Abstract

This research has the aim to evaluate the effect that chemical additives have on the performance of extra heavy crude Hamaca extraction using propane as the extraction solvent in the condition of the deposit (60° and 1100 psi). The research began with an evaluation in a SFE ISCO extraction system with propane, using different additives, such as; toluene, toluene/isopropanol(IPA), dodecylbenzene sulfonic acid (ADBS), maleic anhydride (AM). Successive extractions of crude Hamaca were made in the presence of porous environment to the deposit conditions, in order to select the additives that offer better extraction performances of the extracted crude. Finally, one can say that additives have an important influence on the extraction performance, as well as the relation propane/crude to be used.
