Patent number: 10344236Abstract: The present invention relates to a process for preparing fuel-in-water emulsions from oil refining residues, in both continuously or in batches, by adding an emulsifying agent to disperse the residual oil in water and facilitate its transportation. This process does not require the use of chemical substances like stabilizers or diluents for its preparation. The vacuum residue is not limited to specific characteristics and the water used, can be distilled, tap water or saltwater (seawater). The process requires low concentration of a non-ionic surfactant; and the emulsions obtained have proportions from 70 to 90% by weight of refining residues, 10 to 30% by weight of water and from 0.1 to 1% by weight of surfactant. The fuel-in-water emulsion is produced from oil refining residues, such as residues of atmospheric and vacuum distillation, heavy fuel oils and similar, and it is formed from 70 to 90% by weight of refining residues, 10 to 30% by weight of water and from 0.1 to 1% by weight of non-ionic surfactant.Type: GrantFiled: December 9, 2015Date of Patent: July 9, 2019Assignee: INSTITUTO MEXICANO DEL PETRÓLEOInventors: René Ocampo Barrera, Martha García Espitia, Andrés Alberto Ceballos Serena

Patent number: 10309951Abstract: A portable, single-phase bioreactor provides the in situ study of mesophilic and thermophilic corrosion inducing microbial biofilms on metal surfaces by oil, chemical, petrochemical, oil refining, food, metallurgical, paper fluids. The bioreactor is a batch-type for turbulent and piston-driven laminar flow, operated by cycles, with continuous circulation of the fluid. A culture medium or industrial or production fluid containing microbiota is introduced into a homogenizing container. The bioreactor includes a support section having removable corrosimetric test coupons that contact the fluid under dynamic conditions corresponding to fluid-carrying pipelines, and promote the formation of the microbial biofilm for analysis of the kinetics of microbial biofilm development. The bioreactor produces turbulence to homogenize the fluid and maintain a temperature of 20 to 80° C. for the microorganism growth. The fluid has a salinity of 2 to 200 ppm (NaCl) and a pH of 2 to 10.Type: GrantFiled: August 19, 2016Date of Patent: June 4, 2019Assignee: INSTITUTO MEXICANO DEL PETROLEOInventors: Norma Icoquih Zapata Penasco, Vicente Garibay Febles, Florentino Leyte Guerrero, Ubaldo Sadott Pacheco Y Alcala, Jorge Alberto Mendoza Perez, Jesus Emmanuel Juarez Rojo

Publication number: 20190126254Abstract: According to this invention, a Ni—Mo—W trimetallic catalyst supported on porous alumina is obtained that shows very high activity for hydrotreating (HDT) of gasoils, particularly deep hydrodesulfurization (HDS) and hydrodesnitrogenation (HDN) of straight run gasoil in conditions of moderate pressure. When the catalyst is applied to HDT of diesel, the NiMoW catalyst exhibits high catalytic activity. The content of sulfur and nitrogen in the resulting diesel can be reduced from 13,200 to 10 ppm and nitrogen from 360 ppm to less than 1 ppm, under moderate pressure, temperature and space-velocity (LHSV) similar to those of an industrial unit.Type: ApplicationFiled: October 12, 2018Publication date: May 2, 2019Applicant: INSTITUTO MEXICANO DEL PETRÓLEOInventors: BLANCA LUCIA MEDELLÍN RIVERA, GONZOLO HERNÁNDEZ TAPIA, MARIA del Rosario Socorro LUNA RAMÍREZ, LEONARDO DÍAZ GARCÍA, MARIA TERESA GÓMEZ PÉREZ, ROBERTO GARCIA DE LEÓN

Patent number: 10221349Abstract: This invention is directed to a method for defoaming crude oil by the addition of copolymers based on silicone free alkyl acrylics defoamers for crude oils with densities between 10 and 40° API. The alkyl acrylic copolymers at conditions similar to those of gas-liquid separators are efficient foam formation inhibitors in heavy and super-heavy crude oils to reduce foam levels between 15 and 50% faster than non-dosed crude oil. Some acrylic copolymers exhibited a greater efficiency as defoamers than commercial silicones, which promote the defoaming only 20 or 25 vol % faster than the natural foam collapse. Silicones as defoamers present serious problems as the formation of deposits and the deactivation of catalysts in the refining processes. These problems have originated a series of interdictions to use silicon based defoamers and new chemical compounds completely silicon free are required to control the foam levels in the gas/petroleum separation tanks.Type: GrantFiled: July 13, 2016Date of Patent: March 5, 2019Assignee: INSTITUTO MEXICANO DEL PETROLEOInventors: Edgar Ivan Hernandez Carbajal, Enrique Cevada Maya, Alfonso Lopez Ortega, Cesar Andres Flores Sandoval, Fernando Alvarez Ramirez, Arquimedes Estrada Martinez, Flavio Salvador Vazquez Moreno

Patent number: 10213708Abstract: The present invention relates to the application based on alkyl acrylate homopolymers, such as antifoaming agents in crude oils with densities of 10 to 40° API. Evaluation tests in “live” crude oil, under similar gas-liquid separation equipment conditions, showed that these polymers based on alkyl acrylate are effective foaming inhibitors in heavy and super-heavy crude oils, reducing the foam between 15 and 50% faster compared to crude oil without an antifoaming agent. Some acrylics show better performance than commercial silicon-based polymers, which suppress foam 20-25% faster than the blank. The antifoaming agents of this invention, based on alkyl acrylate and totally free of silicon, is an advantageous option, to replace the silicone-based foam inhibitors currently on the market.Type: GrantFiled: December 4, 2014Date of Patent: February 26, 2019Assignee: INSTITUTO MEXICANO DEL PETROLEOInventors: Enrique Cevada Maya, Laura Veronica Castro Sotelo, Edgar Ivan Hernandez Carbajal, Cesar Andres Flores Sandoval, Alfonso Lopez Ortega, Aristeo Estrada Buendia, Fernando Alvarez Ramirez, Arquimedes Estrada Martinez, Flavio Salvador Vazquez Moreno
