Abstract

The present invention relates to a method of propagating genetically modified yeasts or even any other yeasts that suffer a positive Crabtree effect or any other microorganisms that use sugars for growth (glucose or equivalent glucose), wherein the feeding medium inhibits the optimal exponential growth predicted throughout the process, such a method capable of providing greater process economicity (CAPEX and OPEX), increased productivity and yield (Yx/s) and reduced CAPEX due to greater cell expansion in a single stage of reactor. Particularly, the present invention describes a process for producing second generation ethanol by using different combinations of low-cost streams existing in an integrated 2G or 1G/2G ethanol production plant, combined with the unique batch propagation strategy fed in at least two exponential feeding phases, in just one cycle, with the propagation step occurring in a single reactor.

Abstract

The present invention relates to a machine learning unsupervised method to improve results obtained in electro-facies models. In this method it is possible to subdivide profile data into different unsupervised classes interactively and intuitively based on rock data information, seeking not only to meet the need to respect profile data values, but also to represent the geological knowledge that exists in the labeled data which serves as a guide in decision making to define which classes should be subdivided or attached. In the method, the result is constructed little by little and intuitively, just like the process of analyzing an outcrop or core. Initially, profile data is used to identify the most relevant and easily separable macro characteristics, such as reservoir and non-reservoir rock. Additionally, there is the possibility of interactively subdividing or attaching classes to test scenarios and quickly validate concepts. In this sense, it is quite intuitive to start from a macro analysis and gradually identify more specific characteristics based on the geological knowledge of a specialist or what the rock data indicates, so that the method allows countless interactions to be carried out until reaching the desired result.

Abstract

The present invention relates to the coprocessing of liquid plant biomass of lignocellulosic origin and residual fractions from petroleum distillation, in which the injection of the renewable charge is carried out through the top of the coker, avoiding the problems of accelerated coking in the oven tubes and obstructions in the unit lines which inevitably occur when this type of renewable charge is coprocessed in a mixture with the main (fossil) charge. In the present invention, the renewable material is injected through the top of the reactor, in conjunction with an accelerating gas, by means of a suitable injector, so as to minimize the possibility of obstruction of the system during injection. Due to the physical and chemical characteristics of lignocellulosic charges, the addition of this type of charge through the top of the reactor could also lead to difficulties related to the possibility of obstruction of the line in the reactor inlet, since the usual top temperature inside such reactors is around 440°C. In order to overcome this technical problem, the present invention proposes using an auxiliary charging system for injecting bio-oil and a gas stream, comprising a tank, a pump and a charging injector. The injection system of the present invention promotes increased speed, cooling and improved dispersion of the renewable charge in the inlet of the reactor.

Abstract

The invention described herein proposes that the study of pressure loss in an intelligent completion valve (ICV) is carried out considering both different annular flows and the existence of an axial flow coming from an upstream zone. To study pressure losses in ICVs in detail, the CFD-based methodology (Computational Fluid Dynamics) was adopted, where the geometry of a valve can be well represented by a detailed numerical simulation mesh, which allows high precision results. The invention described herein proves that when more than one completed interval produces simultaneously, a phenomenon that we call fluid confluence occurs, and this is responsible for an additional pressure loss. When there is a confluence of fluids, the pressure loss in the valve depends on both the flow coming from the annulus and the flow coming from upstream zones. The present invention proposes that a detailed pressure loss study be carried out for each valve, considering different flows of annular and column, with fluid properties consistent with the reservoir fluid. Numerical experiments are capable of providing pressure loss values that can be reproduced later. The present invention also provides a quadratic mathematical model that can be adjusted with the data obtained in the pressure loss studies detailed above.

Abstract

The present invention addresses to a method of cleaning rock samples from oil systems, based on the use of a nanofluid, which is capable of considerably accelerating the process. The developed method associates the potential of oil solubilization by the nanofluid under the temporary action of an ultrasound system, being faster and more efficient than the method traditionally used by distillation, then described in the State of the Art. The used procedure reduces the time required for the removal of oil and salt, a critical step in the characterization process of rock samples, normally from 120 to 365 days, to 3 to 7 days, using a low toxicity aqueous-based nanofluid, which does not change the properties of the rocks.

Abstract

The present invention relates to a modular optical profiler for measuring level, oil-water interface and water content in the emulsion layer. The profiler consists of optical sensor modules for temperature and pressure measurement and can be adapted for measurement in different tanks and operating processes, since it has small dimensions, flexibility and modularity. Furthermore, the profiler uses fiber optic Bragg gratings (FBG) to measure pressure and temperature gradients in production tanks. Further, the proposed modular optical profiler has the important advantage of measurement redundancy that, associated with the fusion of measurement data using different parameters, results in robust equipment that can function in different adverse operating conditions. Another important operational advantage is the possibility of customizing the number of sensors and their positions in the tank to adapt or optimize their operation in relation to the dimensional and operational characteristics of each tank or processing unit.

Abstract

The present invention discloses a method of monitoring images, particularly images from cameras on offshore platforms, where only low-frequency events trigger alarms and high-frequency events are ignored. Preferably, it implements the Multi-scale Structural Quality Score where the compared image frames are spaced in time, for example, by a space of 1 minute, 10 minutes, 15 minutes, 30 minutes, or 60 minutes. If a quality score lower than a threshold quality score is obtained, or if the quality score obtained remains within a predetermined range for a time greater than a predetermined time limit, an alarm may be triggered. Accordingly, only events that represent a significant risk to operational and personnel safety and that persist for a certain period will trigger alarms. Consequently, spurious alarms that would be caused by low relevance events are avoided.

Abstract

The method described in the present invention pertains to the field of technologies for classifying parameters related to lithological classification, that is, the rock classification system. More specifically, it relates to a method for characterization at microscopic level of lithology that includes porosity. The proposed method enables the acquisition of data related to pore chambers and the pore throats that connect them. Once the segment identified as "porosity" is subdivided into its essential elements, in addition to the estimated quantification (areal percentage associated with the void volume of the rock), it is possible to obtain geometric data of the pore chambers and pore throats from petrographic slides that reflect the geological complexity of a rock in a sample-based manner.

Abstract

The present invention relates to a system and method for passive optical monitoring of the concentration of multiple gases and/or multiple parameters at multiple points for obtaining and monitoring the methane concentration in offshore platforms and onshore structures, and also in the fields of mining, landfills and other industrial sectors. The system consists in the sending, by a remote fibre optic unit, of a frequency-modulated light pulse (intra-pulse modulation) that is optically selected and directed at optical splitters and delay lines for various measurement points of interest, giving rise to multiple signals that interact with the methane gas in reflective sensors, that is, sensors that reflect light, returning to the remote unit a time signal from N point sensors, which is detected by a single optical receiver and the time signals of which are analysed individually by calculating the fast Fourier transform (FFT). The FFT signal thus obtained contains an amplitude A0 at the zero frequency or DC component, f0, an amplitude A1 at the same modulation frequency as the laser, f1, and an amplitude A2 at twice the original laser frequency, f2 = 2 x f1. In this way, the system makes it possible to obtain the concentrations (C) from the N sensors on the basis of the amplitudes A0, A1 and A2, by calculating the mean (M) between log(A2/A0) and log(A2/A1), that is, M = ½ × [log(A2/A0) + log(A2/A1)], and a calibration curve, where M is invariant with respect to the optical loss of the fibre optic links and depends solely on the concentration.

The panel of any one of the SPMs is connected to a wet connector of a Subsea Seismic Data Acquisition Module (SSDAM), the SSDAM in turn providing power to the seismic sensors of the SSM during the seismic data capture. At the end of the capture, the seismic sensors send the acquired data to a memory located in the SSDAM, and the connection between the panel and the connector is finally disconnected. Also disclosed are seismic data acquisition methods and a seismic survey system, for the purposes of permanent marine seismic monitoring related to SPMs. Advantageously, this methodology has the possibility of applying part of the logistics described above in reverse, so that, at the end of the seismic data acquisition campaigns or even when convenient, the telescopic-type SPMs can be removed, freeing the seabed of such items and leaving the same as it was before installation.

Abstract

Soil maps are rarely used for the elaboration of road layouts, and there are no known algorithms that incorporate soil information dynamically. The best way to incorporate this knowledge of soils is to interpret the soil maps into a derived (interpreted) map known as the “road, pipelines and operational locations aptitude map”. This study generated an innovative algorithm that incorporates soil aptitude maps for road layouts, pipeline lines and escape routes. The novelty of the algorithm is that this aptitude information (interpreted from a map of soil classes) is collated together with relief and hydrography information. Thus, it is hypothesized that, in addition to the characteristics of the relief and proximity of watercourses, the soil map can help the decision-maker to unveil regions with serious problems that increase the costs of construction and maintenance of roads, pipelines, escape routes and operating locations.

Abstract

The invention teaches a method proposing two new indices for evaluating thermal evolution in oils from different basins and organofacies. The first index is based on the distribution ratio of high molecular weight sulfur compounds, belonging to the DBE 6 (benzothiophene) and DBE 9 (dibenzothiophene) series. The second index, called TEI, was created from the profile of aromatic hydrocarbons and molecules containing N, O and S. Both parameters were obtained from the direct characterization of the oils, by using the photoionization at atmospheric pressure (APPI) technique combined with Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS).
