Appl. No.:

7/849261

Assignee:

The BOC Group plc - Surrey

International Classification:

B01D 5304

US Classification:

95 98

Abstract:

A process for separation of a gas mixture containing three components, e. g. a mixture comprising hydrogen, carbon monoxide and carbon dioxide produced by steam reforming a hydrocarbon, by pressure swing adsorption is disclosed. In one embodiment of the process, the gas mixture is sequentially passed through first and second adsorptive regions each of which adsorbs a second component more strongly than a first component but less strongly than a third component, a first fraction enriched in the first component is withdrawn from the downstream end of the second region, introduction of gas mixture to the first region is stopped and the second region is closed to the first region, a second fraction enriched in the second component is withdrawn first from the upstream end of the second adsorptive region while passing gas mixture enriched in the third component into the first region from its upstream end and then from the downstream end of the first region, and withdrawing a third fraction enriched in the third component from the upstream end of the first region. The separation process is also applicable to other gas mixtures such as a mixture of hydrogen, argon, methane and nitrogen commonly available as ammonia plant purge gas from which ammonia has been removed.

The BOC Group, Inc. - Montvale NJ

International Classification:

B01D 5304

US Classification:

55 25

Abstract:

This invention relates to an energy efficient method of vacuum regenerating an adsorbent bed. In a typical process, the adsorbent bed undergoes an adsorption step, a vent step, and a vacuum purge step. According to the present invention, the energy of the usually discarded vent gas is used to raise a dense liquid from a lower tank to a higher tank. The potential energy of the raised liquid, upon returning from the higher tank to the lower tank, is used to generate a vacuum for vacuum regeneration of the adsorbent bed.

International Classification:

B01D 5304

US Classification:

55 26

Abstract:

Argon and nitrogen are produced in a basic two step process. In a first step, oxygen is removed from a compressed air feed using low temperature PSA (pressure swing adsorption). In the second step, argon and nitrogen mixture is separated by cryogenic distillation. The process yields crude liquid argon and very high purity gaseous nitrogen.
