Patent GB-436194-A (GB)
Title: A process and solvent for separating mineral oil products
IPC: C10G21/12
Filed: 1935-04-29
Abstract: Mineral oils are separated into their paraffinic and naphthenic components by treating with an anhydrous mixture of crude cresol and a liquid water-repellent solvent, whereby paraffins are removed, and then saturating the extract with water to separate the naphthenic component leaving an aqueous mixture of solvents containing resins, aromatic and asphaltic substances.  The major part of the aromatic and resinous fraction may be removed in a pretreatment with a mixture of the solvents containing water whereby a more pure naphthenic fraction is obtained.  A mineral lubricating or spindleoil distillate or a residue is treated with three portions of a mixture of cresol containing 10 to 30 per cent by volume of nitrobenzene at or near atmospheric temperature, or the oil is completely dissolved by warming with the solvents and then cooled to separate into layers. After removal of the paraffinic layer the solvent layer is saturated with water by passage through a pump and the naphthenic layer is separated in a centrifuge and the separated naphthenic and paraffinic fractions p  are distilled to remove solvent and are finally treated with an adsorbent earth.  Final traces of solvent are removed by superheated steam.  The naphthenic fraction may be further purified by extraction with anhydrous solvent mixture at a low temperature. The aqueous mixture of solvents is distilled removing water and solvents, leaving an asphaltic oil.  Water repellent solvents specified are:--nitrotoluene, nitrobenzene, toluidines, aniline, xylidines, ethyl aniline, dichlorbenzenes, or dichlordiethyl ether. The separation may also be effected by counter-flowing the oil and solvent mixture in a treating tower. Specification 432,249 is referred to.

Title: Process for utilising coal residues
IPC: C04B7/28
Filed: 1971-05-04
Abstract: 1348061 Cement L TRIEF 4 May 1971 [4 May 1970] 12946/71 Heading C1H [Also in Division F4] A cement is obtained by heating a mixture of coal residues and CaCO 3  at a temperature below that at which it softens, raising the temperature to at least 1500‹ C. to form a molten slag which is rapidly water cooled and granulated which is then ground. The coal residues can be fly ash or mining detritus. Additions to the cement are crude ash, and hardeners, e.g. NaOH, Na 2 SO 4 , CaSO 4 , Na 2 CO 3 . When more than 4% Fe 2 O 3  occurs in the coal residues a third heating to 1800‹ C. is made whereby metal separates from the slag and is removed thus purifying the slag which transforms it into a "white" binder.
Patent GB-356172-A (GB)
Title: Improvements in or relating to the refining of wax-containing oil by distillation
IPC: C10G73/06
Filed: 1930-04-28
Abstract: A continuous method of producing low cold test oil from wax-containing mineral oil comprises continously heating the oil in a tubular heater with avoidance of cracking, fractionating the resulting products in a fractionating tower with the aid of reflux to produce a fraction containing all the amorphous wax and sufficiently free from crystalline wax to be dewaxable by methods <PICT:0356172/III/1> <PICT:0356172/III/2> <PICT:0356172/III/3> suitable for the removal of amorphous wax and an adjacent fraction containing wax removable by methods for separating crystalline wax. In the refining of oils that produce an asphaltic residue, the fractionation may be controlled by limiting the cooling of the vapours so as to bring amorphizing substances into the amorphous wax fraction so that the wax may be removable by centrifugal action.  The oil is passed continuously through a tubular still 10, and enters at about 800 DEG  F. through a pipe 24 into a fractionating tower 11 having an auxiliary stripping unit 58.  The tower comprises rectifying sections 17 . . 21 separated by stripping sections 42, 43, 44 and the crude oil is introduced between the lowest trays 17, 18. Vapours pass from the top of the tower through a pipe 29 to a condenser 30 and separator 31 from which water is withdrawn through a pipe 32 while the condensate is passed through a pipe 33 to a tank 34 from which it is recirculated as reflux to the tower through a pipe 37.  The proportions in which the reflux from each rectifying section is passed to the rectifying section below and to the adjacent stripping section are controlled by a weir box 39, Figs. 2 and 3, having a weir 40 across which a dividing plate 41 is moved by a shaft 47 operated by a hand-wheel 49 so as to direct part of the reflux through a spout 50 into a funnel 51 and thence through a pipe 52 to the next rectifying section, while the remainder flows to the stripping section.  Distillates are withdrawn from the stripping zones through pipes 53, 54, 55 and steam may be introduced through a pipe 57 and also into the bottom of the tower through a pipe 56. Residues withdrawn through a pipe 28 are further stripped in a rectifier 58 heated by steam, the vapours evolved being condensed in a condenser 59 and passed to a receiver 60 kept under vacuum by a pump 61, the condensate if rich in amorphizing substances being used to enrich the amorphous containing wax distillate.  Specifications 166,031, 197,389, 201,986, 259,553, and 280,559, [all in Class 91, Oils &c.], are referred to.
