The present invention relates to a synthetic-silica catalyst used in a heterogeneous catalysis method for the effective conversion of residual glycerin resulting from the production of biodiesel into formic acid with high selectivity and stability, in a continuous-flow reaction. It should be noted that products with high added value are formed with the mere presence of an oxidizing agent, including without a catalyst. In this case, the conversion of the residual glycerin occurs by homogeneous catalysis, by the action of the components left over from the synthesis of the biodiesel, with the formation of major components, such as formic acid, cyclic ethers and diglycerol, in continuous-flow and reflux reactions. The reaction can also be brought about by adding sodium salts to the process of homogeneous catalytic conversion of the commercial glycerin. The process developed in the present invention reuses the residual glycerin without the need for purification before its transformation into products of high added value and renewable origin, enhancing the usefulness and potential of the invention.

The present invention relates to a thermal insulation blanket for undersea lines designed to help keep temperatures above the desired minimum in the related projects, since the fluids transported therein tend to lose heat to the environment. The invention resolves problems such as the formation of paraffins or incrustations, increased viscosity of the oil and hydrate formation, inter alia. The invention should be used at greater depths (where the external temperature is lower) and near to the fluid source, where the fluid temperature is greatest, and where the potential heat exchange is most intense on account of the greater temperature difference. The blanket then keeps the water heated by the line in the vicinity of the line, providing additional insulation. Additionally, the blanket is installed longitudinally on the related lines by unrolling (to facilitate installation).

The present invention relates to a process for the conversion of plant oils, animal fats, waste food oils and carboxylic acids into renewable liquid fuels, such as bio-naphtha, bioQAV and renewable diesel, for use in combination with fossil fuels. The process is composed of two steps: hydrotreatment and hydrocracking. The effluent from the hydrotreatment step contains aromatics, olefins and compounds resulting from the polymerization of esters and acids. This is due to the use of partially reduced catalysts without the injection of a sulfiding agent and allows for the production of a bioQAV of suitable quality for use in combination with fossil kerosene. Concurrently, the process generates, in addition to products in the distillation range of naphtha, kerosene and diesel, high-molecular-weight linear paraffins (up to 40 carbon atoms).

The present invention applies, in particular, to third-stage cyclone systems, equipment normally used in conjunction with fourth-stage cyclones to reduce the concentration of catalyst particles in flue gases of fluid catalytic cracking (FCC) units. The invention relates to a method in which the bleed stream from the third-stage cyclone vessel is drawn continuously through the top of the third-stage vessel, using the extensive length of this vessel to incorporate a natural separation step, in which the particles in this stream come away from the gas ascending in the vessel at low speed and return to the bottom of the vessel. The material collected by the third-stage cyclones accumulates in the cone of the vessel and is removed at regular intervals. This method is intended to increase the overall separation efficiency of the system, and is a low-cost solution compared to the use of full blocking filters.

The present invention relates to a process for producing aromatic compounds from streams containing straight chains of 5-18 carbon atoms of fossil or renewable origin and use within the field of catalytic cracking aiming for regenerator operation at a much lower temperature of between 480ºC and 620ºC, preferably at a temperature of between 500ºC and 600ºC. The coked catalyst generated by cracking light streams with low delta coke generation potential can be subjected to combustion at a lower temperature. The regeneration temperature should be at least 40°C and no more than 100°C higher than the reaction temperature, maintaining high catalyst circulation to maintain the energy balance in the reaction zone. The minimum regeneration temperature can be ensured by installing a furnace for preheating air before it enters the regenerator and passes through the air distributor inside the regenerator. The catalyst used should contain zeolite with pores of intermediate size. Such conditions significantly favour the production of aromatics and the octane rating of the naphtha produced.

The invention relates to a concentric mandrel and hanger, that uses the same gas-lift valve as used in a side-pocket mandrel. The proposed application of the invention is for wells with very low static pressure that operate by intermittent gas lift, making production on these wells viable. The development of a concentric mandrel and the respective macaroni hanger allows for the use of an insert accumulation chamber, and also makes it possible for the gas-lift valve to be replaced with a slick line unit, thus avoiding rig interventions, which are more costly and time-consuming.

The present invention relates to a process for the conversion of plant oils, animal fats, waste food oils and carboxylic acids into renewable liquid fuels, such as bio-naphtha, bioQAV and renewable diesel, for use in combination with fossil fuels. The process is composed of two steps: hydrotreatment and hydrocracking. The effluent from the hydrotreatment step contains aromatics, olefins and compounds resulting from the polymerization of esters and acids. This is due to the use of partially reduced catalysts without the injection of a sulfiding agent and allows for the production of bioQAV of suitable quality for use in combination with fossil kerosene. Concurrently, the process generates, in addition to products in the distillation range of naphtha, kerosene and diesel, high molecular weight linear paraffins (up to 40 carbon atoms).

The invention uses the principle of the pneumatic turbine and a cooling system for the entire welding torch, in which the gas used in the welding process, or even the compressed air, enters through a conduit in the axial direction to the consumable, thus moving a turbine, which in turn moves a nozzle and a nozzle holder. The welding torch can be used for extended periods of time at 100% duty cycle, in NEMA class I welding machines, since it is water-cooled. In addition, the torch can be used on any welding source made by any manufacturer, whether the machine is new or very old, since the euro standard (adopted) is the same. This means that there is no need to acquire a new welding machine, but simply a torch. In construction and assembly environments, such as welding risers, refineries, joint welding, cladding, and processes aimed at constructing a part using just one welding consumable, the use of said torch will provide significant savings in terms of reduced time and cost. This torch can also be used on any existing welding device, within the aforementioned processes.

The present invention relates to a method for identifying operational problems based on the hydrodynamic characterization of the well/gas lift and production line assembly, by means of injecting alcohol, preferably ethanol, into the gas lift line. The detection of the passage and return of the alcohol is carried out by direct analysis of the information about the process variables (pressure and temperature at the bottom of the well, at the Christmas tree and at the surface, gas or liquid flow meters, etc.). Preferably, said detection must also be confirmed by measuring the concentration of the returning alcohol, either by sequential collection of samples of the liquid produced by the well and subsequent physical and chemical analysis in a laboratory, or by an online measuring instrument installed to this end. A practical procedure for collecting samples has been developed for application in conjunction with this invention. Chemical analysis methods for determining small quantities of water in alcohol are known from the prior art, but the reverse is not found. Procedures for analysing small quantities of alcohol in water have thus been specially developed for application in conjunction with this invention.

The present invention proposes a subsea arrangement in which the lines that interconnect the production wells to a given SPU (stationary production unit) are arranged so as to allow a given group of production wells to be interconnected, at the same time, to more than one SPU, by means of separate configurations. The proposed solution can be applied in subsea oil and gas production fields composed of (or with provision for) more than one SPU, with provision for injecting water and/or gas, in carbonate or non-carbonate reservoirs. This provides advantages in the event of scheduled or unscheduled shutdowns of one of the SPUs, in addition to improved distribution of the total production from the wells, and also the application of wider strategies to combat hydrates and other flow assurance complications.

The aim of the present invention is to use numerical weather modeling to obtain temperature forecasts for the municipalities in a given region and then to use the number of consumers to give greater weight to the temperature in the municipalities where there are more consumers. Thus, a temperature index is obtained which is representative of the demand for electrical energy in the region under analysis, said index being known as the Mean Temperature Weighted by the Number of Consumers (MTWNC). Using this index and historical load data, second-order polynomial regressions are made to find the relationship between the load and the MTWNC. These regressions are made for each hour of weekdays, Saturdays, Sundays and public holidays, for each month of the year. With this information it is possible to forecast the load and, thus, to provide for better management of energy resources and greater sustainability in the electrical energy sector.

During meetings for planning operations for scale removal and scale inhibitor squeeze treatment in wells, the possibility of the manifold being partially incrusted with scale was raised considering the more critical mixture of water produced. The proposed solution is a method of treatment for removing scale from a manifold. Said method uses the geothermal heating of the exploration reservoir to heat a chemical removal solution (50). Heating is required to ensure the temperature is in a range that is also suitable for carrying out the removal reaction, since the distance that the solution travels to the manifold (20) and the low temperature of the underwater environment make the reaction occur inefficiently, as in the case of pre-salt.

The present invention is used to form the structure of a system that operates inside ducts. It can be used in a robotic system in the form of a string to move tools inside pipes or ducts with small diameters. It avoids the need for costly commercial connectors with a limited variety of connections. The proposed solution is that of splitting/dividing the electronic or hydraulic components into pressure vessel modules, thus making it necessary to provide suitable means of interconnection between said modules by means of an elastomeric conduit. Each module has a heat exchanger (heat sink) system to remove the heat generated by the electronic equipment installed therein. The product of the invention has a sufficient degree of freedom to move in subsea ducts and pipes, in which the hydrostatic pressure is extremely high.
