Abstract: A system for generating methane includes a scrubber, a stripper, a vacuum pump, a water separator, and a Sabatier reactor. The scrubber is configured to absorb one or more contaminants from an air stream into a liquid sorbent, in which the one or more contaminants include carbon dioxide. The stripper is configured to desorb the one or more contaminants from the liquid sorbent. The vacuum pump is configured to pressurize the desorbed contaminants to a reaction pressure of the carbon dioxide. The water separator is configured to remove water from the pressurized, desorbed contaminants. The Sabatier reactor is configured to generate the methane from the carbon dioxide of the pressurized, desorbed contaminants.

Abstract: An aircraft contaminant removal system includes one or more membrane separators configured to absorb a contaminant from a cabin air stream into a liquid sorbent, desorb the contaminant from the liquid sorbent, discharge the contaminant in a contaminant stream, and return clean air back to the cabin. In some examples, the contaminant removal system includes a membrane scrubber-separator and a membrane stripper-separator, while in other examples, the contaminant removal system may include a single membrane separator configured to operate in a scrubbing mode and a stripping mode. The contaminant removal system may include a humidity management system configured to maintain a humidity of the clean air stream or water concentration of the liquid sorbent using one or more water sources of the aircraft or a thermal management system configured to maintain a temperature of the liquid sorbent using one or more heat exchangers fluidically coupled to an aircraft air stream.

Abstract: An environmental control system includes an air conditioning subsystem and a contaminant removal subsystem downstream of the environment to be conditioned. The contaminant removal subsystem includes: a first gas-liquid contactor-separator; a second gas-liquid contactor-separator; and a dehumidifier disposed either upstream of the first gas-liquid contactor-separator or downstream of the second gas-liquid contactor-separator.

Abstract: A contaminant removal system for removing a contaminant from an environment includes a gas separator, a scrubber-separator downstream of the gas separator, and a stripper-separator downstream of the scrubber-separator. The gas separator is configured to receive a cabin air stream from the environment and concentrate the contaminant from the cabin air stream to produce a concentrated cabin air stream. The cabin air stream includes the contaminant, and the concentrated cabin air stream has a higher concentration of the contaminant than the cabin air stream. The scrubber-separator is configured to absorb the contaminant from the concentrated cabin air stream into a liquid sorbent and discharge a clean air stream to the environment. The stripper-separator is configured to desorb the contaminant from the liquid sorbent into a contaminant stream.

Abstract: An environmental control system includes an air conditioning subsystem and a contaminant removal subsystem downstream of the environment to be conditioned. The contaminant removal subsystem includes a first gas-liquid contactor-separator, a second gas-liquid contactor-separator, and a third gas-liquid contactor-separator. One of the first, the second, and the third gas-liquid contactor-separators is configured to receive used absorbent liquid having at least a first contaminant and discharge at least a first contaminant for recovery and reuse. Another of the first, the second and the third gas-liquid contactor-separators is configured to receive used absorbent liquid having at least a second contaminant and discharge at least the second contaminant for recovery and reuse.

Abstract: A contaminant removal system includes a scrubber and an ionic liquid regeneration assembly. The scrubber is configured to absorb a contaminant from an air stream into an ionic liquid sorbent in an ionic liquid mixture. The ionic liquid regeneration assembly is configured to desorb the contaminant from the ionic liquid sorbent and remove liquid water from the ionic liquid mixture. The ionic liquid regeneration assembly may include a stripper for desorbing the contaminant and one or more reverse osmosis (RO) or nanofiltration (NF) membranes for removing the liquid water from the ionic liquid mixture.

Abstract: A spacesuit contaminant removal system includes at least one membrane separator and a liquid sorbent circuit. The at least one membrane separator is configured to receive a spent air stream from a ventilation system of a spacesuit and absorb a contaminant from the spent air stream into a liquid sorbent. The at least one membrane separator is configured to discharge a clean air stream to the ventilation system and discharge the contaminant in a contaminant stream to a space environment using a vacuum of the space environment. The liquid sorbent circuit is configured to circulate the liquid sorbent through the at least one membrane separator.
