Abstract
A method for air distillation with production of argon using an air distilling installation (1) comprising an air distilling apparatus (2) in particular with double column, and at least one column for producing impure argon. The installation has dimensions for supplying argon with a nominal yield &rgr;,of argon extraction at the impure argon producing column output. For reduced argon production requirements corresponding to a required yield &rgr; of argon extraction at the impure argon producing column output, with &rgr;≦&rgr;,≦&rgr;,where &rgr;,is a predetermined optimal yield, the argon extraction yield in the impure argon producing column is maintained at the value &rgr;,.
