摘要： The present invention provides a method for preventing wax deposition in oilwells with packers. The method comprises feeding a motive fluid from a storage means to an ejector means 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 the annulus of the oil well having packers using the ejector means, wherein flowing of the motive fluid through the converging section and diverging section of the ejector means creates a pressure loss and increase the velocity of the motive fluid, which creates suction in the constricted section to evacuate water and vapour from the annulus of the oil well, thereby remediating wax deposition in the oil wells having packer.

摘要： 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.
