Abstract

The Instituto Colombiano del Petróleo (ICP), has implemented a methodology for separating vacuum residue fractions using the technique of supercritical fluid extraction at the pilot scale. The present study evaluates the efficiency of extraction of fractions of a typical vacuum residue in the Barrancabermeja refinery. The extraction test was carried out with n-hexane under supercritical conditions of temperature and pressure of the 265ºC in the range from 450 to 1250 psi, respectively. Finally, each of the fractions were analyzed for their density, viscosity, sulfur content, Conradson Carbon Residue (CCR) content, SARA com-positional analysis, and metals.

超临界萃取分离真空渣油馏分

哥伦比亚研究所Petróleo (ICP)在中试规模上采用超临界流体萃取技术分离真空残渣馏分。本研究评估了在Barrancabermeja炼油厂提取典型真空渣油馏分的效率。在温度265℃、压力450 ~ 1250 psi的超临界条件下，用正己烷进行萃取试验。最后，对每个馏分进行密度、粘度、硫含量、康拉德森碳渣(CCR)含量、SARA成分分析和金属成分分析。
