Temperature Effect On Salt Dissolution Rate

Five salt samples 20 to 40 cm tall, sealed on all sides except one, were exposed to a series of dissolution tests in various brine solutions and at different temperatures. Solvents were in the 50 to 96% saturation range and the temperatures varied between 40°F and 150°F. The collected dissolution data sets for vertical salt surfaces were analyzed and three were selected to be used for developing a general relation. After various curve fitting efforts, an empirical relation for salt dissolution rate as a function of brine temperature and salinity was developed.
