7 results about "Carbon dioxide scrubber" patented technology

A carbon dioxide scrubber includes an adsorption chamber through which an adsorption airflow is directed, a regeneration chamber through which a regeneration airflow is directed, and a divider wall separating the adsorption chamber from the regeneration chamber. A carbon dioxide sorbent bed extends across the adsorption chamber and the regeneration chamber. The carbon dioxide sorbent bed is configured to adsorb carbon dioxide from the adsorption airflow into the sorbent bed and exhaust carbon dioxide from the carbon dioxide sorbent bed into the regeneration airflow. The carbon dioxide sorbent bed is continuously movable through the adsorption chamber and the regeneration chamber.

The present invention relates to a method and an apparatus for extracting CO2 from a gaseous medium, in particular ambient air, using a CO2 separation apparatus having: a CO2 scrubber that has a gas inlet and a gas outlet, a sorbent inlet at an upper end of the CO2 scrubber, and a first intermediate tank for receiving a CO2-enriched sorbent from the CO2 scrubber; and an electrodialysis apparatus for separating CO2 into a release medium. The method comprises the following steps: enriching the sorbent with CO2 in the CO2 scrubber and feeding the CO2-enriched sorbent into the first intermediate tank; discharging a first partial quantity of the enriched sorbent from the first intermediate tank into the electrodialysis apparatus; and recirculating a second partial quantity of the enriched sorbent from the first intermediate tank into the CO2 scrubber. The method is configured to be carried out continuously, semi-continuously or batchwise.

A contaminant removal system for removing contaminants from an environment includes a water management system and a carbon dioxide removal system. The water management system is configured to remove water from a cabin air stream using a first liquid sorbent to produce a dehumidified cabin air stream, and includes a water scrubber and a water stripper. The carbon dioxide removal system is configured to remove carbon dioxide from the dehumidified cabin air stream using a second liquid sorbent, and includes a carbon dioxide scrubber and a carbon dioxide stripper.

The utility model relates to the technical field of washing towers, in particular to a carbon dioxide washing tower for the cement industry, which comprises a device body, a gas inlet, a gas outlet, a gas inlet, a gas outlet and a gas outlet, a sealing structure is inserted into the waste gas inlet and comprises a positioning pile, and the outer wall of the positioning pile is sleeved with a sealing ring. One end of the positioning pile is inserted into the waste gas inlet, then the angle of the control rod is rotated to drive the sliding rod to move in the annular through groove formed in the sealing cover, and the sliding rod drives the threaded ring to rotate, so that the threaded ring is rotationally connected to the outer surface of the waste gas inlet to limit the sealing cover; the sealing cover abuts against the surface of one end of the waste gas inlet, the sealing cover is matched with the positioning pile and the sealing ring to seal the waste gas inlet, and the problem that dust and impurities in air enter the waste gas inlet to be accumulated, and consequently internal blockage is caused is solved.

A regenerable carbon dioxide scrubber includes at least a first housing compartment including an inlet, an outlet, and an interior region. A sorbent material is located within the interior region of the first housing compartment, in which the sorbent material (a) attracts and / or retains carbon dioxide from an air supply passing through the sorbent material at an operating temperature below about 100° C. and (b) releases carbon dioxide at a regenerating temperature above about 150° C. A rebreather including the regenerable carbon dioxide scrubber may be used to scrub carbon dioxide from a user's exhaled air.

The invention relates to a method for providing a hydrogen stream (7) in a facility (2) for providing the hydrogen stream (7), wherein a carbon-containing energy carrier stream (3) is fed to a syngas reactor assembly (4) in order to obtain a syngas stream (5) comprising hydrogen and carbon oxides, the syngas reactor assembly (4) obtains the syngas stream (5) from the energy carrier stream (3) by means of an autothermal reforming process, the syngas stream (5) is fed to a shifting apparatus (15a-c), a water-gas shift reaction taking place in the shifting apparatus (15a-c) in order to react at least part of the carbon monoxide of the syngas stream (5) with steam from the syngas stream (5) in order to form carbon dioxide and hydrogen, the syngas stream (5) is fed, downstream of the shifting apparatus (15a-c), to a carbon dioxide scrubber (30) in order to scrub at least part of the carbon dioxide from the syngas stream (5), a flash gas stream is released from a regeneration stage of the carbon dioxide scrubber (30), said flash gas stream being fed to a heating device of the facility (2) for an underfiring process, and the syngas stream (5) is at least partly fed, downstream of the carbon dioxide scrubber (30), to a separating assembly (6) in order to separate the syngas stream (5) at least into a hydrogen stream (7) comprising hydrogen and a carbon oxide-containing exhaust gas stream (8). The method is characterized in that, prior to being fed to the syngas reactor assembly (4), the energy carrier stream (3) is fed to a saturation stage (11), in which preheated condensate (12) accumulated in the facility (2) is fed to the energy carrier stream (3), and in that during the process of feeding the syngas stream to the shifting apparatus (15a-c), at least 80% of the steam fraction of the syngas stream (5) is already present as the syngas stream (5) exits the syngas reactor assembly (4). The invention likewise relates to a corresponding facility (2) for providing a hydrogen stream (7).

The ammonia production system comprises a syngas compressor upstream from the ammonia synthesis module includes an ammonia reactor. The ammonia reactor is fluidly coupled to the chiller which is in fluid communication with a carbon dioxide scrubber. The scrubber removes unreacted syngas. The unreacted syngas is recycled through a IGV controlled recycle compressor using a fixed speed driver. The delivery side of the recycle compressor is in fluid communication with the ammonia reactor. A portion of the recycle stream is delivery through an expander to the syngas make up compressor.
