Process for the cryogenic distillation of an air feed to produce an ultra-high purity oxygen product
Patent number: 5425241Abstract: A process is set forth for the cryogenic distillation of an air feed to produce an ultra-high purity oxygen product. A first oxygen-containing but heavy contaminants-lean (free) stream is removed from the main distillation column system and subsequently stripped in an auxiliary distillation column. A second oxygen-containing but light contaminants-lean (free) gaseous stream is also removed from the main distillation column system and subsequently fed to the bottom section of the auxiliary distillation column in order to provide heat duty/reboil to the bottom of the auxiliary distillation column. The ultra-high purity oxygen product (ie total contaminant concentration less than 10.0 vppm, preferably less than 1.0 vppm) is withdrawn from an intermediate section of the auxiliary distillation column.Type: GrantFiled: May 10, 1994Date of Patent: June 20, 1995Assignee: Air Products and Chemicals, Inc.Inventors: Rakesh Agrawal, Donald W.
