Methods and apparatus relate to recovery of carbon dioxide and/or hydrogen sulfide from a gas mixture. Separating of the carbon dioxide, for example, from the gas mixture utilizes a liquid sorbent for the carbon dioxide. The liquid sorbent contacts the gas mixture for transfer of the carbon dioxide from the gas mixture to the liquid sorbent. The carbon dioxide then desorbs from the liquid sorbent using hollow-fiber contactors as a source of heat to liberate the carbon dioxide further separated by the hollow-fiber contactors from the liquid sorbent.

Systems and methods for filtration

Номер: US20120298578A1

Принадлежит: Individual

Filtration systems ( 40 ) utilize a pre-treatment method to cause scale formation to occur on particles ( 94 ) in the fluid stream ( 96 ) rather than on the filter surface and may also destroy microorganisms in the fluid stream. More specifically, but not limited to, a filtration device can be a filtration membrane, such as spiral wound filtration membrane ( 60 ), that utilizes an open feed spacer ( 80 ), such for example an embossed or printed pattern on the membrane, to create a thin feed spacer channel which replaces a conventional feed spacer mesh material. System ( 40 ) further utilizes a treatment device ( 54 ) to enable a pulsed power, magnetic, electro-magnetic, electro-static, or hydrodynamic fluid treatment scheme to condition particles in the fluid stream ( 96 ) such that scale forming elements precipitate ( 94 ) on to the particles in the fluid stream rather than on the filtration surfaces.

Method for regulating the supply of substituting during extracorporeal blood treatment and extracorporeal blood treatment device comprising a unit for regulating the supply of substituate

Номер: US20120318739A1

Автор: Alfred Gagel, Pascal Kopperschmidt

Принадлежит: FRESENIUS MEDICAL CARE DEUTSCHLAND GMBH

The present invention relates to a method for regulating supply of substituate in an extracorporeal blood treatment with an extracorporeal blood treatment apparatus comprising a dialyzer divided by a semipermeable membrane into a blood chamber and a dialyzing fluid chamber and a device for supplying substituate. Moreover, the present invention relates to an extracorporeal blood treatment apparatus having a device for regulating supply of substituate. Regulation of supply of substituate in the extracorporeal blood treatment takes place as a function of the rheological loading of the dialyzer. To regulate supply of substituate during extracorporeal blood treatment, rheological loading of the dialyzer is determined from transmembrane pressure on the dialyzer and flow resistance of the dialyzer and substituate rate is increased or reduced according to the loading. The selection of dialyzer parameters or blood parameters is therefore no longer necessary and the distinction between pre-dilution and post-dilution is also made obsolete.
