Title: Improvements in or relating to electric treaters for emulsions
Inventor: TURNER DELBER W
IPC: C10G33/02
Filed: 1959-01-14
Abstract: <PICT:0894679/III/1> <PICT:0894679/III/2> An electric treater for emlsions having an external phase of oil with oil-immiscible material dispersed therein comprises a container divided into a primary treating zone 18 and a secondary treating zone 19, the zones being connected by a conduit consisting of a collector pipe 80, an upright portion 83 which serves to reinforce a partition 17, and an outlet portion 84. Suspended by insulators 35 in the primary zone 18 is an upper electrode 20 comprising a plate 26 having a central opening.  A lower electrode 21 includes concentric electrode rings 47 which provide circular spaces through which some of the material coalesced by the electric field can drop.  An alternating or uni-directional potential can be applied to the electrodes and as shown, a transformer 51 is used.  The emulsion is introduced between the electrodes as a thin sheet discharging radially outward from an annular orifice 54 of a distributer 55 supported on a riser pipe 56. When desalting a pipeline oil, an emulsion is formed by pumping fresh water 60 into a line 58 through which the oil flows, the emulsion being formed in a mixing valve 59 and passing up to the pipe 56.  The coalesced material settles below the line A-A and the treated oil rises to the top of the zone 18 but unresolved emulsion in the form of sludge forms between lines A-A and B-B.  The resolution of the sludge is aided by circulating it through perforated radial pipes 66, inlet manifold 65, pipe 69, pump 68, pipe 70, outlet manifold 71 and perforated radial pipes 72.  A further aid comprises nozzles 77 for discharging steam or other hot aqueous medium into the liquid below the level A-A.  The secondary treating zone 19 is provided with two spaced electrodes 91, 92 each consisting of a plurality of equally-spaced parallel metal strips.  Electrode 91 is suspended from insulators 102, and electrode 92 from insulators 106.  Rods 108 which ensure lateral rigidity of the electrode 92 may be of insulating material if the electrode is not to be at the same potential as the container; otherwise they may be metal.  Unidirectional potential is obtained from a transformer 112 and rectifier 113.  The emulsion, after entering the zone 19 via the pipe 84, is discharged from perforated pipes 131 and spread by means of notched units 125, the resulting streams then passing through the treating spaces between the electrodes 91, 92.  The coalesced material is removed from a pipe 150 and the treated oil is withdrawn through a pipe manifold 140.  A modification, Fig. 8 (not shown) includes three treating zones and is suitable for the successive acid and alkali treatment of a petroleum distillate or fraction.  The electrode sets may be energized from the same transformer.

Title: Improvements in or relating to electric control arrangements employing saturable reactors
IPC: H03F9/02
Filed: 1946-01-17
Abstract: 618,957. Non-contact-making relays. ELECTRO METHODS, Ltd., BUTCHER, F. E., and WILLHEIM, R. Jan. 17, 1946, No. 1630. [Class 40 (iv)] [Also in Group XXXV] The invention relates to the control of alternating current by a saturable reactor having A.C. or reactor windings 1, 1<SP>1</SP>, D.C. or control windings 3, 31 and feed-back windings 2, 21 carrying a rectified proportion of the alternating current in the load circuit, e.g. a resistance L. Fig. 1 shows the fundamental circuit without the reactor core or cores and Fig. 3 shows the characteristic curve of the arrangement, ordinates showing A.C. and abscissµ D.C. Without current in the control windings 3, 3<SP>1</SP> the feed-back ampere-turns establish a working point A and the control D.C. shifts this point to B or C, for example. In order to reduce the A.C. flowing when no control D.C. is applied, the invention provides a capacitor K connected across the A.C. windings 1, 1<SP>1</SP> or across windings coupled with them, whereby the curve ABC becomes shifted downwards on the A.C. axis; or provides an inductance to shift it downwards. In certain cases both may be used. A D.C. biassing excitation may be added as by windings 5, 51 connected with a source V and control means Z, whereby the curve may be shifted along the D.C. axis also, and the slope of the curve may be changed, as by shunting or otherwise modifying the feed-back windings. By such means any part of the characteristic curve may be made the initial working point. Since the capacitor K may be regarded as a source of injected current, it may be replaced by any means for injecting A.C. in suitable phase into the windings 1, 1<SP>1</SP> and Fig. 9 shows a choke CH (with saturable core) supplied with reversed phase current from an auto-transformer; this injected current is preferably equal to the magnetizing component of the controlled A.C. and the compensation thus obtained may be rendered complete by making the magnetic circuit of the choke a replica of that of the control reactor. To overcome any disturbance in balance between the voltages on the A.C. windings 1, 1<SP>1</SP>, short-circuited balancing windings 6, 6<SP>1</SP> in series with each other are placed on the same cores as the other windings; these windings also exclude residual voltages across the feed-back windings and relieve the control windings of A.C. components, besides enabling the feed-back windings to pass rectified current for the whole of each A.C. cycle. Specification 619,037 is referred to.
