Transportation of waxy crude oil along horizontal pipeline usually requires extra energy that costs additional billions of dollars to the industry. This study investigated the feasibility of Methyl Ethyl Ketone (MEK) as a selective solvent to dewax an Australian heavy crude oil and the possible optimum conditions. Experiments were conducted on three solvent to crude oil ratios (10 : 1, 15 : 1 and 20 : 1), three mixing temperatures (40°C, 50°C, and 60°C) and three cooling temperatures (-10°C, -15°C and -20°C). Each crude oil sample was weighed out and mixed with MEK at a predetermined mass ratio; the mixture was then heated in a hot water bath and stirred until a thermal equilibrium was achieved. The mixture was then placed in an ethylene glycol bath which had been cooled to the desired temperature using dry ice until the targe.. View More»
