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, upgradation of wax, prevention of clogging of pipelines, processing of sludge or for removing sludge from petroleum tank installations and enhancing the crude oil flow.
