Title: Products and processes for treating wells
Inventor: SLUDER JERALD LEWIS
IPC: E21B33/138
Filed: 1965-10-09
Abstract: A composition for treating wells is produced by preparing an epoxy-containing polymerizable mixture and rapidly coating the mixture onto particulate solids. the coating being completed in a time not substantially greater than five minutes after the mixture is prepared, to maintain the mixture at a temperature not significantly above the ambient temperature.  The mixture may p  contain a hardener and/or an accelerator.  The amount of the mixture may be from 6 to 30 per cent by weight of the solids.  The particle size may be in the range of from 10 to 100 mesh (U.S.S.). The solids may be organic e.g. coconut, walnut or ground nutshells, polymeric materials e.g. phenol-formaldehyde melamine, furfural, and furfuryl resins, or inorganic e.g. coke, slag, sand. The coated solids may subsequently be slurried in a vehicle in which the mixture is substantially insoluble.  Fluid-producing wells are treated by introducing a slurry of the composition in a vehicle e.g. a liquid hydrocarbon which may be substantially free from aromatic hydrocarbons, through the well into a fluid-bearing stratum.  A well treatment agent comprises a slurry of the composition in an aqueous or non aqueous vehicle in which the mixture is substantially insoluble e.g. crude oil.  The concentration of coated particles in the vehicle may be from 0.25 to 10.0 pounds per U.S. gallon.  The vehicle may be a hydrocarbon which may be substantially free from aromatic hydrocarbons.  One or more fluids may be injected into the well before or after the slurry. The well can be back flushed or a slurry of uncoated particulate material, either the same or different from the coated particulate material, may be introduced before or after the slurry of coated particles.

Filed: 1974-10-09
Abstract: 1464638 Gas purification; particulates E I DU PONT DE NEMOURS & CO 9 Oct 1974 [10 Oct 1973] 43786/74 Heading C1A Hot gas streams are purified by (a) cooling the gas to a temperature above the dew point in an evaporative cooler, (b) separating the dry particulates in a dry collection means, (c) feeding the gas stream into a scrubber wherein it is contacted with an aqueous solution or slurry which absorbs acidic or basic components and (d), removing the scrubbed gas stream from the scrubber, and passing the scrubbing solution or slurry to the evaporative cooler of step (a), where it serves to cool the incoming gas stream whilst simultaneously being evaporated to dryness; as the pH of the scrubbing solution is adjusted prior to step (d) by addition of sufficient of a salt forming chemical to form a salt with the absorbed acids or bases in the solution, evaporation of this scrubbing solution yields a dry, solid salt, which is collected in the dry collection means of step (b). In the embodiment shown in Fig. 1, the hot gas 1 enters the evaporative cooler 2, wherein it is cooled to 250-1000‹ F. by contact with the purge 3 from the scrubber 4. Solid salt residues produced by evaporation of the scrubbing solution and solid particulates originally in the hot gas are removed in the dry collection means 6 (e.g. a baghouse containing bag filters, electrostatic precipitators, cyclones or packed beds), the solids being removed as stream 19. The particulate free gas 7 is passed to scrubber 4, wherein water soluble acidic or basic gases are removed by contact with aqueous scrubbing solutions or slurries which may contain either acids or bases which react with basic or acidic impurities respectively to form salts which may or may not be watersoluble. The scrubbed off gas leaves the system via 10, but may be further processed for SO 2  removal via the embodiment of Fig. 2 (not shown). The scrubbing solution which now contains a dissolved or suspended salt is then used to cool the incoming hot gases in the evaporative cooler 2.

Abstract: 1,199,724. Extruding sheets; composite films; fibrillated products. O.-B. RASMUSSEN. 31 Oct., 1967 [5 Oct., 1966], No. 44525/66. Headings B5A and B5B. [Also in Division Dl] A sheet-like extrusion product consists of transverse lamellae 43 of a first polymeric material and longitudinal lamellµ 45 of a second polymeric material, the lamella 45 being restricted to the surface region of the sheet. If desired a third polymeric material 44, which may be foamed, is introduced into the interstices between lamellµ 43 and 45. The sheet can be used as a substitute for a non-woven fabric by fibrillating the lamellµ 45 either by drawing the sheet or by using a two-component compound for the second material one of which components can be dissolved out. Apparatus suitable for producing the above sheet material comprises a fixed extruder head provided with a row of slots, slots 9 being fed via channels 6 and 8 with the first polymeric material, whilst slots 11 are fed via channel 7 with the third polymeric material. Located in front of the slots is a transversely reciprocable frame made up of a pair of combs 12 having oppositely directed teeth 15 and 16, each of which is provided with a slot 17 through which the second polymeric material is extruded. The composite sheet passes through the combs and is taken off by ' conventional means. In a second embodiment, see Fig. 3 (not shown), the set-up is similar to that above except that each comb carries a double row of teeth, the teeth in the row furthest from the slots 9 and 11 being aligned with the spaces between the teeth in the row nearest said slots. In a third embodiment in which a tube is formed (see Fig. 4, not shown) the slots 9 and 11 are located in a circle whilst the teeth are carried by annular combs rotatable or oscillatable relative to the slots. In a first example the first polymeric material is nylon, the third polythene, and the second a mixture of polythene and nylon. After extrusion and drawing the polythene is washed out to leave a fabric having the characteristics of a woven textile. The components of the second material may be derived from sources separate from those for the first and third materials or may be tapped from those sources. In another example the third material may be foamed polythene or foamed polystyrene.
