Title: Methods for the separation of CO2 from a gas stream

Abstract

Disclosed herein are 2-stage membrane separation methods for capturing CO2 from a feed gas. The methods can employ two selectively permeable membranes, which may be the same or different. The selectively permeable membrane can have a carbon dioxide permeance of from 500 to 3000 GPU at 57° C. and 1 atm feed pressure and a carbon dioxide:nitrogen selectivity of from 10 to 1000 at 57° C. and 1 atm feed pressure. High pressure ratios across the membranes can be achieved by compressing the feed gas to a high pressure, by using vacuum pumps to create a lowered pressure on the permeate side of the membrane, by using a sweep stream, or a combination thereof. When a sweep stream is used, the sweep stream may include a portion of the retentate gas stream obtained from the retentate side of one or more of the membranes used.

Thermophoretic separation of aerosol particles from a sampled gas stream

Patent Postma, Arlin K.

A method for separating gaseous samples from a contained atmosphere that includes aerosol particles uses the step of repelling particles from a gas permeable surface or membrane by heating the surface to a temperature greater than that of the surrounding atmosphere. The resulting thermophoretic forces maintain the gas permeable surface clear of aerosol particles. The disclosed apparatus utilizes a downwardly facing heated plate of gas permeable material to combine thermophoretic repulsion and gravity forces to prevent particles of any size from contacting the separating plate surfaces.

Two-phase separator device for removing condensate or particulate from a gas stream

Patent Cognata, Thomas; Zimmerman, Brittany Lynn

This disclosure provides a two-phase separator device for separating condensate or particulate from a gas stream. In some implementations, the separator device removes water from air and may operate under micro-gravity conditions. The gas stream flows through the two-phase separator device and passes through a rotatable vane assembly along a flow path without being redirected in another flow path. Condensate or particulate in the gas stream is impacted by a plurality of vanes of the rotatable vane assembly, and the condensate is captured by features formed within the plurality of vanes. The captured condensate is accelerated radially outwardly along themore » « less

Method for separating water soluble organics from a process stream by aqueous biphasic extraction

Patent Chaiko, David J [Naperville, IL]; Mego, William A [Naperville, IL]

A method for separating water-miscible organic species from a process stream by aqueous biphasic extraction is provided. An aqueous biphase system is generated by contacting a process stream comprised of water, salt, and organic species with an aqueous polymer solution. The organic species transfer from the salt-rich phase to the polymer-rich phase, and the phases are separated. Next, the polymer is recovered from the loaded polymer phase by selectively extracting the polymer into an organic phase at an elevated temperature, while the organic species remain in a substantially salt-free aqueous solution. Alternatively, the polymer is recovered from the loaded polymermore » « less
