Title: Improvements in or relating to the production of catalytic cracking feed stock from petroleum residues by vacuum flashing and apparatus therefor
IPC: C10G7/06
Filed: 1957-07-22
Abstract: <PICT:0815881/III/1> A process for the continuous recovery of catalytic cracking feed stock from a petroleum residue by passing it through a heating zone the exit of which is maintained under sub-atmospheric pressure comprises heating the petroleum residue in said zone to a temperature at which the residue is largely but incompletely vaporized, passing the mixture of vapours and unvaporized liquid residue at sub-atmospheric pressure into a centrifugal separation zone, wherein the vapours are separated from the unvaporized liquid residue, passing the vapours upward from the centre of said centrifugal separation zone and through a foraminous mist coalescing zone, condensing the vapours after passing through said mist coalescing zone and recycling a portion of the resulting condensate by spraying it in a downward direction through the rising vapours at a point just below the foraminous mist coalescing zone. In a preferred embodiment reduced crude oil is passed into the coils of the heating furnace 3 by pump 2 and is partially vaporized at a temperature of about 430 DEG  C.  A vacuum is drawn through a line 4 by means of steam jets (not shown).  The heated reduced crude is then passed through the transfer line 5 into the centrifugal separator 6 built in the flash tower 7.  The mixture enters the tower tangentially below the plate 8 and the separated liquid descends to the bottom section 9 where it is lightly stripped with steam.  The vapours pass up through the central overflow pipe 10 into the upper section 11 containing a mat 12 and sprays 13.  The pressure in the region of the mat is about 80 mms. Hg.  Liquid coalesced in the mat and from the sprays collects on the plate 8 and is withdrawn through a line 21.  The vapours are withdrawn through a line 4 to a condenser 14 wherein the major part of the product is condensed as flashed distillate. Condensate is removed through a line 15 and part of it is passed through a line 16 to feed the sprays.  Vapours still remaining after passing through the condenser 14 and the separator 17 are further cooled by a condenser 18 to give a light gas oil in the separator 20 and exhaust gases through line 19.

Abstract: 1451564 Electric protective systems BBC BROWN BOVERI & CO Ltd 28 May 1974 [30 May 1973] 23649/74 Heading H2K An electric network protective device has a distance protection device 11 and an overcurrent protection device X connected on their output sides to a common network interruptor 3 and have their outputs controlled by a logic system 12, 13, 14, 15, 16, 16A, 17 which, in response to at least one of the signals received by the devices 11, X, falling below a set minimum, determines which device 11 or X remains operative. Current and voltage transformers 4 and 5 serve via circuits 6 and 7 to activate a selector circuit 8 which produces two voltage signals which are fed via a reference voltage source 9 and fault measuring voltage source 10 to the distance protection device 11. The overcurrent device X is fed via a further current transformer 4a and has an inverse characteristic which may be made steeper in the small current region and flatter in the longer current region, Fig. 3b, not shown) by a resistor (Fig. 2, not shown) across the capacitor feed back of an amplifier of the device X. With fault conditions such that the input signal voltages U 1  and U 2  to the distance devices are above the threshold settings of devices 12 and 13 signals are supplied to negating inputs of an OR gate 16a which with no output signal ensures that an AND gate 16 does not pass on a signal from the device X to the common OR gate 15. The signals from 12 and 13 are also fed to an AND gate 14 which, provided all three devices 12, 13, and 17 are above their threshold rating, allows the output signal from 11 to operate the interrupter 3 through the OR gate 15. If U 1  and/or U 2  falls below the threshold value of 12 or 13 the AND gate 14 blocks the output of 11 and gate 16a passes a signal to AND gate 16 permitting the output of X to be effective provided the signal to 17 is above the threshold value.
