  • Patent number: 11524314
    Abstract: In a second liquid supply step, a second liquid film and a first liquid film surrounding a side of the second liquid film are formed on an upper surface of a substrate. Then, in a vapor layer formation step, by heating the substrate, a second vapor layer is formed by evaporating the second liquid contacting the upper surface of the substrate, and the second liquid film is held on the second vapor layer. Since the second liquid included in the second liquid film has a high vapor pressure, a height position of a lower surface of the floating second liquid film may be kept high. By blowing a gas to the floating second liquid film, a hole is formed in the second liquid film, and by expanding the hole toward an outer periphery of the substrate, the first liquid and the second liquid are removed outside the substrate.

The reaction of the alkali salts of chlorite and chlorate and acid produces chlorine dioxide in-situ in the water of the industrial water system. The chlorine dioxide kills microorganisms and the acid acts to remove deposits upon the water-contact surfaces of the equipment. This cleaning and disinfecting method works in a variety of industrial water systems including cooling water systems.

  • Patent number: 8664172
    Abstract: A self-sticking disintegrating cleansing block to be attached directly to a wall of a toilet bowl or urinal, above the water-line and in the stream of flush water, by pressing the cleansing block to the wall. The cleaning block includes 25% to 99% of a solid surfactant, and 1% to 25% of a liquid component. The cleansing block may include a substrate removably attached to a surface of the cleansing block. In use, the substrate is removed from the cleansing block and the exposed surface of the cleansing block is pressed to a surface in a position above any waterline that is contacted by a rinse liquid that disintegrates the cleansing block. Rinse liquid is then allowed to contact the cleansing block such that an amount of the cleansing block is mixed with rinse fluid to clean the surface or a liquid reservoir adjacent the surface.

  • Publication number: 20130333729
    Abstract: Disclosed is a dry cleaning method for removing a composition represented by a compositional formula of MgaZnbOHc (0?a?1, 0?b?1, 0?c?1, and 0.5?a+b?1), which accumulates in a film formation chamber or in an exhaust pipe of an apparatus for forming a composition represented by a compositional formula of MgXZn1?XO (0?x?1) into a film, by using a cleaning gas. This method is characterized by that a cleaning gas containing ?-diketone is used and that the composition is removed by reacting the composition accumulated with the cleaning gas at a temperature of from 100° C. to 400° C. It is possible by this method to remove the composition without opening the apparatus.

  • Patent number: 8609399
    Abstract: The present inventors have surprisingly discovered that phytic acid tenaciously precipitates with soluble metals in food or fuel ethanol-processing fluid, producing insoluble organometallic salt deposit or scale on the processing equipment that must be removed in order to facilitate further ethanol processing. The present invention relates to converting phytic acid salts or phytates to inorganic phosphates to improve metal solubility and reduce deposition within processing equipment.
