Modern air separation plants are often constructs on the basis of cycles of low pressure which have a number of advantages. The results of research works are stated in the field on development of plants of the small productivity using a cycle of low pressure for manufacture of liquid oxygen and nitrogen. Preliminary results on creation of automobile air separation plants «AOES-100» of new generation are considered. Its technological circuit accommodation of plant on transport base and characteristics is resulted. The earlier issued domestic analogues are comparison with modern foreign plant in which cycle of high pressure was applied.
