摘要：A product molecular weight distribution calculating model of residue solvent deasphalting has been built based on continuous thermodynamics and combined with simplified perturbed hard chain theory equation of state (SPHCT EOS). Deasphalted oil (DAO) and deoiling asphalt (DOA) molecular weight distribution as well as DAO yield (w) of butane solvent deasphalting have been obtained with the model under different temperature, pressure, and solvent ratios for a specific vacuum residue. Results indicated that the model was feasible and could be used as a basis to predict product properties and optimize operating conditions as well as as a foundation to build other refinery process models with continuous thermodynamics.
