ABSTRACT
In order to improve extraction capability of carbon dioxide (CO2) in the chemistry industry, a joint application of supercritical CO2 with some chemical modifiers such as alcohols is usually employed. Polar chemical modifiers such as methanol, is well known for its capability in extracting polar components of crude oil such as asphaltic. Most of the components in crude oils are, however, non-polar. This paper investigates the influence of non-polar chemical modifiers’ addition with CO2 on improving the crude oil extraction at immiscible conditions by using a micro-model system. From the experiments, it was found that extraction of crude oil improved with the addition of non-polar solvent with the highest oil recovery of 52.54% achieved by co-injection of gaseous CO2 and toluene, as compared to oil recovery of 27.4% by gaseous CO2 alone after 20 Pore Volume Injected (PVI).

KEYWORDS: carbon dioxide; non-polar chemical modifiers; micro-model system; immiscible condition; enhanced oil recovery
