Heat and Mass Transfer Study to Understand Thermal-Cycling Absorption Process (TCAP) Scale-Up Issues

TCAP was invented by SRNL and is a world-leading technology in hydrogen isotope separation, a critical process for fusion energy development and scientific research. External interests inquiries have been received for as high as a 1000-fold throughput increase over the currently available TCAP system. This study determined a major factor impacting TCAP column scale-up. A model derived by J. Calvin Giddings indicates that the combination of a coiled packed column and an increase in the column tube radius results in reduction of column separative performance. Reevaluation of data from SRNL TCAP column testing performed in 2004 indicates that the results are consistent with the Giddings model. Work with the Auburn University Center for Microfibrous Materials Manufacturing indicates that microfibrous entrapped sorbents (MFES) made from copper microfibers and Pd K could resolve issues with channeling and improve heat transfer and cycle time in TCAP columns.
