FORMULATIONS COMPRISING AN ASPHALTENE-DISPERSING/INHIBITING ADDITIVE BASED ON OXAZOLIDINES DERIVED FROM POLYALKYL OR POLYALKENYL N-HYDROXYALKYL SUCCINIMIDES |
摘要 |
The present invention relates to formulations of asphaltenes' inhibitor-dispersant additives based on oaxazolidine derived from polyalkyl or polyalkenyl N-hydroxyalkyl succinimides. Said formulations can contain inert organic solvents, preferably including: toluene, mixtures of xylene, o-xylene, p-xylene, kerosene, turbo-fuel; or inert hydrocarbon solvents having boiling points within the range of gasoline and diesel; or inert hydrocarbon or organic solvents having a boiling point within a range from 75 to 300°C. The ratio in weight of inert organic solvents to additive that prevents and controls the precipitation and deposition of asphaltenes ranges from 1:9 to 9:1, preferably from 1: 3 to 3:1. |
