A chemical process for separating air into both oxygen and purified nitrogen is disclosed. Bulk oxygen removal is accomplished using an oxygen acceptor such as molten alkali nitrite solution, SrO, or Pr-Ce oxides. The remaining oxygen is removed by reaction with a scavenger such as MnO or others. The oxidized scavenger is regenerated by a reducing gas, and the heat released by the combined scavenging reactions is used to furnish at least part of the energy required by the acceptor process.
