The calculation and exergy analysis methods for the turbine expander-compressor units are considered. The calculation equations are obtained for compressor outlet and turboexpander inlet pressure calculation and for relation of reduced impeller diameters. The expander-compressor unit exergy efficiency is defined. The turboexpander efficiency is shown to have a greatest influence on the whole plant exergy efficiency because turboexpander works at low temperatures. The calculation of a real expander-compressor unit exergy characteristics with loss factors estimation is performed.
