Abstract
Method and apparatus for providing clean air to an environment. Incoming air, which may be contaminated with chemical, nuclear or biological contamination is initially cooled and water is removed from the cooled air by a first cooler, a first water separator, a second cooler and a second water separator. The cooled air is passed through a regenerative pressure swing absorption system which removes the contaminants. The resulting, cleaned, air is expanded by an expander. The expanded, cleaned air is provided to the environment, after being used in the second cooler to clean the incoming air.
Claims31
A method for providing clean air to an environment, the method comprising:
- compressing incoming air contaminated with nuclear, biological and chemical contaminants;
- cooling the compressed air to produce cooled compressed air;
- removing water from the cooled compressed air;
- enabling access to a regenerative pressure swing adsorption system;
- directing the cooled, compressed air through the regenerative pressure swing adsorption system;
- receiving, from the regenerative pressure swing absorption system, clean output air with contaminants removed therefrom;
- enabling access to an expander and using the expander to expand the cleaned air;
- providing the cleaned air to the environment;
- and
- enabling access to a first air cooler, a second air cooler, a first water separator and a second water separator;
- wherein cooling the compressed air and removing water from the compressed air includes passing the compressed air through the first cooler, passing the cooled air through the first water separator, passing the cooled air through the second cooler in which the cooled air is further cooled by cleaned air from the expander, and passing the air through the second water separator.
An apparatus for providing clean air to an environment comprising:
- a compressor for compressing inlet air;
- a first cooler for cooling the inlet air compressed by the compressor;
- a first water removal mechanism for removing water from the cooled, compressed air;
- a second cooler for further cooling the inlet air;
- a second water removal mechanism for removing additional water from the air;
- a regenerative pressure swing adsorption system for removing contaminates from the air;
- and
- an expander for expanding cleaned air from the pressure swing adsorption system for supply to the environment, in which the air is cooled in the second cooler by the cool expanded air from the expander.
