134220130 | With inorganic alkaline material treating agent | 8 |
20080276968 | Method of Cleaning a Food Plant - A method of cleaning a food plant of the type which produces an aseptic product or a product with extended shelf life involves at least one circulation with an alkaline detergent solution and at least one circulation with an acidic cleaning solutions. The circulations take place alternatively with the alkaline detergent solution and the acidic cleaning solution. Prior to the first circulation, between each circulation and after the last circulation, rinsings with water take place. Simultaneously with the last circulation with alkaline detergent solution the plant is sterilized, and after the last circulation with the acidic cleaning solution the two last rinsings with water take place with sterile liquid. | 11-13-2008 |
20090107529 | DELIVERY OF FLUID TO MEDICAL DEVICE LUMENS - A method and device provide for delivering fluid for cleaning and/or decontamination to a lumen in a medical device. A tube having a plurality of openings therethrough is inserted into the lumen of the medical device the fluid is flowed through the tube, out of the openings and into the lumen. | 04-30-2009 |
20110259371 | METHODS FOR CLEANING A DRAIN LINE OF A DIALYSIS MACHINE - A method for cleaning a drain line of a dialysis machine downstream of a filtration unit. The method includes closing inlet and outlet valves of the filtration unit, and closing a bypass valve along a bypass line that connects a source line to a drain line. The method also includes configuring the balancing chamber such that flow is permitted only via the drain line, flowing an amount of a cleaning agent into the drain line through a cleaning agent valve, and rinsing the cleaning agent from the drain line with a rinse fluid. | 10-27-2011 |
20120279522 | METHOD AND COMPOSITION FOR REMOVING DEPOSITS - The present invention provides methods and compositions useful for conditioning and removing solid deposits that have formed on or otherwise accumulated within one or more components including, for example, scale formed within a steam generating system. The aqueous cleaning compositions incorporate one or more quaternary ammonium hydroxides characterized by pK | 11-08-2012 |
20140182630 | Heat Exchanger Descaling System Using Blowdown - A system for descaling a heat exchanger utilized in a produced water system of a steam-based thermal hydrocarbon recovery operation is provided. The system comprises a heat exchanger for acting on a produced water; a steam separator in fluid communication with a steam generator for separating steam of a steam quality suitable for injection into a hydrocarbon reservoir and blowdown of a lower steam quality, the blowdown being caustic; and a blowdown loop in fluid communication with the steam separator for collecting the caustic blowdown, the blowdown loop also in fluid communication with the heat exchanger for directing the caustic blowdown through the heat exchanger for descaling the heat exchanger. | 07-03-2014 |
20150368592 | CATALYZED NON-STAINING HIGH ALKALINE CIP CLEANER - A catalyzed highly alkaline cleaning composition for cleaning stainless steel and other surfaces, namely those treated in clean-in-place processes, is disclosed. The composition comprises gluconic acid or salt thereof (e.g. gluconate) to serve as a corrosion and stain inhibitor for the high alkalinity compositions. The composition retains the cleaning and corrosion prevention properties of conventional clean-in-place solutions while being less expensive to produce. | 12-24-2015 |
