Patent number: 12128358Abstract: A method of treating a fluid comprises introducing a feed fluid stream comprising multiple materials to first side of a semi-permeable membrane. A draw fluid stream having a higher temperature than the feed fluid stream is introduced to second, opposing side of the semi-permeable membrane to form a thermal gradient across the semi-permeable membrane. One or more of the multiple materials of the feed fluid stream is drawn through the semi-permeable membrane and into the draw fluid stream via thermal gradient osmosis. A fluid treatment system and a thermal gradient osmosis apparatus are also described.Type: GrantFiled: September 1, 2020Date of Patent: October 29, 2024Assignee: Battelle Energy Alliance, LLCInventors: Aaron D.

Patent number: 11261111Abstract: A method of treating an aqueous solution comprises forming a treatment stream comprising a condensable material. The treatment stream is introduced to an aqueous solution comprising water and a solute to fractionally precipitate the solute out of the aqueous solution and form a solids stream comprising the solute and an aqueous liquid stream comprising at least one solute-depleted solution of the water and the condensable material. The condensable material of at least a portion of the aqueous liquid stream is separated from the water of the at least a portion of the aqueous liquid stream to at least partially reform the treatment stream and form an aqueous liquid product stream depleted in the solute.

Patent number: 9080052Abstract: Stable, high performance polymer compositions including polybenzimidazole (PBI) and a melamine-formaldehyde polymer, such as methylated, poly(melamine-co-formaldehyde), for forming structures such as films, fibers and bulky structures. The polymer compositions may be formed by combining polybenzimidazole with the melamine-formaldehyde polymer to form a precursor. The polybenzimidazole may be reacted and/or intertwined with the melamine-formaldehyde polymer to form the polymer composition. For example, a stable, free-standing film having a thickness of, for example, between about 5 ?m and about 30 ?m may be formed from the polymer composition. Such films may be used as gas separation membranes and may be submerged into water for extended periods without crazing and cracking. The polymer composition may also be used as a coating on substrates, such as metal and ceramics, or may be used for spinning fibers. Precursors for forming such polymer compositions are also disclosed.Type: GrantFiled: August 30, 2013Date of Patent: July 14, 2015Assignee: Battelle Energy Alliance, LLCInventors: John R.

Patent number: 8129498Abstract: A PBI compound includes imidazole nitrogens at least a portion of which are substituted with a moiety containing a carbonyl group, the substituted imidazole nitrogens being bonded to carbon of the carbonyl group. At least 85% of the nitrogens may be substituted. The carbonyl-containing moiety may include RCO—, where R is alkoxy or haloalkyl. The PBI compound may exhibit a first temperature marking an onset of weight loss corresponding to reversion of the substituted PBI that is less than a second temperature marking an onset of decomposition of an otherwise identical PBI compound without the substituted moiety.
