Abstract
Abstract The conformation of the apparatus is broadly that of a shell-and-tube heat exchanger that can be of the single pass or multipass variety, and it can have substantially straight or bent tubes, including tubes with return bends. However, in this apparatus tubes are electrodes, and they are microporous. Electrode means of polarity opposite the tubes are provided; e.g., in the form of one or more charged heads or elements between such head or heads and the tube ends proximate thereto. Preferably the counter electrodes actually extend into the tubes. Appropriate fluid inlets and outlets and electrical terminals are provided.
