RE:Innovating in a silo
RE:Innovating in a siloWas there a slipped digit in that report? Because (comparing aldehyde to 1T1)
1.39 MJ/Kg = 1.39 GJ/tonne or 7X CST´s 0.2, and the process isn´t even fast.
Or is the devil in comparing "thermal energy requirement" to "parasitic load" ?
Novek et al
https://pubs.acs.org/doi/abs/10.1021/acs.estlett.6b00253
Thermal energy and temperature requirements for recovering acetaldehyde, the best-performing organic solvent investigated, and the CO2-absorbing solution were 1.39 MJ/kg of CO2 generated and 68 °C
CO2 press release apr 2015
Modelling of CO2 Solutions’ technology indicates that by using this low-grade heat, the effective parasitic load on the emitting power plant can be reduced to only 0.2 GJ/tonne of CO2 captured. Parasitic load is a measure for the reduction in efficiency of power generation plants as a result of bolt-on carbon capture processes and is the largest operating cost component of these same processes.
