Abstract

The creation of relative low-flow expander-compressor aggregate (ECA) for useful use of energy of expansion of air in cryogenic air separation units is actual (ASU) to average productivity, basing on thermodynamic cycles of low pressure. In given article design procedure ECA is described on the basis of the balance equations connecting the basic characteristics compressor and expander of stages. Results of calculations ECA are resulted, intended for work in structure ASU low pressure with distribution of 230 kg/h and 260 kg/h, accordingly, liquid oxygen and nitrogen.
