Miniature DIAMEX processes in a hollow fibre module micro-plant: process development and optimisation

摘要

A hollow fibre module (HFM) micro-plant was built to per-form continuous liquid-liquid extraction tests with very small feed volumes, using miniature HFM as phase contactors. Spiked DIAMEX tests (i.e., co-extraction of americium, curium, and lanthanides from PUREX raffinate) were performed in this plant. Following some flow sheet modifications, raffinate decontamination factors of up to 30000 and 900 were achieved for americium and curium, respectively.
