Abstract: An apparatus in which a downflowing high pressure stream of hot raw synthesis gas from the reaction zone of a free flow partial oxidation gas generator at a temperature in the range of about 1800.degree. to 3000.degree. F. is passed through a first gas diversion and residue separation chamber contained in a first pressure vessel where the velocity of the gas stream is reduced, solid material and molten slag are separated by gravity from the gas stream, and the direction is diverted into a thermally insulated side transfer line. The hot gas stream is then passed through a thermally insulated gas-solids impingement separation means contained in a second pressure vessel where its direction and velocity is changed and additional residue is separated. The hot gas stream is then passed upwardly through a radiant cooler where additional solid matter is removed by gravity and the gas temperature is reduced to a temperature in the range of about 900.degree. to 1800.degree. F.

Abstract: An ignition burner and a pilot burner form part of an ignition system for a fluidized stream of finely-divided coal particles in a pressurized gasifier housing having a slag overflow pipe coupled to a discharge vessel. A fuel supply pipe delivers fuel for combustion by the ignition burner and the pilot burner. A sparkplug or hot wire is used to ignite the fuel delivered to the ignition burner. The flame produced by the ignition burner is widened by a baffle so that ignition by the pilot burner occurs to produce a flame which is monitored through a thermocouple. The parts forming the ignition system are carried by a pair of levers with pivots on the inner wall of a slag overflow pipe for movement between an operative position wherein the ignition burner is situated near the slag-receiving opening of the overflow pipe and an inoperative position wherein the ignition burner is protected from contact by slag and radiation heating.

Abstract: In a dry seal gasholder cylindrical storage tank with a vertically-movable piston, an improved piston leveling system includes a vertically-movable weight outside the tank and connected by equal-length cables to spaced-apart support points on the piston at different distances from the weight. An array of guide sheaves on the tank define equal-length cable paths. The cables are pivotally coupled to spaced-apart points on a coupling plate to which a pair of attachment plates on the weight are also pivotally connected. Apertures in the attachment plates and the coupling plate are disposable in registry with one another for receiving a pin therethrough when the cable attachment points are in horizontal alignment, thereby to indicate equal tension in the cables.

Abstract: Process for converting a relatively high boiling point crude oil fraction, such as a 500.degree.+F. initial boiling point topped crude to synthetic natural gas. In the process, a lower boiling point fraction of the feedstock is hydrogasified while a residual oil fraction of the feedstock is partially oxidized to produce hydrogen for use in the process. A mid-cut fraction between the gasification fraction and the partial oxidation fraction is converted in a combined steam reforming-methanation stage, along with some by-product aromatics, to produce additional synthetic natural gas products.

Abstract: A relative heavy immiscible fluid is used with water or a relatively light treating fluid in a treating tank under ultrasonic vibrating conditions and objects to be treated are immersed in the treating fluid.

Abstract: Methane is produced from peat by solubilizing the phenolic polymers therein, and oxidizing the solute to produce short chain molecules. The short chain molecules are fermented to produce a gas that this scrubbed to remove CO.sub.2 to produce methane. Solubilizing takes place in a vertically oriented pressurized vessel that is circular in cross-section and divided into a number of regular vertically elongated compartments, each comprising a circular sector in cross-section, and extending the majority the height of the vessel. Slurried peat is fed into the top of one compartment while another compartment is being emptied from the bottom, the compartment being filled or emptied being progressively changed in response to rotation of a central shaft in the vessel. Oxidation of solubilized peat takes place in a structure that transports the solubilized peat in a substantially vertical wave path from an inlet to an outlet with oxygen being introduced at the bottoms of segments of the wave path, and CO.sub.

Abstract: A process for forming charging fuel into agglomerates for the pressure gasification of coal, comprises the steps of mixing fine, granular charging fuel with a binder outside the pressure reactor, subjecting the mixture, in a pressure vessel, to the pressure prevailing in the reactor, and feeding agglomerates produced from the mixture to the fixed bed of the reactor from above. The mixture is made with a binder which hardens when heated and is kept below hardening temperature during subsequent subjection to pressure until fed to the reactor, the agglomerates being produced by hardening of the binder in the heat prevailing in the reactor above the fixed bed.
