{open_quotes}Open vessel{close_quotes} heat balance for TBP-nitric acid solutions
- Westinghouse Savannah River Company, Aiken, SC (United States)
Heat balances were performed for both single phase (organic) and two phase (organic and aqueous) TBP/HNO{sub 3} solutions at temperatures above 100{degrees}C. The balance included the heat produced from oxidation minus losses from evaporation and butylnitrate formation by esterification. Net heat measurements were performed using an isothermal calorimeter. Losses from evaporation were determined from the volume of condensate produced (ice bath trap) and the component concentrate Carbon and nitrogen balances were performed to determine the stoichiometry of the reaction. The heat from oxidation was then calculated using the heats of formation of the reactants and products. Balances were obtained assuming that the heat from esterification was near zero (negligibly small). For two layered reaction systems the net heat was maintained endothermic, and constant with time, due to the transport of water to the organic phase by bubble mixing at the interface. This transported was replaced the water lost in the organic phase by evaporation.
