A vapor extraction apparatus includes a gel sorbent capable of absorbing vapor directly into the liquid state and capable of disgorging the absorbed liquid in a phase-transition. The apparatus includes a housing adapted for movement from a first position, where it is exposed to a vapor-containing gas stream and a first environmental condition, and capable of moving to a second position, where it is exposed to a second environmental condition. A gel sorbent is disposed on at least one surface of the housing. The gel sorbs vapor from the gas stream as liquid when the sorbent is in its first position. The sorbent disgorges the liquid during phase-transition collapse when it is in the second position. A method of extracting vapor from a process gas stream includes contacting a phase transition gel sorbent with vapor under conditions sufficient for the gel sorbent to undergo a phase transition and absorb vapor as liquid inside the gel sorbent. The gel sorbent is then exposed to conditions sufficient for it to undergo a phase transition and disgorge the liquid from inside the gel sorbent. The disgorged liquid is removed from the gel sorbent.

Gel-based vapor extractor and methods

A transverse flow, self-heating electrically conductive sorption system for separating species of different adsorption characteristics in a fluid includes a containment vessel, an electrically conductive permeable sorbent bed having a multiplicity of adsorption sites in said vessel; a porting structure for supplying contaminated fluid in a first direction at one surface of the bed and for receiving the contaminated fluid at another surface of the bed; and a pair of spaced electrodes for applying current through the bed in a second direction transverse to the first direction to self-heat the electrically conductive sorbent bed.

Transverse flow self-heating electrically conductive sorption system

An electrically conductive sorption and in situ regeneration system and method for separating species of different adsorption characteristics in a fluid includes flowing a contaminated fluid through an electrically conductive sorbent bed having a multiplicity of adsorption sites, and providing an electric current through the sorbent bed to heat the bed to increase the adsorption sites available for adsorption by the bed of the more strongly adsorbed specie by inhibiting adsorption by the bed of the less strongly adsorbed specie which might occupy adsorption sites in the bed.

Electrically conductive sorption system and method

This invention relates in general to the preparation of near zero CTE (coefficient of thermal expansion) film-based structural components from aromatic heterocyclic, molecularly oriented, or lyotropic liquid crystalline, polymers, and to the use of such near-zero CTE film based structural components for the preparation of space-based structural members, especially film-based components used in the construction of satellites, space craft, space stations, space-based mirrors, e.g., for the Strategic Defense Initiative, and the like.
