Abstract

Methods for adjustable separation of solutes and solvents involve the combination of the use of a maximally swollen membrane and subsequent vacuum depressurization exerted on the permeate side of that membrane. By adjusting the extent of depressurization it is possible to separate solvent from solutes and solutes from each other. Improved control of separation parameters as well as improved flux rates characterize the present invention.

Membranes, methods of making membranes, and methods of separating gases using membranes

Patent Ho, W. S. Winston

Membranes, methods of making membranes, and methods of separating gases using membranes are provided. The membranes can include at least one hydrophilic polymer, at least one cross-linking agent, at least one base, and at least one amino compound. The methods of separating gases using membranes can include contacting a gas stream containing at least one of CO.sub.2, H.sub.2S, and HCl with one side of a nonporous and at least one of CO.sub.2, H.sub.2S, and HCl selectively permeable membrane such that at least one of CO.sub.2, H.sub.2S, and HCl is selectively transported through the membrane.

Preparation of aligned nanotube membranes for water and gas separation applications

Patent Lulevich, Valentin; Bakajin, Olgica; Klare, Jennifer E.; ...

Fabrication methods for selective membranes that include aligned nanotubes can advantageously include a mechanical polishing step. The nanotubes have their ends closed off during the step of infiltrating a polymer precursor around the nanotubes. This prevents polymer precursor from flowing into the nanotubes. The polishing step is performed after the polymer matrix is formed, and can open up the ends of the nanotubes.

Modified zeolite Y membranes for high-performance CO₂ separation

Patent Shqau, Krenar; White, Jeremy C.; Dutta, Prabir K.; ...

Supported zeolite Y membranes exhibiting exceptionally high CO2 selectivities when used in CO2/N2 gas separations are produced by a seeding/secondary (hypothermal) growth approach in which a structure directing agent such as tetramethylammonium hydroxide is included in the aqueous crystal-growing composition used for membrane formation.

Use of exhaust gas as sweep flow to enhance air separation membrane performance

Patent Dutart, Charles H [Washington, IL]; Choi, Cathy Y [Morton, IL]

An intake air separation system for an internal combustion engine is provided with purge gas or sweep flow on the permeate side of separation membranes in the air separation device. Exhaust gas from the engine is used as a purge gas flow, to increase oxygen flux in the separation device without increasing the nitrogen flux.
