3114 results about "Air separation" patented technology

An air separation plant separates atmospheric air into its primary components, typically nitrogen and oxygen, and sometimes also argon and other rare inert gases. The most common method for air separation is fractional distillation. Cryogenic air separation units (ASUs) are built to provide nitrogen or oxygen and often co-produce argon. Other methods such as membrane, pressure swing adsorption (PSA) and vacuum pressure swing adsorption (VPSA) are commercially used to separate a single component from ordinary air. High purity oxygen, nitrogen, and argon used for semiconductor device fabrication requires cryogenic distillation. Similarly, the only viable source of the rare gases neon, krypton, and xenon is the distillation of air using at least two distillation columns.

The cooled gases are liquefied in the ASU and separated for sale or re-use in the power plant. Carbon dioxide liquid is transported from the plant for use in enhanced oil recovery or for other commercial use. Carbon dioxide removal is accomplished in the ASU by cryogenic separation of the gases, after directing the stream of liquid nitrogen from the air separation unit to the exhaust gas heat exchanger units to cool all of the exhaust gases including carbon dioxide, carbon monoxide, nitrogen oxides, nitrogen, oxygen, sulfur oxides, and other trace gases.

Low power nitrogen enriched air generation system

An inerting system provides air with reduced oxygen content by flowing and directing air through an air separation module. Optimal working pressure for the air separation module is obtained with two compressors. A first compressor elevates air from the aircraft cabin to a second pressure. The second pressure is at an intermediate level below the working pressure of the air separation module. A second compressor elevates air from the second pressure to the working pressure. The second compressor is driven by air that is exhausted through a turbine. The pressure difference between air at the working pressure and air required by the fuel distribution system is used to power the turbine and drive the second compressor.
