Abstract:
A method for removing particulate contaminants from a fluid stream, the method comprising:supplying a liquid fluid stream to at least one first centrifugal cleaner, the liquid fluid stream including a liquid carrier fluid and particulate contaminants;removing particulate contaminants from the liquid fluid stream having a specific gravity of at least about 0.0001 different from the specific gravity of the liquid carrier fluid;adjusting the temperature of the liquid fluid stream leaving the cleaner by an amount effective to provide particulate contaminants remaining in the liquid fluid stream with a specific gravity of at least about 0.0001 different from the specific gravity of the liquid carrier fluid; andremoving particulate contaminants having a specific gravity of at least about 0.0001 different from the specific gravity of the liquid carrier fluid.
