Patent GB-466682-A (GB)
Title: Improvements in and relating to the cracking of hydrocarbon oils
Filed: 1935-10-29
Abstract: In two-stage cracking processes in which in the first stage the oil with products obtained <PICT:0466682/III/1> from the process is cracked in the liquid phase under mild "viscosity breaking" conditions and the cracked products separated into liquid and vapours which latter in the second stage are cracked in the vapour phase, the liquid residues of low carbon/hydrogen ratio from the second cracking stage are rejected but the residue from the first stage is flashed and the vapours obtained are condensed and used as recycle stock for the first stage.  Crude oil is passed through a line 1 into a fractionator 3, from the bottom of which reflux is drawn off and passed through coils 5<1>, 7 comprising the first cracking zone into an evaporator 11.  Vapours from the vessel 11 are passed at about 1000 DEG  F. through the coils 13<1>, 14, 8 comprising the vapour phase cracking zone and thence through a line 15 to a conversion arrester 17 fed with condensate supplied through a line 18 from the tower 3 and cooled in a heat exchanger 18<1>.  The products from the arrester 17 are flashed in a tower 25 and the vapours evolved are passed through a line 26 into the tower 3 while the residues are removed through a cooler 27<1> to storage.  The primary residues pass from the evaporator 11 through a line 29 to a still 31 heated by a steam coil 31<1> or maintained under vacuum by a steam jet 32<1>. The vapours evolved pass through a line 33 to a condenser 34 and the condensate is collected in an accumulator 35 from which it is pumped through a line 40 to the column 3.  In a modification, the distillation of the primary residues is effected under a vacuum obtained by connecting the pipe 33 through a Venturi nozzle to the pipe 26.  The vapours passing off from the top of the tower 3 are condensed and freed from gases which are compressed, and the condensates obtained are stabilized in a tower 67 provided with a reboiler 69 to which heat is supplied by circulating therethrough a hot fraction cycled from the tower 3 through lines 67<1>, 68. Specification 412,461 is referred to.

Patent GB-411094-A (GB)
Title: Improvements in the production and treatment of natural and artificial filaments, threads, foils and similar materials
IPC: D01F2/28
Filed: 1932-10-28
Abstract: Processes such as wet spinning, stretching, shrinking, or saponification wherein natural or artificial filaments, yarns, threads, or other textile materials or foils, films, or similar materials are treated with a bath of liquid medium containing a volatile constituent, are operated with the surface of the treating medium substantially covered with a layer of liquid substantially immiscible with such medium, and the materials are withdrawn from the bath so that, as they issue from the bath they do not contact with the said layer of liquid.  Preferably the materials are also prevented from contacting with the immiscible layer as they enter the bath and preferably the volatile constituent of the bath is also the active agent therein.  When rollers or other devices are employed which rotate in the bath, and which are only partly immersed or which are near the lower surface of the immiscible layer partitions are provided which extend below the surface of the coating layer to keep the surface of the bath in the vicinity of the roller clear.  In one example, a number of cellulose acetate threads are led in warp formation under a feed roller immersed in a stretching bath consisting of a 48--50 per cent aqueous solution of dioxane contained in an open vessel about 100 feet long and covered with a coating of paraffin about \ba1/8\be inch deep.  At the far end the threads are withdrawn in contact with a draw roller rotating at such a speed that they are stretched to 400--500 per cent of their original length. They are then washed, dried and wound.  Partitions extend across the bath on the side of the feed roller opposite to that at which the threads enter and on the feed side of the draw roller, and maintain the surface of the softening liquid in the vicinity of the rollers free from paraffin to prevent contact between the threads and the paraffin.  In a second example a warp of cellulose acetate threads passes from a creel of bobbins into an open saponifying bath of aqueous ammonia covered with a \ba1/4\be inch layer of medium paraffin to prevent evaporation.  The threads are introduced and withdrawn without contacting the paraffin and are washed, dried and wound.  Specifications 323,790, 336,217, [both in Class 2 (ii)], 370,430, 371,461, 380,504, and 389,823 are referred to.  According to the Provisional Specification the threads may contact with the layer of immiscible liquid as they leave the bath, and the layer may itself have some action on the materials and may contain dissolved constituents.  Thus the coating liquid may remove a size or dressing from the threads or may lubricate them.  In the Provisional Specification in addition to the Specifications mentioned above, Specifications 177,868, 179,234, [both in Class 2 (ii)], 340,324, 340,325, 340,436, and 340,437 also are referred to.
