Title: Improvements in or relating to the production of olefines by the treatment of hydrocarbon oils at elevated temperatures
IPC: C07C11/02
Filed: 1942-06-17
Abstract: <PICT:0560195/IV/1> <PICT:0560195/IV/2> Heavy hydrocarbon oils are converted mainly into gaseous unsaturated hydrocarbons, e.g. ethylene, propylene, butadiene, and aromatic hydrocarbons, e.g. toluene, benzene and xylene by vaporising the oil in presence of super-heated steam, separating unvaporised constituents, and passing the vapors and gases through a conversion zone heated to 1200-1300 DEG  F., quenching the converted products with a condensate produced later in the process, fractionating the vapors to separate gasoline and gases from a condensate which is used as the quenching oil and further fractionating the gasoline and gases to recover ethylene. Crude oil, e.g. gas oil, is fed through line 10 and preheater 14 into a vaporising coil 18 in a furnace 22 and is mixed with superheated steam in the latter sections of the coil.  The mixed vapors and liquid pass to a separating tower 42 where liquids are separated through line 44.  Superheated steam may be added at the base of the tower through line 102.  The vapors pass overhead through line 48 to the conversion coil 55 and the cracked products are quenched in line 56 and then pass to a combined separator and fractionator 60, 62 where a condensate is collected on a tray 72 and recycled through line 74, 78 as quenching oil.  This oil is preferably cooled by passing it through cooler 14 where it preheats the charge and through cooler 32 where it preheats water passing to the superheating coil 37.  The condensate may also be cycled (a) through line 47 as reflux to tower 42 (b) through line 68 to the separator 60 (c) through line 96 to tower 62.  Vapors and gases passing overhead from tower 62 are collected in separator 112 and subjected to a series of compressions and separations in receivers 126, 142, 154 and compressors 136, 150 to obtain a liquid fraction which is fractionated in tower 174 to recover as bottoms an aromatic gasoline fraction recovered through lines 178, 184 and an over-head which is mixed with gases from receiver 154 compressed in compressor 201 and fractionated in tower 202 to separate ethylene and like gaseous fractions.  A combination type furnace for carrying out the various heating operations required comprises (Fig. 2) radiant and convection heating sections 232, 234 heated by roof burners 236, and end burners 240.  The oil is first heated in a preheating section 246, and is then divided into two, steam passing through tube banks 242, 244 and uniting in line 264. Steam is superheated and fed through line 252, 260 into the banks at 258, 262.

In an apparatus for generating an electric analogue quantity whose instantaneous value is substantially proportional to the square root of the sum of the squares of two other electrical analogue quantities, the latter analogue quantities are impressed as voltages on two distinct phases of a symmetrical multipulse A.C. to D.C. current converter circuit using unidirectional electronic valves while the resultant electric analogue voltage is tapped from the D.C. output circuit of the converter circuit. Fig. 1 shows 12 unidirectional rectifier valves 10 connected in a symmetrical 12-pulse A.C. to D.C. converter circuit with the 12-phase secondary winding 11 of a three-core transformer having biphase primary windings 12, 13 of which winding 12 is arranged on one core while winding 13 is shared between 2 cores; receiving two input analogue voltages, and arranged so that for equal sinusoidal inputs in quadrature all the core legs are equally magnetized. The valve cathodes are returned to a common point connected by a load resistor 14 to the neutral of the transformer secondary to develop a unidirectional load voltage which is shown by mathematics to be proportional to the square root of the sum of the squares of the instantaneous values of the input voltages irrespective of their individual magnitudes and phase angles. Fig. 2 shows a modification wherein primary windings 17, 18 of a 2-core transformer receive the input voltages, and respectively co-operate with two pairs of secondary windings 19, 20 and 21, 22, the outer ends of the former and inner ends of the latter being interconnected to opposite ends of load resistance 23. The windings are tapped at 0.5 and 0.866 of their lengths and the tappings are interconnected with unidirectional rectifying valves 25 to 32 and 36 to 39 in a complex network, it being shown that (as before) the unidirectional load voltage is proportional to the square root of the sum of the squares of the instantaneous magnitudes of the input voltages. The windings 19, 20, 21, 22 are stated to be replaceable by tapped potentiometric resistors upon which are impressed alternating or direct input analogue voltages.
