Abstract: The present invention comprises a method and system for the in-situ cleaning of a heat exchanger tube bundle of carbonaceous deposits. Using the method and system, an organic solvent is brought into fluid communication with one or more heat exchanger tube bundles in a closed system. The closed system is formed at the site of operation of the heat exchanger tube bundles and without having to remove the heat exchanger tube bundles from their shells or other associated equipment. Once the closed system is formed, the organic solvent is brought to a temperature at which it is effective to remove carbonaceous deposits from the heat exchanger tube bundle and flowed through the equipment associated with the heat exchanger tube bundles so as to contact the heat exchanger tube bundles and remove carbonaceous deposits that have formed therein.

Abstract: It is surprisingly found that when diamond particles are embedded into an alcohol wipe, the cleansing wipe that is formed is extremely useful at cleaning diamond jewellery in the home. It is also surprising that, given the abrasive nature of diamond, the diamond particles result in a satisfactory clean without causing any damage to the surface of the diamond being cleaned. The final result is that the cleaned diamond has recovered most of its original fire, life and brilliance.
