Title: Process for the manufacture of carbon black
IPC: C09C1/50
Filed: 1961-05-09
Abstract: <PICT:0925914/III/1> Carbon black is produced by burning a fuel gas in a combustion supporting gas to produce hot combustion gases, pyrolytically converting a portion of a hydrocarbon feed stream to carbon black and gas by contacting the vapourised feed with the hot combustion gases in a reactor, recycling to the reactor a portion, e.g. 1-50%, of the carbon black in suspension in the fuel and/or combustion-supporting gas streams to the reactor and recovering the remainder of the carbon black.  A portion of the collected carbon black may be recycled in suspension with the combustion supporting gas, i.e. air.  A portion of the carbon black reactor effluent gas, which contains suspended C black, a portion of which may be recovered, may be recycled in the fuel, and/or air or O2 feed streams to the reactor.  Part of the effluent gas containing H2 and CO may be recycled as fuel. Combustion-supporting gas, e.g. air, 1, is fed by blower 1a via 2 and 3, and natural gas, 4, is fed via 5 and 6 to C black reactor 7 supplied by feed oil by 62 as a spray.  Effluent from 7 flows via refractory connection 8 to 9 where quench water is sprayed or cooling is by a heat exchanger using air at 9a and C, which can then be used to preheat the oil, gas or air to the reactor or to dry the pelletized C.  Gas from 9 enters, via 10, 11 and 13 where most of the C black is removed, the remainder being removed in 15. Gas from 15 enters 17, via 16, where H2O vapour is condensed, H2 separated, e.g. by gas diffusion membrane cells, CO2 removed by scrubbing with monoethanolamine, CO removed by scrubbing with ammoniacol cuprous acetate and C2H2 separated to leave pure N2, which together with the H2 can be used for NH3, H2 and CO can be used for CH3OH.  Purified H2, CO2 and N2 can be bottled.  Fan 19 discharges tail gas via 18 and 21 and can be located in duct 16.  Effluent gas containing C black can be recycled from duct 8 via valve 48 and line 47 to 42; from duct 10 via valve 46 and line 45 to 42; from duct 14 via valve 44 and line 43 to 42; or from duct 16 via valve 41 to line 42 when the gas contains no C black.  Gas from line 42 is fed via valve 55, condenser 50, valve 56, line 49 to fan 57.  50 is H2O or air cooled at 51, 52 and removes H2O vapour, and can be by passed via line 53.  Gas from 57 passes via 58 and valve 59 to 60 where it may be mixed with air via valve 61 or natural gas via 63 or O2.  Weighing belt 39 may recycle C black from centrifugal settling tank 24 via 38 to conveyer 40 and then to 60 where the C may be mixed with the effluent gas.  Part of the effluent gas and the C black flows from 15 via hoppers 15a to pneumatic conveyer 21 which passes under cones 13a and 11a carrying C black to tank 24, where C is separated and the gas returned to 11 via 25 and 10.  C from 24 is fed via 24a and 26 to wet pelletizing equipment (not shown).

Title: Improvements in or relating to the extraction of tin from ores and the like
IPC: C22B1/08
Filed: 1932-06-15
Abstract: In the extraction of tin from ores or concentrates by chloridization by calcium chloride in the presence of carbon, the ore particles are bonded with a solution of calcium chloride into a pasty granular form, whereby dusting is prevented during chloridizing.  The ore, carbonaceous material, and chloride solution may be ground together to the consistency of wet sand, and the mixture dried to remove free water in a rotary furnace, whereby non-dusting agglomerates are formed.  Chloridization with distillation of tin as chloride is then effected in a muffle furnace with or without rabbling of the charge. The distillate is condensed to form a solution from which tin may be recovered by electrolysis, the recovered chlorine being converted to calcum chloride with or without calcium hypochlorite for re-use, or to hydrochloric acid by passage together with a hydrogenous reducing gas over a contact agent such as firebrick heated to redness.  The residues from the chloridizing furnace are leached to recover calcium chloride, which is used in excess.  Enough carbon is used to reduce all metallic bases present to metal.  A flow sheet for the process is included in the Specification. Specification 56/12, [Class 1 (iii), Oxides &c. Metallic], is referred to.  The Provisional Specification refers to Specifications 276,743 [Class 1 (iii), Oxides &c. Metallic], and 403,122.
