Abstract

The development of methods is actual for creation on its basis of the automated system for calculation and designing of expander-compressor units (ECU) for cryogenic air separation plants (ASP). ECU allows to effeciently use the work of expansion of air in expander steps for compression of air at compressor step of the unit is described. In the beginning the method for calculation ECU is stated on the basis of the balance equations. Then the simplified algorithm of optimization calculation ECU. The analysis of efficiency of application ECU is executed in ASP of low pressure of average productivity. For this plants is developed ECU, the opportunity for optimization of size of part of expander current at a variation of air's temperature before expander step of the unit is considered.
