DEHYDRATING AND DESALTING MEDIAN, HEAVY AND EXTRA-HEAVY OILS USING IONIC LIQUIDS AND THEIR FORMULATIONS

摘要

The present invention relates to the application of ionic liquids individually or in formulation, such as drying and desalt crudes oils which API gravities are comprised in the range 8 to 12 (median, heavy and extra-heavy); when applied concentrations ranging from 500 and up to 5000 ppm. Ionic liquids consist of cation of type carboxymethane-ammonium, ammonium, imidazolium, isoquinolinium, pyridinium, and 1,5-dicarboxylic-pentane-2-ammonium in its positive and its negative part by anion such as R5COO-, Cl-, Br-, [BF4]-, [PF6]-, [SbF6]-, [R6SO4]-, [OTs]-, [OMs]-, which in turn is represented by chains R5 alkyl, cycloalkyl, benzyl, alkenyl, aromatic or alkyl functionalized between 1 and 18 carbon atoms; R6 in turn is represented by methy and ethyl.
