  • Patent number: 4065294
    Abstract: Chemical waste by products are used in place of conventional heating fuels both for induration and chloridization of impure iron oxide. Pelletized iron oxide is hardened and purified simultaneously by exposure to the heat and combustion products generated from burning chlorinated organic by-products. Hydrogen chloride produced during this combustion reacts with trace metal impurities in the iron oxide to effectively remove substantially all such impurities as volatile metal chlorides. Conventional fuel and binder requirements are substantially reduced or completely eliminated through use of such by-products, while remedying the problem of their disposal.

  • Patent number: 4048053
    Abstract: A process for producing and upgrading carbonaceous tars including adding the carbonaceous material into a first reaction zone of a reactor having at least two reaction zones; adding hot hydrogen to the stream of carbonaceous material to effect a reaction with same to produce reaction products; quenching the mixture while insuring that the total residence time varies from about 2 milliseconds to about 2 seconds; removing at least a portion of the reaction products from the quenched mixture; introducing the residual carbonaceous material into a subsequent reaction zone and repeating the steps for the subsequent reaction zone; and introducing carbonaceous tars produced directly into a fluid coking zone to obtain gas, upgraded coal tars, and hot coke.

  • Patent number: 4041102
    Abstract: An improved process for treating a hydrocarbon stream exiting the hydrocarbon-acid separator of an anionic surfactant promoted, sulfuric acid catalyzed, light olefinisoparaffin alkylation unit wherein the stream contains the alkylate, excess isoparaffins, traces of the acid alkylation catalyst, and an anionic surface-active alkylation promoter. The improvement comprises mixing, prior to introducing into a hydrocarbon-caustic separator, the hydrocarbon stream with a water-caustic solution having at least 15% by wt. concentration of caustic such that the salt of the promoter appears as a flocculent precipitate at the hydrocarbon-water-caustic solution interface in the hydrocarbon-caustic separator.

  • Patent number: 4031007
    Abstract: A conductive interface forms between the oil and water layers in a coalescer apparatus for treating slop oil. The presence of this interface is detected by (a) a capacitance probe and (b) extensions on the coalescer plates. Changes in the feed and discharge rates can then be made, assuring continuous operation.

  • Patent number: 4030549
    Abstract: A subterranean formation is penetrated by a borehole. The formation is fractured and propped with a slurry capable of maintaining a thermit reaction. The slurry is ignited. Upon cooling, a solid metal conductor fin network from the bore into the formation is formed in the fracture system. Energy is transferred between a locus in the borehole and the formation by the network.

  • Patent number: 4029570
    Abstract: An emulsion of crude oil and water that is recovered from an underground reservoir is broken by the addition of a naturally occurring brine to effect separation and recovery of the oil phase of the emulsion. Advantageously, brine taken from the same geologic formation as the crude oil can be used as the emulsion breaker.

  • Patent number: 4027864
    Abstract: A process and apparatus for recovering copper values from acidic solutions containing dissolved copper is disclosed. The process and apparatus comprises reacting in an intake line and feed pump powdered iron in the size range of up to -40 mesh with the solution to displace the copper therefrom as metallic copper, and separating the copper from the solution by settling the metallic copper in the bottom of a vessel known as a polishing tower. Preferably, the solution is clarified by passing it upwardly through a bed of scrap iron, after which the solution is centrifuged to remove particles therefrom.

  • Patent number: 4013543
    Abstract: Crushed carbonaceous fuel is rapidly mixed with hot hydrogen, at 500.degree. to 1,500.degree. C. and 0 to 250 psig., in a reactor, and then, after a short reaction time, rapidly quenched. The total heat-up, reaction, and quench time is less than 2 seconds. This short residence time and rapid heat-up results in a high yield of carbonaceous tars. The carbonaceous tars are subsequently and directly introduced into a fluid coker to obtain gas, upgraded carbonaceous tars, and hot coke.
