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.

Hollow fiber membrane contactor scrubber/stripper for cabin carbon dioxide and humidity control

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.

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.

Dual stripper with water sweep gas

A pyrolysis reactor includes a chamber having an inactive section and an active section. The inactive section is configured to hold an inactive pre-form capable of adhering carbon. The active section is configured to hold an active pre-form capable of adhering carbon. An induction coil is outside of and operatively adjacent the active section, and wherein the active section is configured to pyrolyze a hydrocarbon.

Inductively heated methane pyrolysis reactor for advanced oxygen recovery in environmental control and life support systems

A gas distribution system may include a gas mass flow sensor with a resistive element configured to be heated, a thermally conductive shell surrounding the resistive element and heat-transfer control elements. The shell may include a leading surface oriented substantially orthogonal to a direction of gas flow. The heat-transfer control elements may be positioned to focus heat transfer from the resistive element through the leading surface of the shell so that a rate of heat transfer is independent from the variations in flow configuration.

System for gas distribution and mass flow measurement

An apparatus and method of measuring the mass of a test specimen located in a microgravity environment. The test specimen is attached to the free end of a cantilevered spring for joint vibration. The natural frequency of vibration of the spring and specimen are measured. The spring constant is calculated and compared with known masses having the same frequency and spring constant. When a match is found, the mass of the test specimen is known.
