This submission contains an Aspen Plus V12.1 file (.bkp) and a ProMax V6 file (.pmx) as part of the publication "Design of biocarbon by-product utilization processes for ironmaking and steelmaking". The Aspen Plus file contains a simulation of an autothermal reforming reactor for a bio-oil model using an RGibbs block, as well as heat exchangers and condensers used for determining equipment and utility costs. The ProMax file contains a simulation of a carbon dioxide removal process using an absorber and stripper loop with recycled MDEA solvent.
