Abstract: The present invention relates to a heat exchanger. The heat exchanger includes: a heat exchanger cartridge and a heat exchanger shell. The heat exchanger cartridge includes: a first end with a water inlet and outlet; a second closed end; a plurality of tubes that extend between the first end and the second end; and a plurality of baffles attached to one or more of the tubes. The heat exchanger shell includes: a hollow body with a first end having an opening for receiving the heat exchanger cartridge, and a second closed end; a hypochlorite inlet positioned at the first end; and a hypochlorite outlet positioned at the second end. The plurality of tubes can each independently have a length within a range of from 37 and 80 inches, and an inner diameter within a range of from 0.170 inches and 0.190 inches.

Abstract: The present invention relates to a gas process system for treating a solids-containing and/or solids-forming gas stream, wherein said gas process system comprises a device for forming a liquid film between the gas stream to be treated and an interior wall of such gas processing system, and wherein such liquid film is spaced apart from the interior wall by a distance that is sufficient to prevent solids from passing through such liquid film to form deposition on the interior wall.
