Polytropic head of compressor
WebApr 24, 2024 · Polytropic efficiency is a value used to describe the efficiency of a compressor. A polytropic process is more difficult to analyze than a system under the isentropic or adiabatic assumptions. The difficulty arises from the fact that heat flows in and out of the system, and this added energy changes some of the basic gas properties, … WebThe energy penalty shows for 20% CO2 composition of separation by the cooling process with the single‐stage compression is lower by around 123.9% and 128.8% in terms of compression work and ...
