Air separation plants of average pressure are mainly created for manufacturing of gaseous components of air. Their productivity in liquid modes appears insignificant. For increase of production of liquid oxygen in such conditions it is necessary to apply the additional sources of cold. Two variants of modernization of plant of average pressure are compared in article: with application of additional refrigerating machines or a nitrogen circulating contour. The modernization of air separation plants of average pressure with use of the equipment of factory’s reserve plants which efficiency has been kept is realize for confirmation of calculations. The modernized plant with an additional nitrogen circulating contour has provided the increase the output of production liquid oxygen with 165 up to 375 kg/h at decrease of specific expenses in 1,68 times.
