  • Patent number: 9879517
    Abstract: A modular ‘Subsea Level Gas Separator of Oil Well Effluent’ (SLGOE) about the well-head, precludes gas entrainment reaching the rig. The effluent, past the well-head BOP, through ab oil-diversion tube, enters into ‘gas-separator’ tanks, creating fountain-like up-flow (Sumathi Paturu Up-flow Model). The oil down-streaming into an ‘oil-passage tank’, is ‘styphoned’ to the partitioned collection system, past the diversion tube. Massively clustered top outlets of the tanks let off the ‘instantly’ rising gases. In another embodiment otherwise similarly configured, the oil flows down from the top to the bottom of the tank (Symathi Paturu Down-flow Model). In either model, a gas entrainment instantly reaching the top of the tank(s) is precluded to entrain into the down-streaming oil. Additionally, the immensely pressured gases are attenuated by enormous receptive volume of the tanks and the multiple upstream gas-outlets.

  • Patent number: 6942779
    Abstract: The present invention provides a system and method for selectively removing one or more organic and inorganic and also preferably one or more inorganic contaminants from plating baths. More particularly, the invented method relates to the use of a source of energy in combination with chemical oxidants, alone or in conjunction with a catalyst to oxidize organic contaminants in the plating bath to a level such that the electroplating bath can be recovered and reused after appropriate chemical adjustment. The oxidative treatment method may be a continuous process or a batch process that is performed in a single pass. Residual organics, if desired and chloride ions in the bath are removed from the solution by a chemisorption or physisorption treatment. Inorganic contaminants are removed from the electroplating bath by selective ion exchange resins or electrodialysis, while particulate and suspended colloidal particles are removed by filtration before the treated plating bath is recycled.

  • Patent number: 5160634
    Abstract: A system and method are disclosed for desalinating sea water. The system includes an energy source such as a laser 13, and a container 19 (partly or wholly transparent) for holding the sea water, the sea water having sodium and chlorine ions and a solvent (H.sub.2 O) with a predetermined dielectric value. The system applies a predetermined amount of energy, in the form of a laser beam 35 through the transparent container 19, to the seawater substantially at a resonance frequency of the solvent, for reducing the dielectric value of the solvent and vibrating the ions, permitting them to combine and precipitate out of the seawater, thereby desalinating the seawater. To increase the effect of the beam 35, the system includes a pair of mirrors 15,17 for reflecting the beam back and forth through the sea water.

  • Patent number: 4976861
    Abstract: This invention provides a method for determining the wetting characteristic of a porous medium comprising applying at least one or more drops of each of at least two different liquids having different but closely spaced surface tensions to different locations on the porous medium and if necessary repeating the process until, of two liquids with neighboring surface tension, one is absorbed into the medium, and the other is not.

  • Patent number: 4882072
    Abstract: A method of treating bodies of water such as lakes to correct chemical, biological or other imbalances in the aquatic environment by accurately dispensing a treatment agent into the water in an amount based upon the volume of water being passed over and continuously determined by detection means for the speed of the boat or vessel carrying the dispensing means and the depth of the weater being passed over. When the water is being neutralized by a chemical addition, the pH of the water may also be continuously monitored. A boat particularly designed and adapted for practicing the method is also disclosed. The boat includes a main tank partially supported or floated by the water at least when the tank is loaded and also stabilized and partially or additionally supported by lateral inwardly and outwardly adjustable pontoons when loaded. The boat includes sparging, or mixing, and above or below water dispensing means to dispense the treatment agent.

  • Patent number: 4430230
    Abstract: A method for the removal of liquid or solid impurities from an impurities-containing liquid mixture wherein the impurities immiscible or occasionally miscible with the liquid medium are emulsified or finely suspended in the liquid medium, which comprises kneading the impurities-containing liquid mixture with a viscoelastic material having an affinity with said impurities and having substantially no affinity with said liquid medium, and thereby having the viscoelastic material take up the impurities and separating out the purified liquid medium. According to this method, various liquid wastes can be purified, and noble resources can be recovered from the wastes and re-used, and the separated liquid medium, particularly aqueous medium which is not useful can be thrown away without encountering problems of environmental pollution.

  • Patent number: 4356093
    Abstract: A method of increasing the production or efficiency of a process in which a fluid is passed through a matrix the efficiency of which decreases with use in which the matrix is initially filled at a high rate, and an initial flow rate on the order of not more than three times the final flow rate is employed and subsequently decreased to a final flow rate which is lower than the constant flow rate which would be employed in such a process over a period of time such that the integration of the flow rate with respect to time yields a volume of product greater than or equal to the volume produced at a constant flow rate for such product. The above integrated feed program is described specifically as employed in magnetic separations.

  • Patent number: 4332623
    Abstract: A method for separating a starting fluid containing at least one component which is easy to adsorb and at least one component which is hard to adsorb into the respective components by the use of an adsorption separator which comprises a packed bed where an adsorbent for such components is packed and a fluid passage connecting the front and rear ends of said packed bed so that the fluid is able to be circulated, the method comprising the first step of feeding the starting fluid to an intermediate portion of the packed bed while withdrawing from the separator a fluid rich with either of the components in an amount equal to the feed of the starting fluid from a position downstream of the feed port, the second step of stopping the feed of the fluid to and the withdrawal of the fluid from the separator and moving the fluid remaining in the separator toward the downward direction, and the third step of feeding a desorbent fluid to the separator and simultaneously withdrawing from the separator a fluid rich with eit

  • Patent number: 4243522
    Abstract: Method and apparatus for utilizing the heat content in waste water which has passed through a biological purification plant, the last step of which comprises subjecting the waste water to sedimentation in a settlement tank. A heat pump is provided having an evaporator section which is heated by means of the waste water which has been purified in the settlement tank which is directed to it through a first conduit. During periods in which the flow rate of the waste water through the purification plant is less than the average flow rate which corresponds to the capacity of the heat pump, at least a portion of the waste water which flows through the evaporator of the heat pump is recirculated to the settlement tank, the latter being utilized as a heat reservoir according to the present invention.
