Modeling asphaltenes for molecular dynamics simulations of sol vent deasphalting

摘要

The growing demand for products obtained from heavy oils and residues has led to the development of processes that can increase the efficiency of traditional refining operations. Solvent deasphalting (SDA) allows the recovery of lower molecular weight and parafinic components from residues that contain large amounts of asphaltic materials at relatively low temeratures, without cracking or degrading the heavier constituents.
