Multivariable optimization and thermodynamic analysis of a mixed-refrigerant-precooled hydrogen liquefaction process
Description
This dataset supports the multivariable optimization and thermodynamic analysis of a mixed-refrigerant-precooled hydrogen liquefaction process. It contains direct Aspen HYSYS V14 simulation results, processed performance and sensitivity data, heat-exchanger composite-curve data, equipment-level exergy results, hydrogen-property and ortho–para conversion analyses, and paired optimization-algorithm benchmark results. The dataset includes 97 direct HYSYS evaluations, a 235-case enriched simulation archive, figure and table source data, Python analysis and reproduction code, and the author-selected H2_Liquefaction_Case1.hsc model. The HYSYS model was validated as converged and feasible at a liquid-hydrogen product pressure of 130 kPa. A Word reproducibility guide, file-level SHA-256 manifest, validation metadata and data-to-manuscript mapping are also provided.
