Abstract

Abstract: This paper introduces the process of reciprocating compressor thermal re-calculation through one example. It makes a qualitative analysis on the interstage pressure ratio change when the compressor inlet or outlet pressure changes and arrives at the conclusion that the final stage pressure ratio changes the most. Meanwhile, this paper makes a precise calculation of the interstage pressure ratio change and re-balance process using HYSYS. The above conclusion can provide reference for compressor operation, selection calculation and calibration calculation.

Key words: inlet or outlet pressure change, interstage pressure ratio, reciprocating compressor, HYSYS simulation
