Appropriate Placement of Compressors and Expanders
Apr 4, 2012
Truls Gundersen
The term “Appropriate Placement” was introduced in Pinch Analysis during the 1980s to indicate how special unit operations should be correctly integrated with the background process to ensure maximum energy savings. Pinch Analysis has provided guidelines for the design of heat exchanger networks as...
Thermodynamic Analyses of Solar Thermochemical CO2 Capture Via Calcination/Carbonation Cycle
