Patent GB-359025-A (GB)
Title: An improved process for the conversion of hydrocarbons into lighter hydrocarbons
Filed: 1930-07-15
Abstract: In a process for obtaining low-boiling products from petroleum oils, the feed oil from A, preheated at C if desired, is passed under high pressure through a coil or coils G, H, K in which it is subjected to cracking temperature for a short but sufficient time, not less than 2 minutes, to obtain the maximum conversion possible without formation of carbon, and the cracked products are passed to a vaporizer D under reduced pressure, the temperature of the stream entering the vaporizer being 580-750 DEG  F. so that most of the uncracked intermediate products will vaporize without further cracking.  The vapours are withdrawn at L and the intermediate condensate which collects at N is recirculated through line P to the inlet of the coil G, H, K, or through branches such as Q to intermediate points, or through R to the outlet of the coil K.  The residue from the vaporizer is withdrawn at M.  In a modification (Fig. 2, not shown), the feed oil is admitted directly to the vaporizer, the intermediate condensate is passed through the cracking coils under similar conditions, and the cracked products are introduced into the vaporizer at similar temperatures to those stated above.  In both processes, the cracking temperature may be <PICT:0359025/III/1> 750-1250 DEG  F., and the pressure 150-3000 lbs. per sq. in. or more, while the vaporizer is at a much lower pressure, perferably atmospheric.  The temperature of the products entering the vaporizer, or the temperature in the lower part of the vaporizer may be regulated by the introduction of cooler oil such as the intermediate condensate or suitable oils obtained from other parts of the system, or by by-passing a part of the cracking coil as at U.  The temperature at the upper part of the vaporizer is regulated by cooling coils, which may be independent of the feed oil, so that only light cracked vapours are withdrawn.  The intermediate condensate from the vaporizer may be treated in a still before recirculating; the residue from the vaporizer may be recirculated, or it may be submitted to destructive hydrogenation, directly or after treatment in stills, and the vapours from the vaporizer and from the various stills may be worked up for gasoline and other products, all as described and illustrated in Specification 359,022.  The vaporizer may be constructed as shown in Fig. 5 of that Specification.  The vapours and gases not condensed may be submitted to dissociation temperatures and used in destructive hydrogenation.  The hydrocarbons treated in the coil may be converted largely in the vapour phase. Specifications 359,023 and 359,026 also are referred to.
