Abstract

In this study, new way to handle the determination of interfacial tension for asphaltenic crude oil and C02 using parachor method is proposed. Parachor is one empirical method that can be use to predict interfacial tension and is widely used in the industry. Parachor method is dependent on the phase density, molecular weight, parachor value for each components and the scaling exponent. Early studies defined the value of the scaling exponent to be 3.67, 3.88,3.91 and 4.00. However, these proposed values are not design to predict the 1FT for crude oil that contain asphaltenes more than 0.01%. As a result, the predicted 1FT gave an error when comparing the results with the laboratory determination. This paper used four types of asphaltenic crude oil that contain different percentage of asphalt. The samples are Dulang Crude Oil, Iraq Ratawi Crude Oil, and mixture of 80% Dulang Crude and 20% Iraq Ratawi Crude, and 20% Dulang Crude and 80% Iraq Ratawi Crude. To compare the empirical method, this project implemented 1FT pendant drop experiment as the main laboratory work. This paper compared the 1FT value from the experiment and the empirical method in order to come up with a method to encounter the error.
