe associatedoradjacent pan 10 and has downint'jothe lower portionb of the tower casing;
on: I a'predetermined level in said lower'por tion' i tend into and terminate below the oil orgasoline level in the next lower bubble pan, extending through the plate 12 on the rim of said pan. By these means the oil or gasoline is maintained to the desired level in the hubble, pans, and excess oil or gasoline is conducted downwardly from one pan to another and into the lower portion of the tower casing. 7 A pipe 15 communicates with the tower casing above the lower bubble pan in the enlarged upper portion (3 and this pipe is used to draw oif reflux for further treatment or for being discarded, as the case may be.
A further pipe 16 enters the top of the tower casingfor conducting gasolineor oil into the latter so that the desired tcmperature or end point may be maintained in the upperportion of the tower above the bubble pans. This supply of oil or gasoline is also used to build up reflux in the apparatus, and mounted in the top of the tower casin is a oerforated horizontal oartition 17 i a: y ls l l which is spaced above the uppermost bubble pan and below the outlet of pipe 16 so as to spread the gasoline or oil laterally-as it passes from the pipe 16 into the tower..
'The general operation is old and well un-- derstood in the art, and as the functions of the novel features have been clearly pointed out above, further detailed description is believed unnecessary. However, it may be particularly noted that the ascending vapors are allowed to expand in the enlarged upper portion 6 of the tower, thereby enhancing the distilling operationand increasing the capacity of the tower. Moreover, the construction is extremely simple and durable, insuring etiicient operation and economy in manufacture. Still further, the spreading of the oil or gasoline introduced into the top of the tower enhances the condensing action atthis point, and the foraminous covers for the bubble pans prevent excessive bubbling and avoid entraining of undesirable substances in the ascending vapors.
Minor changes may be made without de parting fromthe spirit and scope of the invention as claimed.
-What I claim as new is:
1. In a bubble tower for dephlegmating hydrocarbon oil vapors, a bubble tray comprise ing a pan having apertures in the bottom thereof, inverted J-shaped vapor risers mounted in said apertures and extending upwardly and thendownwardly to points adjacent but above the bottom of the pan, a foraminous cover plate on the pan overlying the vapor risers, and means for conducting excess oil from the upper surface ofthe cover plate downwardly through the pan.
