Using the second law first: Improving the thermodynamic efficiency of carbon dioxide separation from gas streams in an Endex calcium looping system

Ball, Rowena

Description

The most costly step in carbon capture from flue gas streams is regeneration of the pure CO2 stream from the sorbent, because of the high temperatures required by conventional systems. This work presents an entropy generation analysis of the new Endex calcium looping method, in which regeneration is driven directly by the heat of carbonation and pressure-swing is used to reduce the temperature of calcination. Entropy generation rates for the important subprocesses in the control volume are...[Show more]
