Abstract
Mass transfer packing with a minimal surface or a triply periodic minimal surface which enables significantly improved performance for separation and mixing applications particularly with respect to distillation, liquid-liquid contacting, and heat exchange applications.
Claims20
A method of separating a product gas from a mixed gas stream in a sorption-desorption process which comprises:
- inputting a gas stream into a first side of a mass transfer column such that the gas stream contacts a circulating stream of a liquid sorbent medium in a gas/liquid sorption zone to form a relatively rich solution of a first product gas sorbed in the liquid sorbent medium;
- passing the first product gas sorbed in the liquid sorbent medium in a first flow path in a desorption/regeneration zone comprising a minimal surface area material separating the first flow path from a second flow path in the desorption/regeneration zone, wherein the first flow path and the second flow path pass within a single housing of the desorption/regeneration zone;
- desorbing a second product gas into the second flow path in the desorption/regeneration zone through the first minimal surface area material, forming a relatively lean, regenerated sorbent medium in the first flow path;
- outputting the second product gas from a second side of the mass transfer column, wherein the first and second sides define opposite ends of the mass transfer column;
- and
- passing the relatively lean, regenerated sorbent medium to the gas/liquid sorption zone.

- inputting a gas stream into a first side of a mass transfer column into a gas/liquid sorption zone with a circulating stream of a liquid sorbent medium to form a relatively rich solution of a first product gas sorbed in the liquid sorbent medium;
- passing the first product gas sorbed in the liquid sorbent medium in a first flow path into a first volume of a desorption/regeneration zone, the desorption/regeneration zone comprising the first volume and a second volume that are both enclosed by a single housing;
- forming a relatively lean, regenerated sorbent medium in the first volume;
- desorbing a second product gas in the second volume of the desorption/regeneration zone;
- wherein the first and second volumes are separated by a structure formed by a minimal surface area material preventing liquid mass transfer between the first and second volumes;
- outputting the second product gas from a second side of the mass transfer column, wherein the first and second sides define opposite ends of the mass transfer column;
- and
- passing the relatively lean, regenerated sorbent medium to the gas/liquid sorption zone.
