Abstract

Possibility of application of mixture propane/ethane as perspective working body in propane refrigerating unit included in complex of low-temperature condensation of natural gas are considered. For the description of work of unit on a mixture propane/ethane the characteristics of turborefrigerating unit are modelled. The analysis of characteristics of the compressor allows to draw a conclusion on frameworks operating modes of unit on a new working body, and also about its power parameters. At operation of the two-section centrifugal compressor on a mixture it is necessary to coordinate the work of compressor sections in view of streams of the basic and overcooling cycles. Settlement researches have allowed to define the necessary operating conditions of unit on a new working body (the required temperature of condensation and refrigerating capacity), and also to make an estimation of power efficiency of the compressor of turborefrigerating unit.
