Original Abstract Submitted

unique distillation columns provide improved gas separation. the efficiency of air separation was tested using three different small scale cryogenic distillation columns. an inventive additively-manufactured column demonstrated superior performance as compared to a random packed column and a microchannel distillation (mcd) plate-type layered (ptl) column. these results demonstrate the feasibility of using additive manufacturing to construct mcd devices and pave a way for constructing novel mcd designs. the inventive design features a curved, open channel for vapor transport adjacent a wicking channel for liquid transport that can operate without a siphon under the influence of gravity. operation in an insulated vessel enables separation of components from air.
