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.
Claims16
An environmental control system, comprising:
- an air conditioning subsystem;
- a contaminant removal subsystem downstream of the environment to be conditioned;
- wherein the contaminant removal subsystem includes:
- a first gas-liquid contactor-separator;
- a second gas-liquid contactor-separator;
- and
- a dehumidifier disposed downstream of the second gas-liquid contactor-separator to produce a sweep gas to the second-gas liquid contactor-separator.
