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.
