Uncertainty analysis data for the study "Uncertainty and global sensitivity analysis of a membrane bi-ogas upgrading process using COCO simulator"

The files shown are related with the paper sent to ChemEngineering by the creators. The uncertainty analysis was performed using MonteCarlo propagation method with the number of evauations determined by Wilks formula (rank 2) to have 95% of probability content at 99% odf confidence level. Data were obtained using COCO simulator for a system described in Fig. 4.6 of [1] for the reference parameters of Table 1 for a non-controlled and pressure controlled scenario. The combination of factors were generated acording feed variability FV = +/-5% and +/-10%. The files arer identified with the scenario ("controlled" or "non-controlled" followed by 05 or 10 to indicate the FV used). Seed of random Matlab generator to determine factors combinations was stablish to default. Selectivity (pmcCO2/pmcCH4) to determine the base data for CH4 permeance is related to CO2 permeance using alfa = alfaCO2/CH4ref^(pmcCO2/pmcCO2ref)^-0.379 The files include: Column A: number case FACTORS: Column B: FBG = Flow of biogas treated (mol/h) Column C: xCO2BG = molar fraction of CO2 in the biogas (the rest being CH4) Column D: pmcCO2: permeance of the membrane to CO2 Column E: pmcCH4: permeance of the membrane to CH4 RESPONSES: Column F: xCO2BG = molar fraction of CO2 in the off-gas Column G: xCH4BM = fraction of CH4 in the biomethane produced Column H: EDC: Power demand of the compressor od the system (W) Column I: HDX: Heat duty to remove in the compression (W) to have 45 ºC.
