|Title:||Development Of The Supercritical Deasphalting Pilot Plant For Petroleum Residue And Thermodynamic Evaluation Of Heavy Oil Supercritical Extraction|
Wolf Maciel M.R.
Maciel Filho R.
|Abstract:||The supercritical deasphalting pilot plant was developed for application on upgrading of heavy petroleum fractions from vacuum distillation and molecular distillation. A method for deasphalting using supercritical fluid as solvent, which involves the separation of the vacuum residue in two fractions, i.e., deasphalted oil and asphaltenes, is put forward. The system is equipped with an extractor, a separator, a propane reservoir, valves, pumps, a refrigerating system, and temperature controllers. The stages and the modifications that resulted in the equipment final design are presented. The thermodynamic study of the phase equilibrium of the system propane-oil-asphalt was developed. This is an abstract of a paper presented at the 18th International Congress of Chemical and Process Engineering (Prague, Czech Republic 8/24-28/2008).|
