Solar weighted absorption fraction
WebThe interfacial area is the most sensitive parameter on absorber performance, whereas the heat of desorption is the prevailing parameter in the stripper. The CO2 equilibrium constant is a sensitive parameter in both absorption and stripping units. The two film models are compared and give similar results for the monoethanolamine solvent. WebUsing a mean solar S-value which is approximately weighted by the span of measurements (S⊙ = 0.176; for ∼1966-2006) and a mean solar color of B−V = 0.65 (Cox 2000), and using the equations from Noyes et al. (1984), we estimate the mean solar activity to be logR′ HK = –4.91. We also give in Table 1 the 68% and 95% range of the observed ...
