  • Patent number: 7204890
    Abstract: Many prior art processes for cleaning predominantly organic hard surfaces have been found to be considerably less effective in removing very fine particles on such surfaces than are the best cleaners for metallic surfaces. However, it has been found, and forms the basis of this invention, that fine particles can be removed effectively from organic surfaces by an indirect process of first forming a thin solid coating over the surface and then removing the solid coating, into which the fine particles that formerly contaminated the surface to be cleaned have presumably become incorporated. Substantially hydrolyzed poly(vinyl acetate) has been found particularly useful for forming the thin solid coating when this coating is to be removed by treatment with an acidic aqueous solution; acrylate polymers are preferred if the solid coating is to be removed by an alkaline aqueous solution.

  • Patent number: 7192527
    Abstract: Processes for removing oil from a solid wellbore material such as drill cuttings or water such as produced by a subterranean formation include contacting the solid material/water with an amino-substituted polymer such as chitosan and a halogenating agent. The oil separates from the solid material and becomes bound within a flocculated solid. The flocculated solid containing the oil subsequently may be combined with a solvent of the amino-substituted polymer. Further, the flocculated solid may be contacted with a reducing agent, converting the flocculated solid back into the amino-substitute polymer and forming an oil-phase separate from the solvent-phase. The oil-phase may then be separated from the solvent phase and recovered. The solvent in which the amino-substituted polymer is dissolved may be recycled for treating more solid material removed from the well bore.

    Abstract: Disclosed is a cleaning agent for heater tubes, which is capable of eliminating deposits such as soot particulates in tubes installed in industrial heaters that typically use oil, coal or gas. The cleaning agent of the present invention is prepared by formulating a chemical composition comprising ammonium nitrate into pellets. Also, the present invention discloses a method of cleaning heater tubes using the cleaning agent. When being utilized for cleaning the heater tubes, the cleaning agent can improve mechanical and chemical cleaning effects, thus shortening of working time and reducing a required amount of the chemical composition, as well as preventing rapid evaporation of the chemical composition, thus increasing cleaning effect. In addition, the cleaning agent can eliminate the cementing effect of sulfur oxides or vanadic oxides in the heater tubes and thus control stably emission of NOx, by selectively containing other additives including magnesium and urea.

    Abstract: A pipe renovating method and system in which a pipe is first cleaned and then coated with a suitable coating material. In the cleaning step, pressurized air and particles of abrasive material are pumped into a first end of a pipe while suction is applied to the second end of the pipe via a vacuum pump to improve flow along the entire length of the pipe. The coating material is subsequently pumped in at one end of the cleaned pipe while suction is applied at the other end. In each step, the suction flow rate is higher than the input flow rate, so as to steer the mixture towards the second end.

  • Patent number: 7011713
    Abstract: The method of continuously collecting jelly compounds from jelly filled cable is performed by recycling operation of a solvent by repeatedly heating, cleaning and condensing the recycling solvent used to deprive the jelly compounds of the jelly filled cable. The solvent can be retrieved for reuse unlimited times, and the collected jelly compounds can be purified for reuse too. The method is energy saving with less consumption of solvent. Absolutely no worry of an additional public nuisance.

  • Patent number: 7008528
    Abstract: A process for continuously extracting oil from a solid or liquid oil-bearing material comprises (a) removing air from the extraction system, (b) introducing an inert gas into the extraction system at a pressure sufficient to maintain a normally gaseous solvent in liquid state, (c) introducing an oil-bearing material into a silo, (d) passing the oil-bearing material from the to a jet pump mixing device, (e) introducing a liquified normally gaseous solvent into the jet pump mixing device, (f) mixing the oil-bearing material and the solvent in the jet pump mixing device for a time sufficient to permit complete wetting of oil-bearing material by the solvent to form a mixture, (g) heating the mixture to near supercritical conditions; (h) passing the mixture through an extractor having a screw conveyor adapted to rotate at a first rpm range and a centrifugal drum adapted to rotate at a second rpm range, (i) treating the mixture within the extractor in such a manner that supercritical temperature and pressure are at
