Lewis, R. O.

Several promising countermeasure methods for maintaining heat transfer efficiency in OTEC heat exchangers have been evaluated by the LaQue Center for Corrosion Technology, Inc., under contract to Argonne National Laboratory (ANL). Heat transfer monitors designed at Carnegie-Mellon and modified by ANL were utilized to evaluate the effectiveness of several countermeasure methods for candidate OTEC heat exchanger tubing. Countermeasure methods evaluated included the use of abrasive slurries, Amertap sponge rubber balls (alone and in combination with continuous and intermittent chlorination), M.A.N. brush, surfactant/dispersant organic chemical cleaning and continuous and intermittent chlorination.
