Design of the Power Group for a 15 MW Supercritical Carbon Dioxide Plant

Design of power‐blocks for medium‐scale supercritical carbon dioxide plants

“…A one‐stage MC was initially modelled as discussed above. The preliminary geometry is reported in detail in 27 . Applying the 1D models described in Section 3.1, a centrifugal stage made of a shrouded impeller and an unvaned diffuser was designed.…”

“…From a thermodynamic perspective, more information (although partial) is available in 27 where the authors give a preliminary design of a three‐shaft layout for a 10‐MW power‐block and in the literature, throughout which design cases, CFD analyses and preliminary tests on small prototypes are reported for CO 2 centrifugal compressors. This literature was considered in the preliminary design phase of the turbomachines (detailed in Section 3), despite the fact that it refers to units smaller than those analysed in this paper.…”

sCO2 Power Plant for Industrial Waste Heat Recovery: a Case Study

“…Results of previous studies [4][5][6] have suggested that sCO 2 cycles could represent an appealing alternative to other candidates (steam and Organic Rankine Cycle plants), since steam plants are usually applied to recovery systems with greater heat potentials, while Organic Rankine Cycles can work only at medium-low temperatures and, consequently, the waste heat-to-power efficiency would be compromised.…”
