  • Publication number: 20230399576
    Abstract: The present invention relates to supramolecular surfactants (SS) with detergent-dispersant of heavy organic compounds (deposits and/or organic scales) and corrosion inhibition properties, and methods for preparing these surfactants. The invention also relates to the corresponding uses and applications of these surfactants to prevent and control the formation of deposits in internal combustion machines, as well as to prevent and protect pipelines, tanks, motors and complements of ferrous materials against corrosion where there is contact with liquid hydrocarbons such as gasoline, turbosine, and diesel, where gasoline may contain oxygenated compounds such as ethers and/or alcohols. The supramolecular surfactants are obtained from the self-assembly process between oxazolidines derived from polyalkyl/polyalkenyl N-hydroxyalkyl succinimides with alkyl/alkenyl-amine-propanoic acids and alkyl/alkenyl-amine-di-propanoic acids.

  • Patent number: 11149185
    Abstract: The present invention is related to the obtaining and using of multifunctional foaming compositions with wettability modifying, corrosion inhibitory and inhibitory/dispersants mineral scale properties with high stability in environments of high temperature, high pressure and tolerance to high concentrations of divalent ions such as calcium, magnesium, strontium and barium. The multifunctional foaming compositions are obtained from the combination of supramolecular complexes resulting from interactions of alkyl amido propyl hydroxysultaines and/or alkyl amido propyl betaines and/or alkyl hydroxysultaines and/or alkyl betaines and anionic surfactant of type alkyl hydroxyl sodium sulfonate and alkenyl sulphonates of sodium, with cationic surfactants as tetra-alkyl ammonium halides and copolymers derivatives of itaconic acid/sodium vinyl sulfonate and/or terpolymers derived from itaconic acid/sodium vinyl sulphonate/aconitic acid.

  • Patent number: 11046605
    Abstract: Random copolymers from itaconic acid and/or isomers and sodium alkenyl sulfonates are obtained by polymerization in an aqueous solution via free radicals at an acidic pH in the range from 1.0 to 3.5 and with a redox system as initiator were described. The copolymers can be used as calcium carbonate and calcium, strontium and barium sulfates mineral scale inhibitors and as dispersants of clays, iron oxides, calcium carbonate and strontium, barium and calcium sulfates. Random copolymers prevent and control damage in an oil reservoir, obstruction of water injection and crude oil production pipelines, and in production rigs due to mineral scale precipitation caused by high levels of salinity of the injection water and formation water. Random copolymers are tolerant to high concentrations of divalent ions, such as calcium, magnesium, strontium and barium, and can be added to the reservoir and to injection or production pipelines, treated water, sea water and water that is used as means of transportation.

  • Patent number: 9469804
    Abstract: A foaming composition with wettability-modifying and corrosion inhibitory properties is used to control the channeling of fluids in naturally fractured carbonate reservoirs, favorably alter the rock wettability in crude oil enhanced recovery processes and control uniform corrosion problems occurring in production rigs under high temperature and ultra-high salinity conditions by the synergistic effect resulting from the supramolecular interaction of alkyl amido propyl hydroxysultaines or alkyl hydroxysultaines with sodium alkyl hydroxysulfonates and sodium alkenyl sulfonates having the formula (1). The foaming compositions with wettability-modifying and corrosion inhibitory properties are tolerant to high concentrations of divalent ions such as calcium, magnesium, strontium and barium and are suitable for use in the reservoir, seawater and/or congenital water characteristic of the reservoir for transporting the crude oil from the reservoir.
