fully recreate and validate a research-level chemical engineering model from a published paper, using Aspen Custom Modeler (ACM only). In simple terms, he wants you to: Rebuild the rotating packed bed (RPB) CO₂ stripper/regenerator described in the paper from scratch in ACM Convert what was originally done with Aspen Plus + FORTRAN subroutines into native ACM equations and blocks Implement all governing equations: Mass and energy balances Chemical reaction kinetics Gas–liquid mass transfer correlations Heat transfer and hydrodynamics specific to RPBs Validate the model using the pilot-plant experimental data (Cheng et al.) reported in the paper Prove that your ACM results match the literature And deliver: ✔ A working ACM model file ✔ An Excel file comparing simulation results vs experimental data ✔ A Word document explaining assumptions, equations, correlations, and how everything was implemented step-by-step in ACM Who they want: Someone with very strong Aspen Custom Modeler experience Deep knowledge of CO₂ absorption/stripping, mass transfer, and RPBs Experience translating FORTRAN subroutine logic into ACM Ideally a PhD-level researcher or equivalent background
