Abstract

See full text

Nitrogen gas of high purity is produced from compressed air by contacting the air with a first gas membrane separator permitting oxygen to permeate therethrough selectively while restraining the passage of nitrogen. The nonpermeant gas is then brought into contact with a second gas membrane separator of similar construction. The use of the serially arranged separators provides nitrogen gas with very low levels of oxygen.
