Flow-Sheet Design for an Innovative SANEX Process Using TODGA and SO3-Ph-BTP

An innovative SANEX process was designed using an organic phase comprising TODGA in TPH + 5% 1-octanol and an aqueous phase containing SO3-Ph-BTP for the selective strip. The flow-sheet was optimized using batch data, single stage data and data from previously run TODGA processes. Recoveries for some key elements were calculated for selective strip section of the process using the SX Process program. According to the calculations, the An(III) are recovered from the PUREX raffinate with insignificant amounts of impurities. The presented flow-sheet will be used for a centrifugal contactor demonstration process which is expected to be successful.
