ABSTRACT:
A cryogenic liquid is used to directly or indirectly cool solid or liquid contaminants adhering to apparatus surfaces to effect a change in the physical characteristics of the contaminants and thereby render them more susceptible to removal operations. The direct technique contemplates providing a source of liquid cryogen, contacting the liquid cryogen from the source thereof directly with the contaminated surfaces of the apparatus to effect at least a partial bonding separation from the apparatus surface, and effectively removing the contaminant material, while the indirect technique contemplates utilizing an existing system for circulating heated fluid within the apparatus by preventing the flow of hot fluid into the existing conduit channels, selectively and removably coupling adjacent conduit channels to effect a change of flow from a series flow pattern to a parallel flow pattern, permitting cryogenic liquid to flow into the conduit channels, allowing cryogenic liquid to circulate therein for a predetermined period of time to effect a manageable property change of the contaminant material, and removing the contaminant material therefrom.
