    摘要: A cryogenic air separation method and apparatus in which first and second liquid streams are produced. The first liquid stream has a higher oxygen content than air and can consist of a higher pressure distillation column bottoms and the second liquid stream, for instance, air, has a lower oxygen content than the first liquid stream and an argon content no less than the air. The second liquid stream is subcooled through indirect heat exchange with the first liquid stream and both of such streams are introduced into the lower pressure column. The second liquid stream is introduced into the lower pressure column above that point at which the crude liquid oxygen column bottoms or any portion thereof is introduced into the lower pressure column to increase a liquid to vapor ratio below the introduction of the second liquid stream and therefore, reduce the oxygen present within the column overhead.

    摘要: A distillation apparatus and method in which first and second compressed streams are formed from a compressed feed stream, for example, compressed air. The first compressed stream is fully cooled within a main heat exchanger so that it is substantially condensed. The second compressed stream is partly cooled within the main heat exchanger and then introduced into a turboexpander at a temperature such that the turboexpander exhaust stream is superheated. Part of the first compressed stream is mixed with the exhaust stream to produce a combined stream that is no more than 10° C. above saturation temperature at the pressure of the exhaust stream. The combined stream is introduced into a distillation column unit to produce one or more products that are enriched in components of the feed to be separated. In such manner the turboexpansion can occur at a higher temperature and with increased refrigerating effect.

    摘要: Systems and methods are disclosed for the power efficient production of high-pressure gaseous oxygen product. In a preferred embodiment, a liquid oxygen stream is pumped to a low to medium pressure and warmed within a first heat exchanger such as a brazed aluminum plate fin heat exchanger. The liquid oxygen stream is then pumped to a further pressure and then vaporized in a second heat exchanger to produce a high-pressure gaseous oxygen stream. In an embodiment, a high-pressure air stream may be utilized in the second heat exchanger for vaporizing the oxygen stream and cooling the air stream. The air stream may be utilized as a feed for the cryogenic air unit. A portion of the air stream at a medium pressure may be utilized in the first heat exchanger. A portion of the air stream may also be expanded to recover energy.
