A conformal filter is disclosed having a plurality of sorbent beds oriented perpendicular to an inner side surface of the filter which conforms to an adjacent surface, such as a wearer's face when attached to a respirator. The inner side of the filter may approximate the curved shape of an interfacing surface. Because the sorbent beds are oriented perpendicular to the inner side surface, a conformal configuration can be achieved without bending the sorbent beds and while keeping constant bed residence time throughout the entire cross-sectional area of the air flow, thus enforcing even air distribution. Reduced bed depth is also achieved through this configuration which consequently reduces the overall pressure drop through the filter. Other embodiments are described and claimed. 1.

SYSTEM AND METHOD FOR CARBON DIOXIDE CAPTURE AND SEQUESTRATION FROM RELATIVELY HIGH CONCENTRATION CO2 MIXTURES

Номер: US20130312606A1
Автор: Eisenberger Peter
Принадлежит:

A system and method of reducing the net carbon dioxide footprint of an industrial process that generates power from the combustion of hydrocarbon fuels in which ambient air is admixed with up to 50% by volume of an effluent gas from the power generator of the industrial process, in order to substantially increase the COconcentration in the air prior to treatment. The treatment comprises adsorbing COfrom the admixed ambient air utilizing a cooled, porous substrate-supported amine adsorbent, wherein the porous substrate initially contacts the mixed ambient air containing condensed water in its pores, which act as an intrinsic coolant with respect to the exothermic heat generated by the adsorption process. In addition, prior to regenerating the supported adsorbent, air pressure is substantially reduced in the sealed regeneration chamber and the low pressure chamber is placed in fluid connection with a higher pressure regeneration chamber containing steam and carbon dioxide, to preheat the sorbent to be regenerated and to quickly cool the regenerated sorbent prior to use for further COadsorption. 1. A method of removing and capturing concentrated carbon dioxide from carbon dioxide laden air , the method comprisingadmixing a first flow of carbon dioxide-laden ambient air with not more than 50% by volume of an effluent gas, where the effluent gas is derived from a flue gas from the combustion of hydrocarbons, and directing the first flow of admixed ambient air to a first carbon dioxide removal structure; the carbon dioxide removal structure comprising a sorbent supported upon a porous substrate and capable of exothermically and releasably binding carbon dioxide to remove a predetermined portion of the carbon dioxide from the first admixed ambient air mixture;passing the first carbon dioxide removal structure into a first sealed carbon dioxide capture chamber, exhausting air from the first sealed capture chamber to reduce the air pressure therein, and passing steam, at a ...

CONTROL OF SWING ADSORPTION PROCESS CYCLE TIME WITH AMBIENT CO2 MONITORING

Номер: US20190111377A1
Автор: Celik Cem E., Dube Olivier, McNamara Thomas A.
Принадлежит:

The present invention relates to a method of controlling prepurifier cycle time by monitoring ambient COlevel in order to prevent CObreakthrough occurrences caused by extreme instantaneous variations in ambient COlevel. Rather than operating solely by prepurifier design bed capacity, the method of the invention continuously updates bed capacity for the contaminants using the feed temperature, pressure and contaminants composition, calculating the total amount of contaminants that were fed to the prepurifier during the feed step and estimates the perturbation front velocity, i.e., the velocity at which the contaminants front coming from an extreme instantaneous variations of ambient level is going to propagate inside the adsorbents bed. Estimating the perturbation front velocity allows for a more precise estimate of the maximum time remaining for the feed step before starting to experience CObreakthrough. This eliminates the need to switch the online bed unnecessarily early and risking shorter regeneration for the offline bed. 1. A method for maximizing the time an adsorbent bed can remain online in feed mode in a swing adsorption process without experiencing breakthrough of adsorbate , wherein said swing adsorption process comprises at least two adsorbent beds each having a predetermined design bed capacity , wherein one adsorber bed is online in feed mode during which adsorbate is adsorbed from a feed gas mixture passing through the bed , while another adsorbent bed is in regeneration mode , during which the adsorbed component is desorbed from the bed , wherein the beds alternate between said modes , said method comprising:a) Repeatedly measuring the feed gas flow rate, feed gas temperature, feed gas pressure and the concentration levels of adsorbate in said feed gas during the on-stream mode;b) Calculating the perturbation front velocity of the adsorbate through the adsorbent bed when there is a an instantaneous variation of ambient levels of said adsorbate in the ...
