Abstract:

In a study of fouling of heat exchangers, aqueous solutions of CaSO4 (calcium sulfate) and Li2SO4 (lithium sulfate) were circulated through electrically heated tubes at controlled conditions. Measured induction periods and fouling rates of both salts were found to be primarily functions of the supersaturation of the solutions. Secondary correlating parameters were surface temperature for the Li2SO4 solutions and mass transfer coefficients for the CaSO4 solutions.
