Title: Steel making converters
IPC: C21C5/34
Filed: 1972-01-17
Abstract: 1364792 Converter steelmaking CENTRE DE RECHERCHES METALLURGIQUES-CENTRUM VOOR RESEARCH IN DE METALLURGIE 17 Jan 1972 [18 Jan 1971 (2)] 2187/72 Heading C7D [Also in Division F4] Steel is made in a converter having one or more tuyeres opening at the internal surface of the bottom and one or more tuyeres in the side wall below the surface of the molten metal and opening at the internal surface of the side wall. Oxygen is injected through the tuyeres and the relative amounts of bottom and side wall injection are adjusted during the process. At the beginning of the process oxygen may be blown mainly through the bottom tuyeres until the greater part of the silicon has been oxidized. The relative amount of oxygen admitted through the side wall is then increased during addition of lime to maintain the slag in a fluid and oxidized state. When the lime addition is completed bottom blowing is increased to complete oxidation of carbon. The side wall tuyeres may be disposed to produce jets directed obliquely upwards, towards the centre of the converter and/or tangentially to impart rotary movement to the melt.

The sludge is guided to the apertures 6 by the inner surface of the element 12 and its discharge from the apertures 7 is assisted by the auxiliary liquid in the ring 8 supplied from the chamber 14. The pressure of this liquid may be adjusted so that little or no separated liquid is discharged with the sludge. This may be secured by means of regulating devices 22, 23 in the supply and discharge channels respectively of the auxiliary liquid.

Title: Solidifying normally liquid hydrocarbons
IPC: C10L7/02
Filed: 1944-02-08
Abstract: 576,180. Solidified liquid fuels. CLARK, D'A. M. (Safety Fuel, Inc.). Feb. 8, 1944, No. 2350. [Class 91] Normally liquid inflammable hydrocarbons are solidified by the formation in situ of a voluminous gel of a metallic soap, by reacting a saponifiable compound in solution in the hydrocarbon with a saponification agent which is suspended in the solution in a dry pulverulent form, the reaction mixture being maintained in a quiescent condition for at least the last stages of the reaction. The mixture is preferably agitated in the earlier stages (a colloid mill may be used) to the point where the viscosity is sufficient to maintain the particles of the unreacted saponification agent in complete suspension, so that no segregation of the particles occurs during the quiescent stage. The saponifiable compound may be a saponifiable acid or its salt, the reaction being one of neutralization or of double decomposition. Slight heating may be used if desired. Completion of the solidification occurs during the quiescent stage which may be effected after the mass is discharged into the fuel containers. Hydrocarbons specified comprise petroleum distillates, naphtha, benzol, and light coal tar distillates. The saponifiable compounds comprise fatty and rosin acids 'and their salts or mixtures of the same such as coconut oil fatty acids. Rosin or stearic acid or a mixture thereof are preferred. The saponification agents specified comprise hydroxides and alcoholates including glycolates, particularly the sodium compounds. A small proportion of free alcohol may be added to expedite the reaction. Only a proportion of the saponifiable compound may be used, the remainder being added in stages.

Title: An improved process for purifying hydrocarbon mixtures with removal of paraffin wax
IPC: C10G73/06
Filed: 1935-01-24
Abstract: <PICT:0432168/III/1> Mineral oils are purified and dewaxed by adding a solvent mixture consisting of 15 to 35 per cent by volume of liquid sulphur dioxide and the remainder an auxiliary solvent consisting of an aromatic hydrocarbon or other low boiling solvent such as ether or chloroform which is miscible with sulphur dioxide, and after chilling the mixture separating the precipitated wax.  Before or after dewaxing the oil is treated with a similar solvent mixture containing a higher proportion of sulphur dioxide or with sulphur dioxide alone. Mineral oil such as a lubricating oil distillate or residue or brown coal oil passes through a pipe 1 to a mixing chamber 3 to which benzene is admitted through a pipe 2.  The resulting solution is mingled with a mixture of equal parts of benzene and sulphur dioxide flowing through a pipe 4 from the settling chamber 5.  The liquids are agitated in a mixer 6 at 10 to 15 DEG  C. to form a solution which passes through a heat exchanger 7 at about 0 DEG  C., and a second heat exchanger 8 at about -20 DEG  C., to a final cooler 11, where the temperature is reduced to -30 DEG  C., by evaporating part of the sulphur dioxide The precipitated wax crystals and mixed liquids containing about 34 per cent of sulphur dioxide is forced by a pump 14 through a filter 17 where the wax is removed.  The filtrate passes to a separating chamber 9 together with additional sulphur dioxide at 20 DEG  C., admitted from a heat exchanger 19 and pipe 18, whereby the liquid containing equal amounts of sulphur dioxide and benzene, separates into layers.  The raffinate is drawn off through a pipe 22 and mixed in a chamber 23 with a further amount of benzene and sulphur dioxide admitted from a pipe 24 and passes to the final separating chamber 5 at -20 DEG  C.  The dewaxed and purified lubricating oil is drawn off through a pipe 26, and is freed from sulphur dioxide, and the extract flows to the heat exchanger 7. Benzene may be replaced by toluene or other homologues of benzene or by chloroform or ether. Chilling may also be effected indirectly by the evaporation of propane.  The extraction stages after dewaxing may be effected by counterflowing the liquids.

Title: A process for the separation of monoalkyl phosphates from dialkyl phosphates
IPC: C07F9/02
Filed: 1954-01-29
Abstract: Monoalkyl phosphates are separated from dialkyl phosphates, the alkyl groups containing not less than 5 and not more than 18 carbon atoms, by converting the monoalkyl phosphates and dialkyl phosphates into their alkali metal salts and dissolving the alkali metal salts of the monoalkyl phosphates from the mixture of salts by subjecting the mixture of salts to extraction with water.  The process may be carried out in a modified form by converting the monoalkyl and dialkyl phosphates into their alkali metal salts in the presence of sufficient water to dissolve the alkali metal salts of the monoalkyl phosphates and removing the insoluble alkali metal salts of the dialkyl phosphates from the solution. The process is particularly suitable for the separation of monoheptyl and diheptyl phosphates and monononyl and dinonyl phosphates.  The alkali metal salts are preferably the sodium salts but the potassium and lithium salts are also readily separated.  The separation is preferably effected at a pH value of at least 10.  Examples are given for the separation of the mono and dialkyl phosphates obtained by the reaction of phosphorus pentoxide with 3,5,5-trimethyl hexanol and with n-heptanol-1 respectively using a normal aqueous solution of sodium hydroxide in accordance with the modified form of procedure described above.
