Abstract

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.
