Resumo

The authors aimed to study the deasphalting process on laboratory scale through the design and development of a supercritical extraction experimental unit. Extractions in subcritical and supercritical conditions were carried out using petroleum residue as feedstock and propane 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 supercritical conditions, 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.
