Experimental design of tritium extraction loop from lead lithium eutectic

The engineering sizing of the packed desorption column of hydrogen isotopes from Pb–17Li eutectic alloy. A rate based model using experimental mass transfer coefficients from a Melodie loop

“…Mohan et al [2] presented a model of packed columns design for tritium desorption based on the HTU concept. Plug flow is applied and mass transfer resistances are considered in both phases.…”
