Abstract: The present invention offers some general specifications for the design, assembly, and adaptation of a rotating cylinder electrochemical cell into an autoclave, of a high temperature and pressure system for corrosion studies that simulate operating conditions in pipelines, as well as the operation and safety of an autoclave to evaluate the electrochemical process of metal surfaces exposed to aggressive aqueous solutions. The electrochemical cell consists of an array of three electrodes that include a rotating cylinder electrode designed to operate hermetically, a reference electrode and an auxiliary electrode. The rotating cylinder electrode is considered to be the working electrode, where the oxidation and electrochemical reduction processes are studied. However, the use of the method described in this work can be extended to other testing environments and materials by taking into account the physical and chemical properties of the fluids and materials to be used in order to avoid any risk for the operator.

Abstract: This invention is related to the synthesis of organic carbonates from carbon dioxide and epoxides. It is particularly focused on the production of propylene cyclic carbonate from propylene oxide. The proposed catalytic materials includes a support made of aluminum oxyhydroxide (Catapal B®), nitric acid, acetic acid and/or phosphoric acid. An important stage is the physical and chemical conditioning of the catalytic materials and to this end, experimental methodologies such as spheronization and thermal treatments were implemented prior the evaluation process.

Abstract: The present invention is related to the use of ethylene alkanoate-alkyl acrylate bipolymers with a high randomness monomers distribution, which are synthesized by semicontinuous emulsion polymerization process, characterized because it is carried out using slow addition rate of the pre-emulsion feeding ({dot over (q)}≤0.009 kg·L−1·min−1), stabilized this last one by alkyl glycol ether type surfactants, at temperatures higher than 75° C. and with solids contents above 25 wt %, which avoids the formation of large sequences (blocks) of a same monomer. This structural characteristic gives the ethylene alkanoate-alkyl acrylate bipolymers a high efficiency as chemical agents for removal of complex water/crude oil emulsions of crude oil blends.

Abstract: This disclosure relates to an organic gel formulation composition for blocking fluids in naturally fractured carbonate reservoirs, for salinity conditions up to 31,870.50 ppm of total dissolved solids and temperatures up to 120° C., that is, for the purpose temporarily isolating areas of the reservoirs, that will be treated with chemical and radioactive products to quantify the oil remaining in them, the stability of the gel is controlled in a certain period of time, through the synergic effect of the supramolecular interaction between the components of the gel formulation. A disclosed composition may include 0.3 to 1% by weight of a copolymer of acrylamide butyl tertiary of sulfonic acid and acrylamide, and 0.12 to 0.4% by weight of phenol and from 0.18 to 0.6% by weight of hexamethylenetetramine.

Abstract: Nowadays, one of the major problems of the oil industry is the presence of large amounts of water and salts, which cannot be efficiently removed by conventional dehydrating polymers. In addition, the acid stimulation operations of petroleum wells cause the chemical degradation of demulsifiers such as polyethers and phenolic resins, reducing drastically their efficiency as water and salt removers. Based on aforementioned, a series of new copolymers has been developed, where the copolymers are combinations of an acrylic and an aminoacrylic monomer and are synthesized by semi-continuous emulsion polymerization (under starved feed conditions), which ensures both the homogeneity of the different chains as well as the randomness of the monomers distribution. The solutions of one of these random copolymers have shown an efficiency similar or superior to combinations of two or three block copolymers (formulations), when they are applied in light or heavy crude oils. The acrylic-aminoacrylic copolymers show good performance as water/oil emulsion breaker initiators, coalescence agents of water droplets and clarifiers of the remaining aqueous phase. In addition, the chemical structure of the acrylic copolymers confers resistance to degradation induced by abrupt pH changes when acid stimulation operations of wells are performed.

Abstract: Compounds and compositions are used as corrosion inhibitors for pipelines for crude oil containing water with high salt concentrations. The inhibitors are ionic liquids, imidazoles, benzotriazoles, and mixtures thereof. The composition includes two or more members of the inhibitors with a solvent. The inhibitors reduce corrosion of metallic surfaces of the pipelines containing crude oil having 0.2 and 40 wt % water, 10,000 to 70,000 ppm salt, and 9 to 600 ppm hydrogen sulfide. A synergic effect is provided by two or more different inhibitors. This synergy is derived from interactions with the metallic surface, among themselves or with the corrosive medium depending on the chain length, to inhibit the corrosion with decrease of the formulation dose. The composition can be a ternary formulation of the three families or two components of one family and a third component of a different family.

Abstract: A process is disclosed for removing fluoridated compounds from any organic medium, for example from alkylation (“alkylated”) gasoline, which can be applied at the exit of the alkylation process or inside the distillation column of the alkylation process. The process uses extractant chemical agents based on ionic liquids, of general formula C+A−, where C+ represents an organic or inorganic cation, specifically imidazolium, pyridinium, or ammonium salts, while the anion A− represents the halide-type derivatives, iron (III) salts, aluminum (III) salts, acetate, benzoate-acetates, benzoates, hexafluorophosphate, tetra-chloroborate, triflates, bis-triflates and trifluoroacetates. These ionic liquids act as extractant agents to remove fluoridated compounds from the hydrocarbon streams that are produced in the process of alkylation of isubutane with butenes, through a liquid-liquid extraction process, with a reduction of more than 80% in the content of contaminants like organofluoridated hydrocarbons.

Abstract: 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.
