Title: Improvements in or relating to the selective extraction of aromatic and sulfur-containing constituents from hydrocarbon fractions
IPC: C10G21/10
Filed: 1951-01-26
Abstract: The raffinate phase from the solvent extraction of a hydrocarbon distillate with liquid sulphur dioxide, which extraction effects the removal of aromatic and sulphur-containing constituents from the distillate, is preheated before being passed to a fractionation system for the substantially complete separation of sulphur dioxide from hydrocarbons, the pre-heating providing approximately 30-70 per cent. of the heat requirement in the fractionation system.  If desired, the extract phase from the solvent extraction may be similarly treated.  The <PICT:0707396/III/1> <PICT:0707396/III/2> process permits simple separation of sulphur dioxide, without employing a multi-stage system of evaporators, and avoids excessive overheating of hydrocarbon constituents subjected to fractionation. In Figs. 1 and 2, kerosene, free of air and water, enters through line 2, Fig. 1, and is cooled in heat exchanger 3 and chiller 6, Fig. 2, before passing to extraction tower 1 through line 7.  Liquid sulphur dioxide is also withdrawn from chiller 6 and passes to extraction tower 1 through line 8.  The raffinate phase from tower 1 is removed through line 4 and, after being heated in heat exchanger 3 and preheater 10, is fed to fractionator 11, provided with sufficient plates to give a total of four or more theoretical plates.  A liquid stream is removed from fractionator 11 through line 12 and is passed to reboiler 13 and then returned in vapour form to the fractionator through line 14.  Liquid sulphur dioxide reflux enters fractionator 11 through line 55, while gaseous sulphur dioxide leaves through line 16. Hydrocarbons, free of sulphur dioxide, leave fractionator 11 through line 15 and, after being cooled in cooler 17, are given a caustic alkali wash in zone 18.  The extract phase from tower 1 is removed through line 9 and, after being heated in heat exchanger 22 and preheater 30, is fed to fractionator 31 which is operated similarly to fractionator 11.  The process may also be operated with two instead of one fractionation zone for each of the extract and raffinate phases treated.

Filed: 1927-01-31
Abstract: 289,926. Barr & Stroud, Ltd., and French, J. W. Jan. 31, 1927. Optical apparatus.-The field of view of the apparatus described in Specification 287,608 is observed after being divided into two portions, each of which is limited to a particular displacement of the image with respect to a point of reference. The resulting fields of view may be observed in separate eye-pieces or may be separated from one another in a single eye-piece, and in the latter case one field may be oriented for facility of observation. The movement of the line 4, 5, Fig. 1, with respect to the line 9, 10 through the point of reference 6 is observed in one field and the movement of the line 2, 3 with respect to the line 7, 8 is observed in the other field. To view separate fields in a single eyepiece, one being rotated through 90‹, the arrangement shown in Fig. 3 is utilized. A reflecting surface 15 of the half-silvered or silvered grid type receives the rays from the projector lens 18 and divides them so that part passes by way of the reflecting surface 16, Dove prism 24 and surfaces 17 and 20 to the upper part of the image plane 21, and part directly to the reflecting surfaces 22, 23 and thence to the lower part of the plane 21. The prism 24 is positioned so that the upper field is rotated through 90‹. The two fields 25, 26, Fig. 4, are separated by an opaque strip 27 carrying fixed or adjustable index marks 28, 29. In the lower field the line 4, 5, Fig. 1, moves horizontally and in the upper field the movement of the line 2, 3 in a vertical direction along the line 9, 10, Fig. 1, appears as a horizontal movement in the field 25. When using separate eyepieces they may be placed in the lines of the direct and reflected rays from the surfac 15, Fig. 3, at right angles to one another, or parallel to one another as shown in Fig. 6. In the latter case an additional reflecting surface 33 is provided and the eyepieces 14<1>, 14 view images formed in planes 19<1>, 19 respectively. The marks 28, 29 may be on separate adjustable strips provided with scales to indicate the alteration of the index setting. To facilitate more accurate reading, the marks 28, 29 may be replaced by notches 36, 37, Fig. 8, slightly greater in width than the lines 3, 5, the adjustment being determined by the appearance of the spaces on each side of the lines.
