Abstract
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.
Claims19
A contaminant removal system, comprising:
- a water management system configured to remove water from a cabin air stream using a first liquid sorbent, wherein the water management system comprises;
- a water scrubber configured to absorb water from the cabin air stream into the first liquid sorbent;
- and
- a water stripper configured to desorb water from the first liquid sorbent into a decontaminated air stream;
- and
- a carbon dioxide removal system configured to remove carbon dioxide from a dehumidified air stream using a second liquid sorbent, wherein the carbon dioxide removal system comprises:
- a carbon dioxide scrubber configured to:
- receive the dehumidified air stream from the water scrubber;
- absorb carbon dioxide from the dehumidified air stream into the second liquid sorbent;
- and
- discharge the decontaminated air stream to the water stripper;
- and
- a carbon dioxide stripper configured to desorb carbon dioxide from the second liquid sorbent into a contaminant stream.
A method for removing contaminants from an environment, comprising:
- removing, by a water management system, water from a cabin air stream using a first liquid sorbent to produce a dehumidified air stream, wherein the water management system comprises a water scrubber and a water stripper, and wherein removing the water from the cabin air stream includes at least:
- absorbing, by the water scrubber, water from the cabin air stream into the first liquid sorbent;
- and
- desorbing, by the water stripper, the water from the first liquid sorbent into a decontaminated air stream;
- and
- removing, by a carbon dioxide removal system, carbon dioxide from the dehumidified air stream using a second liquid sorbent, wherein the carbon dioxide removal system comprises a carbon dioxide scrubber and a carbon dioxide stripper, and wherein removing the carbon dioxide from the dehumidified air stream includes at least:
- receiving, by the carbon dioxide scrubber, the dehumidified air stream from the water scrubber;
- absorbing, by the carbon dioxide scrubber, carbon dioxide from the dehumidified air stream into the second liquid sorbent;
- discharging, by the carbon dioxide scrubber, the decontaminated air stream to the water stripper;
- and
- desorbing, by the carbon dioxide stripper, carbon dioxide from the second liquid sorbent into a contaminant stream.
