The present invention addresses to equipment for collecting flexible pipes without the use of special vessels, using less costly resources and which are not committed to not damaging such equipment during handling, since it is applied to pipes at the end of their useful life or that are already damaged. These types of pipes represent a major liability for some oil industry operators. The technology to be used, in phases of demobilization of fields or even for collecting pipes with no prospect of use, uses vessels with minimal adaptations that rely on the presence of collecting/launching wheels with a much smaller diameter when compared to the wheels used in conventional vessels or, alternatively, the launch of a special collection coil with its own traction means to make it possible to wind the abandoned pipes, in the same place where they are launched, with subsequent collection of the set and transshipment to the vessel itself.

The present invention discloses a pig with improvement in the suspension and centralization system, allowing it to behave properly in any diameter within a design range. The seals in the shape of petals and overlapping discs, responsible for the pressure differential that causes displacement of the pig inside the pipe, were designed to close gradually when necessary, until reaching the minimum internal diameter of the pipe. In this configuration, the face of the seals normally generates a lot of friction with the inner wall of the pipe, making it difficult to move. Metal wafers (11) were developed and applied to the seals to reduce friction. A coupling element (4) was also developed to interconnect the different modules of the pig allowing wide movement of the pig inside the pipe, facilitating its passage by sharp curves and inside the equipment. The pig has petal and disk type seals, mechanical centralization and cleaning module (5) and interconnecting tubes (4).

The present invention addresses to a blanket for thermal insulation of submarine pipelines to favor the maintenance of temperatures above the desired minimum in the respective designs, since the fluids internally transported tend to lose heat to the environment. It solves problems that occur with the formation of paraffins or scales, the increase in oil viscosity and the formation of hydrate, among others. The invention must be launched at greater depths (where the external temperature is lower) and close to the origin of the fluids, where these will have the maximum temperature and, as this variation will be maximum, the thermal exchange potential will be more intense. The blanket then keeps the water heated by the pipeline confined to the surroundings thereof, acting as additional insulation. In addition, it is installed longitudinally on the pipelines in which it operates, by being unwound (to facilitate installation).

The present invention relates to a process for converting vegetable oils, animal fats, residual edible oils and carboxylic acids into renewable liquid fuels, such as bionaphtha, bioJET-A1 and renewable diesel, for use in a mixture with fossil fuels. The process consists of two steps: hydrotreating and hydrocracking. The effluent from the hydrotreatment step presents aromatics, olefins and compounds resulting from the polymerization of esters and acids in its composition. This fact occurs due to the use of partially reduced catalysts and without injection of sulfide agent and allows obtaining a bioJET-A1 with adequate quality for use in a mixture with fossil kerosene. At the same time, the process generates, in addition to products in the distillation range of naphtha, kerosene and diesel, high molecular weight linear paraffins (with up to 40 carbon atoms).

The present invention relates to the direct use by addition of drilling gravels residue from the oil exploration and production activities in the formulation of culture medium of unicellular organisms, increasing its growth rates, intensifying the CO2 biofixation, and generating value to this residue from of productivity gains expected by autotroph and mixotroph organisms (cyanobacteria, microalgae and macroalgae), as well as the production of bioproducts that can be generated through the concept currently described in the literature as biorefining. Algae are cultured using drilling gravel suspended in the culture medium together with the ability to grow by absorbing CO2. Mechanisms used by algae in soils and marine environments to tolerate salinity, sodicity and contamination of petroleum hydrocarbons provides wide adaptation to these conditions of abiotic stress and enables the destination without environmental impact, constituting a satisfactory solution for the destination of the gravel for oil exploration and production.

The present invention addresses to a process for the production of aromatic compounds from streams containing linear chains with 5 to 18 carbon atoms, of fossil or renewable origin, and application in the field of catalytic cracking aiming at a regenerator operation at much lower temperature, between 480° C. and 620° C., preferably the temperature should be between 500° C. and 600° C. The coked catalyst generated by the cracking of light streams with low potential for delta coke generation can have the combustion effected at a lower temperature. The regeneration temperature must be at least 40° C. and at most 100° C. higher than the reaction temperature, keeping the catalyst circulation high to maintain the energy balance in the reaction section. The minimum regeneration temperature can be ensured by installing an air preheating furnace before entering the regenerator and passing through the air distributor inside the regenerator. The used catalyst must contain zeolite with pores of intermediate size. Such conditions greatly favor the production of aromatics and the octane rating of the produced naphtha.

The present invention addresses to the use of a viscous fluid in continuous pumping to contain the saline dissolution in a homogeneous way (not limited to just one type of evaporite), highlighting the results of seawater with viscosifiers, due to its simplicity, and that does not have the same impact on the logistical chain as a brine supply. The increase in fluid viscosity limits the diffusion of salt into the medium and thus better contains the dissolution of the well walls, while also promoting a laminar flow regime in the annulus of the well, variables desired to achieve the quality of the operation of cementation. The employment of viscous fluid concentrates allows “on the fly” dilutions with the in-line seawater fraction mixture. The technique can also employ solutions of pre-dispersed viscosifying additives which, when added to seawater, result in a substantial increase in the volume of drilling fluid produced, no longer limited by the unit tank capacity. This allows drilling large extensions of salt. The low salinity viscous fluid is used in drilling operations without fluid return to the drilling rig (riserless) in the presence of a predominantly saline formation, aiming at preserving the phase diameter and improve well construction conditions.

The present invention aims at developing a robot for applying coating in regions called “difficult access areas” of offshore platforms and ships, such as curved, vertical surfaces, or surfaces with negative inclination angles. The design concept was developed based on a low-weight painting system, integrated into a vehicle with magnetic shoes (104), which produces a constant magnetic force on the metallic surface, capable of guaranteeing the support of the vehicle in the different areas of application. The floating magnetic system aims at ensuring that the wheels (102) have the necessary friction for the vehicle to move. The use of the equipment allows greater productivity, with agility and speed in the application of coatings, reduction of coating losses during the process, repeatability and guarantee of the thickness of the applied layer, in addition to allowing the application of the coating on vertical surfaces, with negative inclinations or curves, without the need for access using scaffolding, dispensing with scaffolding assembly and disassembly services and the use of ropes by professionals for work on the sea, with the consequent reduction in the number of workers on the sea and the reduction of exposure of the man in unhealthy environments.

The present invention addresses to the production of an organomineral fertilizer consisting of a mineral matrix, drilling gravel and an organic matrix, algae biomass. Algae are cultivated using drilling gravel suspended in the culture medium together with their ability to grow by absorbing CO2, and, in the case of cyanobacteria, they fix atmospheric nitrogen in their biomass. The gravel provides a set of additional nutrients present in its composition to the conventional nutritional chemical compounds for algae. In this way, the gravel can be mixed with the culture medium in the cultivation of algae, generating the organic matrix to be formulated and commercialized in the national and international agricultural market as an organomineral fertilizer, and, in the case originating from the organic matrix of cyanobacteria, there is the enrichment with nitrogen obtained biologically, without the high energy expenditure typical of traditional synthetic nitrogen fertilizers. In this way, the present invention enables the disposal with a minimum of environmental impact and constitutes a satisfactory solution for the disposal of gravel for oil E&P.

This has been implemented and automated in the form of a computational algorithm and applied in the case study of an actual Production System using Marlim II simulator. For all four multiphase flow correlation sets considered, the adjustments followed each other stably, converging after a few iterations. At the end of the activity, the four sets were found to perform better than the best unadjusted set of correlations. In addition, the method provides consistent results, which is an advantage over the manual adjustment method.

Accordingly, the present invention has drastically reduced the time required for optimizing the adjustment factors of flow models and has improved quality of the adjusted model as compared to the final model obtained with manual adjustment. By better quality of the model is meant that the simulated results are closer to the measured results, that is, the model is more capable of representing the flow dynamics verified in the field. In cases with a high number of operating spots in the real system, reduction in the time required by the activity is even more significant.

After metathesis, the reactor effluent is conveyed to the separation and purification section, in which a 1-decene stream (99% m/m), a C11-C14 olefin stream (99% m/m) and a methyl ester or C10-C14 carboxylic acid stream are obtained and conveyed for coprocessing together with aviation kerosene of fossil origin in an existing hydroprocessing unit. An excess of light olefins is admitted at the input, and the unreacted portion is separated and returned to the metathesis section. A small amount of compounds of higher molecular weight is also formed, as as result of autometathesis reactions, which is separated and incinerated or used as fuel for furnaces or boilers to generate energy. The saturated FAME stream (stearate, palmitate and methyl) in the load can be used for coprocessing (up to acceptable levels) or commercialised in the form of biodiesel.

The present invention relates to a method comprising a selective hydrogenation step of vegetable oil derivatives that are mixed with light olefins and conveyed to the metathesis section, wherein the renewable carbon content of the olefins and aviation biokeresone depends on the type of origin of the light olefin stream. After metathesis, the reactor effluent is conveyed to the separation and purification section, in which a 1-decene stream (99% m/m), a C11-C14 olefin stream (99% m/m) and a methyl ester or C10-C14 carboxylic acid stream are obtained and conveyed for coprocessing together with aviation kerosene of fossil origin in an existing hydroprocessing unit. An excess of light olefins is admitted at the input, and the unreacted portion is separated and returned to the metathesis section. A small amount of compounds of higher molecular weight is also formed, as as result of autometathesis reactions, which is separated and incinerated or used as fuel for furnaces or boilers to generate energy. The saturated FAME stream (stearate, palmitate and methyl) in the load can be used for coprocessing (up to acceptable levels) or commercialised in the form of biodiesel.

The present invention addresses to a predictive method that determines the favorability of a certain list of oils for the production of oil asphalt cement (OAC), according to the requirements of the Brazilian asphalt specification of the ANP. The method was developed using an artificial intelligence algorithm, based on thousands of industrial data collected, by means of queries in BI, during the OAC campaigns of the producing refineries of the system. With a very high predictive capacity, the method is able to determine the probability of a given list of oils producing asphalt, considering both the fundamental properties of the oils that compose the same, as well as operational aspects and production route, since it was calibrated with industrial data from OAC campaigns in real magnitude. Such a model can be implanted in a web application and in an electronic spreadsheet.

The present invention refers to a system comprising microfluidic devices of extraction, capacitance analysis, together with the smartphone-controlled potentiostat, consisting of a portable system that can be applied on offshore platforms and offering an analytical procedure that requires low levels of samples and chemical ingredients. In addition, the assembly provides the in loco, fast analysis of species having fouling features with high analytical frequency. The ability to carry out these analyzes in low BSW oils represents a strong analytical improvement view of the technical difficulties observed in traditional methods that use liquid-liquid extraction. Thus, the possibility of quickly predicting the ionic composition profile of these water samples becomes a strategy for monitoring, control and decision-making actions in the production chain, making it possible to establish more appropriate fouling inhibition strategies, enabling more proactive actions rather than reactive ones to be taken by the operator. Therefore, unscheduled production stops caused by fouling in the production system are prevented.
