    Abstract: In some examples, a membrane module includes a fiber bundle. The fiber bundle includes a tubular first region and a tubular second region positioned around the tubular first region. One of the first or second regions includes hollow fibers oriented along an axis of the fiber bundle. Another of the first or second regions includes hollow fibers that are not colinear in a radial direction from the axis of the fiber bundle. A void fraction of the second region is different from a void fraction of the first region.

    Abstract: A mobile contaminant removal system includes a contaminant sorption system of a mobile atmosphere. The contaminant sorption system includes at least one scrubber and a liquid sorbent loop. The at least one scrubber includes a membrane separator and is configured to receive a spent air stream from a ventilation system of the mobile atmosphere, absorb one or more contaminants from the spent air stream into a liquid sorbent, and discharge a clean air stream to the ventilation system. In an absorption mode, the liquid sorbent loop circulates the liquid sorbent through the at least one scrubber in a closed loop. In a regeneration mode, the liquid sorbent loop discharges the liquid sorbent to a system external to the mobile atmosphere, such as a liquid sorbent storage system or a liquid sorbent regeneration system.

    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.

    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
