Title: Separation of asphalt-type bituminous materials
IPC: C10C3/08
Filed: 1954-08-27
Abstract: 774,597. Treating asphalt. KERR-McGEE OIL INDUSTRIES, Inc. Aug. 27, 1954 [Aug. 28, 1953], No. 24914/54. Class 22. Asphalt-type bituminous materials are separated into at least two fractions by treating each volume with at least two volumes of a C4-8 hydrocarbon solvent at a temperature between 175‹F. and 50‹F. below the critical temperature of the solvent, and at a pressure at least equal to the vapour pressure of the solvent at the temperature selected, and separating the resultant fractions while in the liquid state. Specified solvents are n-butane, n-pentane, n-hexane, n-heptane, iso-pentane, iso-octane and mixtures thereof. In an example n-pentane at 250‹F. flows from a container 10 to be mixed at 14 with asphalt at 300‹F. from a reservoir 16, and the mixture passed to an equilibrium vessel 20 at 250‹F. and 525 p.s.i.g. wherein the asphaltive phase and solution of petrolenes separate completely from each other. After separation the asphaltine passes downwardly to a storage tank 24, with or without heating to 500‹F. to separate off any remaining solvent which may be recycled. The petrolene solution is removed via line 26 and passed through heat exchangers 34, 36, arranged in series, whereby the temperature is raised to 382‹F., whereupon it enters a second equilibrium vessel 40 in which the resin phase separates completely from the oil solution. The resin phase is passed to a storage vessel 44 whilst the oil solution is withdrawn via line 46, passed through a heat exchanger 48 to raise its temperature to 420‹F. and finally passed to a third equilibrium vessel 50 wherein the oils separate from the pentane solvent, and pass to a storage vessel 54. The pentane is withdrawn through line 56 and passes through heat exchangers 34, 36 and also a water-cooled heat exchanger 58 whereby its temperature is reduced to 250‹F. and is then passed to storage tank 10 at that temperature.

Title: Improvements in regulating and controlling the position of apparatus and mechanism according to fluid pressure, applicable to furnace plants
IPC: G05D16/06
Filed: 1920-09-07
Abstract: 172,415. Hopwood, J. M. Sept. 7, 1920. Valves controlled by pilot or relay valves.- Comprises a method of controlling a valve by fluid pressure, wherein a variable high pressure applied to a movable member is partially neutralized by a constant pressure, the remaining small variable pressure moving the member being balanced by variation in the area of contact of the member with a flexible member to which a constant fluid pressure is applied. In the form shown in Fig. 2, a variable high pressure, as from a steam boiler is admitted to a chamber 3 closed by a flexible diaphragm 4. The bulk of the normal total pressure acting on the diaphragm is balanced by a weight hung from a lever 7 pivoted at 8 and bearing on a knife edge 6 secured to the diaphragm. A disc 2 sliding in the chamber 10 bears on the lever 7 through the medium of a strut 9 and has loosely resting upon it a flexible diaphragm upon which acts a small uniform pressure. This is supplied by forcing air through the valve 14 into an inverted cup 13 in a shell 12 filled with suitable liqui'd. If the pressure in the boiler rises above normal, the part 2 is moved upwards and consequently the area of contact between the disc 2 and the diaphragm increases, the disc 2 thus taking an additional proportion of the pressure acting on the diaphragm 1 until the increase in the boiler pressure is balanced. During this variation, the lever 7 moves and the movement is used to control a valve. In modifications, the diaphragm may be replaced by a rubber ball or by a cylinder, with a spherical end made of flexible material which bears on the disc 2. Specification 141,137, [Class 51 (i), Furnaces and kilns, Combustion apparatus of], is referred to.
