Abstract
A permeable microcapsule embedded fabric acts as a sorbent that creates mold-able, variable geometry fabrics for static or dynamic use. The fabric is composed of micro encapsulated solvent spheres held together by structural members. The fabric provides an excellent means to absorb and separate gases and/or liquids, particularly to separate carbon dioxide from flue gases.
Claims22
A fabric for removing carbon dioxide from a gas containing the carbon dioxide, comprising:
- a web of support material;
- spherical capsules contained in said web;
- a polymer surface layer on said spherical capsules, wherein said polymer surface layer is permeable to carbon dioxide;
- and
- stripping solvents encapsulated within said polymer surface layer of said spherical capsules, wherein said polymer surface layer absorbs the carbon dioxide.
A method of making a fabric for removing carbon dioxide from a gas containing the carbon dioxide, comprising:
- providing spherical capsules;
- providing a polymer surface layer on said spherical capsules, wherein said polymer surface layer is permeable to carbon dioxide;
- providing stripping solvents encapsulated within said polymer surface layer of said spherical capsules, wherein said polymer surface layer absorbs the carbon dioxide;
- and
- connecting said spherical capsules with a web of support material to make the fabric.
A method of removing carbon dioxide from a gas mixture containing the carbon dioxide, comprising the steps of:
- providing spherical capsules;
- providing a polymer surface layer on said spherical capsules, wherein said polymer surface layer is permeable to carbon dioxide;
- providing stripping solvents encapsulated within said polymer surface layer of said spherical capsules, wherein said polymer surface layer absorbs the carbon dioxide;
