20150034474 | PROCESS FOR OBTAINING FOOD GRADE HEXANE - The present invention relates to a process for obtaining food grade hexane, comprising: fractionating a hydrocarbon feed having a boiling point in the range of 50° C. to 140° C. to obtain a hydrocarbon fraction having boiling point in the range of 63° C. to 69° C. and having 3%-15% (wt/wt) of aromatic compounds content; extracting the hydrocarbon fraction by counter current solvent extraction using sulfolane as a solvent to obtain a first raffinate phase; extracting the first raffinate phase by co-current solvent extraction using sulfolane as a solvent to obtain a second raffinate phase; and washing the second raffinate phase with water to obtain a food grade hexane containing less than 100 ppm of aromatic compounds. | 02-05-2015 |
20140156241 | PREDICTION OF REFINING CHARACTERISTICS OF OIL - Method(s) and a system for predicting the refining characteristics of an oil sample are described. The method of predicting the refining characteristics, such as distillate yield profile, processability, product quality or refinery processing cost, may include development of a prediction model based on regression analysis. The method may further include determining the physical properties of the oil sample and predicting the refining characteristics based on the developed prediction model. The determination of the physical properties of the oil sample includes determining at least one of Conradson Carbon Residue (CCR) content, Ramsbottom Carbon Residue (RCR) and Micro Carbon Residue (MCR). | 06-05-2014 |
