Resumo(s)

This study presents an integrated approach in biogas upgrading technology through the development and optimization of a shaped MIL-160(Al)-based pressure/vacuum swing adsorption (PSA/VPSA) system. Combining detailed experimental investigations with comprehensive process modeling and techno-economic analysis, we demonstrate a complete pathway from fundamental dynamic adsorption to industrial implementation. Breakthrough tests reveal notable CO2/CH2 separation performance with shaped MIL-160(Al), while 23 cyclic PSA experiments achieved over 90 % methane purity. Advanced process modeling, validated with less than 5 % deviation from experimental data, enables successful scale-up to industrial VPSA configurations, where 38 distinct cases were evaluated to identify an optimal system producing 99.81 % pipeline-quality biomethane with 92.6 % recovery. Our holistic techno-economic assessment reveals the system's acceptable economic viability, with the total capital expenditure (CapEx) of $14.33 million. Accordingly, this work provides clear methodological insights that strengthen the understanding of MIL-160(Al)-based PSA/VPSA process and support its potential application for biogas upgrading.
