Abstract: A method of screening solvents for the solubilization of petroleum hydrocarbons is disclosed. The method includes dissolving petroleum hydrocarbons in a selected solvent to form a first solution, adding an ionic liquid to the first solution and blending to form a second solution and measuring absorbance of the second solution using spectroscopic techniques. The solubilization of petroleum hydrocarbons in the solvent is then determined based on the difference between the measured absorbance of the first and second solution. A system for screening solvents for the solubilization of petroleum hydrocarbons is also disclosed. The system can be used in removal of wax deposition in refinery process equipment, process flow lines, during piping operations, up-gradation of wax, prevention of clogging of pipelines, processing of sludge or for removing sludge from petroleum tank installations and enhancing the crude oil flow.

Abstract: A method for preventing wax deposition in oil wells with packers is disclosed. The method includes feeding a motive fluid from a storage tank to an ejector having a converging section for inlet of the motive fluid, a diverging section for outlet of the motive fluid, and a constricted section with an opening in between the converging section and the diverging section; removing a water and water vapor from an annulus of the oil well using the ejector, wherein flowing of the motive fluid through the converging section and diverging section of the ejector creates a pressure loss and increases the velocity of the motive fluid, which creates suction in the constricted section to evacuate water and vapor from the annulus of the oil well, thereby remediating wax deposition in the oil well.
