Abstract: The authors aimed to study the deasphalting process on laboratory scale through the design and development of a subcritical and supercritical extraction experimental unit. The experimental unity used in tests is composed by a pump, an extractor with useful volume of 3 L and one separator vessel. Extractions in sub-and supercritical conditions were carried out using petroleum residue (vacuum residuum) as feed-stock and ethylic alcohol as solvent. Temperature and pressure were manipulated in order to maintain the solvent in the required conditions, thus facilitating the extraction process and avoiding sharp changes in the system. In both phases, the products in the deasphalted oil stream present adequate characteristics for the production of lubricant oils and those in the asphalt residue stream present an elevated concentration of asphalt molecules.
