Title: Improvements in or relating to the cracking of hydro-carbon oils
Filed: 1919-10-08
Abstract: 160,200. Holmes, R. C., and Manley, F. T. Oct. 8, 1919. Hydrocarbons, cracking; bulk evaporators; progressive evaporators. - In cracking oils by distillation under pressure, the oils are passed through a series of stills I, 2, 3, 4, Fig. 1, externally heated to a substantially uniform cracking temperature, the vapours from each still being condensed and collected. The vapours are led by pipes 36, 37, 38, 58 to a condenser 6, the condensate being returned by a pipe 60 to the bottom of the still 1. The remaining vapours are led by a pipe 61 to a condenser 62. A pressure of upwards of 75 lb. per sq. in., preferably 150-200 lb. per sq. in., is maintained by a vapour outlet valve 69. Residual oil is withdrawn more particularly from the still 4, by a pipe 39, and is led to a heat-exchanger 10 through which the crude oil passes before it is fed by a pipe 47 to the bottom of the still 1. The stills are provided with scrapers 72 mounted on shafts 71 passing through stuffing-boxes 75 through which cold oil is circulated at a pressure equal to that in the stills. The stills are arranged so that they project at both ends beyond the walls of the furnace 5, the pipes 33, 34, 35 for conveying the oil from still to still being fitted outside the furnace. The furnace is arranged to supply the greatest quantity of heat to the still 1. The combustion chamber 11, Fig. 2, comprises a bridge 12, a perforated inclined arch 13, and a secondary arch 14 providing openings into conduits 15. One part of the combustion gases flows around a heat-deflecting wall 16 and through chambers 23, 24, &c. constituted by perforated walls 20, 21, &c. A substantially uniform temperature is maintained by supplying the remainder of the combustion gases to the chambers 24 &c. from the conduits 15 under the control of dampers 29, 30, Fig. 4.

Title: Improvements in the manufacture of explosives
IPC: C07C201/02
Filed: 1934-09-06
Abstract: In the nitration of organic compounds involving heating or cooling of one or more of the reagents, temperature-controlling media are employed for the whole of such heating or cooling which are in indirect contact with the reagents and are inert to them or react to form innocuous products.  Explosion or fire through leakage from the heating or cooling system is thereby avoided. The media may consist of substances present in the reagents.  Thus in nitrating glycerine or glycol, the cooling medium is nitric or sulphuric acid or a mixture thereof having a water content substantially that of the nitrating acid.  The cooling medium may then be used to feed the nitrator.  Inert saturated aliphatic hydrocarbons or halogenated hydrocarbons, or solutions of nitrates and/or sulphates can also be used.  These are circulated between the cooling coils, jackets, or the like of the nitrator and a refrigerating machine.  Alternatively, an inert gas such as carbon dioxide or air may be employed.  For heating the glycerine, glycol, or mixture thereof, these compounds themselves can be employed.  The process is applicable to the nitration of benzene, toluene, xylene or other hydrocarbons.
