The proposal includes performance indicators that seek to establish more appropriate strategies for effective institution management. It might help policy making of university-industry interaction policies

Regulação do livre acesso no transporte de gás natural à luz da ordem econômica da Constituição de 1988

In the middle of modern social changes produced by globalization and capitalism, several markets have changed. States have left the direct coordination of these markets (chiefly public utility sector in the form of monopolies), introducing regulation in order to promote competition. These changes have affected natural gas industry by promoting competition as a key factor to the development and the increase of firms in this market. The regulatory reform of natural gas industry ocurred in EUA and Europe Union and it has produced its first results. In Brazilian context, Constitutional Amendment nbr. 09 and Federal Law nbr. 9.478/97 ( Petroleum Law ) opened the natural gas market to a broad range of private economic agents and they finished the monopoly over the industry before managed by Petrobras. The new regulatory framework of Brazilian natural gas industry has designed competition as a central element to the new form of managment of business and contractual relationships of this industry. Among the regulatory instruments, open access regulation in natural gas pipelines is directed to promote competition. The questions arised about its implementation in Brazilian context are studied in the present work, in which it is discussed the constitutional rules and principles are to be applied to the open access regulation within the theme of statal regulation of economy present in constitutional economic order

Estratégia de manutenção de equipamentos elétricos em unidades offshore de produção de petróleo e gás baseada na filosofia de operações integradas.

A função Manutenção é extremamente relevante para garantir o cumprimento do planejamento da produção de óleo e gás natural de uma unidade marítima de produção, pois impacta diretamente na eficácia do processo produtivo. Quando se trata de uma instalação offshore, a manutenção passa a ser ainda mais importante, pois falhas em equipamentos e sistemas industriais podem, além de causar perdas econômicas, causar graves acidentes às pessoas e ao meio ambiente. Gerir a manutenção de uma planta industrial flutuante, localizada a 300 quilômetros da costa, como no caso daquelas localizadas nos campos do pré-sal brasileiro, é uma tarefa que requer a aplicação das técnicas mais modernas de gerenciamento de manutenção e processos de trabalho ágeis e dinâmicos para garantir o suporte técnico adequado a partir de instalações localizadas em ambientes onshore. Neste contexto, esta tese tem como objetivo avaliar e propor uma metodologia para definição da estratégia de manutenção a ser implementada em novas unidades de produção de petróleo e gás natural destinadas a operar em ambiente offshore. Esta metodologia, pautada na manutenção centrada em confiabilidade, tem como objetivo garantir que a estratégia de manutenção, além de garantir a máxima disponibilidade e eficiência dos equipamentos e sistemas, também seja compatível com a filosofia das Operações Integradas, recentemente desenvolvida pela indústria norueguesa de exploração e produção de petróleo para otimizar a produção de seus campos que já estão em fase de amadurecimento. Dessa forma, este trabalho contribuirá para que, com base na metodologia proposta para definição da estratégia de manutenção, novas plataformas de petróleo e gás natural possam operar com ainda mais segurança e eficiência, garantindo o melhor aproveitamento possível das reservas de petróleo. Este trabalho inclui uma análise de custos simplificada para os estudos de caso propostos, não fazendo parte do escopo do trabalho uma análise de custos detalhada para toda instalação.

Estudo da absorção das espécies pesadas do gás natural em octanol: efeitos da temperatura e vazão

In the oil industry, natural gas is a vital component of the world energy supply and an important source of hydrocarbons. It is one of the cleanest, safest and most relevant of all energy sources, and helps to meet the world's growing demand for clean energy in the future. With the growing share of natural gas in the Brazil energy matrix, the main purpose of its use has been the supply of electricity by thermal power generation. In the current production process, as in a Natural Gas Processing Unit (NGPU), natural gas undergoes various separation units aimed at producing liquefied natural gas and fuel gas. The latter should be specified to meet the thermal machines specifications. In the case of remote wells, the process of absorption of heavy components aims the match of fuel gas application and thereby is an alternative to increase the energy matrix. Currently, due to the high demand for this raw gas, research and development techniques aimed at adjusting natural gas are studied. Conventional methods employed today, such as physical absorption, show good results. The objective of this dissertation is to evaluate the removal of heavy components of natural gas by absorption. In this research it was used as the absorbent octyl alcohol (1-octanol). The influence of temperature (5 and 40 °C) and flowrate (25 and 50 ml/min) on the absorption process was studied. Absorption capacity expressed by the amount absorbed and kinetic parameters, expressed by the mass transfer coefficient, were evaluated. As expected from the literature, it was observed that the absorption of heavy hydrocarbon fraction is favored by lowering the temperature. Moreover, both temperature and flowrate favors mass transfer (kinetic effect). The absorption kinetics for removal of heavy components was monitored by chromatographic analysis and the experimental results demonstrated a high percentage of recovery of heavy components. Furthermore, it was observed that the use of octyl alcohol as absorbent was feasible for the requested separation process.

Impacto da Lei de Acesso à Informação: os casos da Agência Nacional de Petróleo, Gás Natural e Biocombustíveis e das agências reguladoras federais

A publicação da Lei 12.527 em 2011, a Lei de Acesso à Informação, cuja vigência se deu a partir de maio de 2012, uma vez que o texto previa 180 dias para implementação, veio ratificar a instituição da transparência como regra e do sigilo como exceção para todos os níveis e esferas da administração pública brasileira. A entrada em vigor da lei colocou o desafio de transformá-la em instrumento efetivo de apoio a um governo mais aberto e responsivo. Assim, a Lei teve repercussões importantes nas repartições públicas, quanto a novos procedimentos e desenhos institucionais para dar conta de sua amplitude e ambição. Este trabalho realiza uma análise explorativa desses desdobramentos para o primeiro ano e meio de aplicação, tanto do ponto de vista quantitativo quanto qualitativo, para a práxis cotidiana nas Agências Reguladoras Federais e na Agência Nacional do Petróleo, Gás Natural e Biocombustíveis, em particular.

Os limites constitucionais ao exercício de direito de patente e seus reflexos na indústria do petróleo, gás natural e biocombustíveis

This dissertation deals with the constitutional limits on the exercise of patent rights and its effects on the oil, natural gas and biofuels. Held with the support of ANP / PETROBRAS, It seeks to show how the law will limit the exercise of industrial property, based on a reinterpretation of private law by the constitutional development perspective . Today it is a fact that Petrobras, a Brazilian joint venture, has the latest technology in various sectors of the oil industry, and is one of the highest investments in developing new technologies. The overall objective of this thesis is to establish the relationship between the public interest of the Petroleum Industry, Natural Gas and Biofuels and constitutional limits to the free exercise of patent rights, then confirm or refute our hypothesis that Article 71 on Industrial Property Law is contrary to the existing objectives in Article 3 of the Constitution of the Federative Republic of Brazil. The research aims to examine the relevant aspects of the legal nature attributed to IPGN constitutionally confronting the constitutional limits on the free exercise of patent rights, with the purpose to outline the state of the performance limits in the regulation of the economy, in particular the application of feasibility limitations on the right of property in favor of national interest on the strategic energy industry. The aim is to confront the fundamental rights to property and economic development, against the public interest, limiting these first. As to the objectives, the research will be theoretical and descriptive and harvest of industrial property, respect the possible impact of regulatory standards and limiting the right of ownership in the oil industry. To establish how the state will mitigate the intellectual property right, we discuss, at first, a definition of public interest from the general theory of state and sovereign character in order to establish a new concept of national interest and popular interest, which will in turn the definition of our concept of public interest. In the second phase, will be addressed the issue of industrial property rights and how to will be free exercise thereof, in the constitutional sphere, infra, and demonstrating the use of industrial property rights with examples of market and IPGN . After situating the industrial property rights in the constitution and national legislation, establish their relationship with the national and regional development, will be addressed in this chapter in particular the patent law, as most usual form of intellectual property protection in IPGN. Used a study highlighting the number of patents in the area of the analyzed industry, demonstrating with hard data the importance of a sector for industrial development. The relationship between the social function of intellectual property and the constitutional objective of development was characterized to demonstrate the strategic nature of oil to Brazil in the national and international scene, and put into question the hypothesis of the research which provides that even with large investments the lack of legal certainty in the sector turns out not to have a considerable volume of investment as it could.

Modelização do despacho económico de Gás Natural

Com as variações e instabilidade dos preços do petróleo, assim como as políticas europeias para adoção de estratégias para o desenvolvimento sustentável, têm levado à procura de forma crescente de novas tecnologias e fontes de energia alternativas. Neste contexto, tem-se assistido a políticas energéticas que estimulam o aumento da produção e a utilização do gás natural, visto que é considerado uma fonte de energia limpa. O crescimento do mercado do gás natural implica um reforço significativo das redes de transporte deste combustível, quer ao nível do armazenamento e fornecimento, quer ao nível dos gasodutos e da sua gestão. O investimento em gasodutos de transporte implica grandes investimentos, que poderiam não ser remunerados da forma esperada, sendo um dos motivos para que exista em Portugal cinco distritos se veem privados deste tipo de infraestruturas. O transporte de gás natural acarreta custos elevados para os consumidores, tanto maiores quanto maior forem as quantidades de gás transacionadas e quanto maior for o percurso pelo gás natural percorrido. Assim assume especial importância a realização de um despacho de gás natural: quais as cargas que cada unidade de fornecimento de gás irá alimentar, qual a quantidade de gás natural que cada UFGs deve injetar na rede, qual o menor percurso possível para o fazer, o tipo de transporte que será utilizado? Estas questões são abordadas na presente dissertação, por forma a minimizar a função custo de transporte, diminuindo assim as perdas na rede de alta pressão e os custos de transporte que serão suportados pelos consumidores. A rede de testes adotada foi a rede nacional de transporte, constituída por 18 nós de consumos, e os tipos de transporte considerados, foram o transporte por gasoduto físico e o transporte através de gasoduto virtual – rotas de transporte rodoviário de gás natural liquefeito. Foram criados diversos cenários, baseados em períodos de inverno e verão, os diferentes cenários abrangeram de forma distinta as variáveis de forma a analisar os impactos que estas variáveis teriam no custo relativo ao transporte de gás natural. Para dar suporte ao modelo de despacho económico, foi desenvolvida uma aplicação computacional – Despacho_GN com o objetivo de despachar as quantidades de gás natural que cada UFG deveria injetar na rede, assim como apresentar os custos acumulados relativos ao transporte. Com o apoio desta aplicação foram testados diversos cenários, sendo apresentados os respectivos resultados. A metodologia elaborada para a criação de um despacho através da aplicação “Despacho_GN” demonstrou ser eficiente na obtenção das soluções, mostrando ser suficientemente rápida para realizar as simulações em poucos segundos. A dissertação proporciona uma contribuição para a exploração de problemas relacionados com o despacho de gás natural, e sugere perspectivas futuras de investigação e desenvolvimento.

Comportamento de um motor de ignição por compressão trabalhando com óleo Diesel e gás natural

A previsível escassez de petróleo aliada a uma consciência ecológica está levando pesquisadores a procurar novas fontes de energia e processos de combustão mais eficientes e menos poluentes. Entre os combustíveis menos poluentes está o gás natural, cujo consumo aumenta ano a ano. Os motores de combustão interna são transformadores de energia que têm baixa eficiência de conversão. Este trabalho avaliou um motor Diesel, bicombustível, movido a Diesel e gás natural. Nesse motor, a energia provém, basicamente, da combustão do gás natural. O Diesel tem a função de produzir o início da combustão do gás, que é o combustível principal. Assim, haverá uma substituição parcial de óleo Diesel por gás natural, aumentando o rendimento da combustão. Inicialmente, foi feito um ensaio-testemunha, somente com óleo Diesel e após foram feitos ensaios, com três repetições, para variadas proporções de óleo Diesel, gás natural e ângulos de avanço da injeção. O melhor desempenho foi obtido para 22% de óleo Diesel em relação ao máximo débito da bomba injetora e 13 L min-1 de gás natural com ângulo de avanço de injeção original (21º). Nesse caso, a potência média aumentou 14%, e o consumo específico (medido em valores monetários) diminuiu 46% em relação ao ensaio-testemunha.

REPETRO - Regime Aduaneiro Especial de Importação e Exportação de Bens Destinados à Pesquisa e Lavra de Petróleo e Gás: análise dos entraves e propostas de soluções

REPETRO, the special tax regime for importing and exporting goods for the exploration and drilling of oil and gas, aims at bringing foreign assets to Brazil enjoying a suspension or even an exemption of taxes, so that Brazilian industry may profit from about 8 billion American dollars in investments. The creation of normative devices as well as the management of the REPETRO model are under the exclusive responsibility of the Brazilian Internal Revenue Services. REPETRO was created in 1999 and is composed of the following customs treatments: importation of goods with suspension of taxes by use of the drawback special regime, suspension mode for national exporting industry; exportation with fictitious exit for the national industry; temporary admission of goods or assets used in oil exploration and production, attending to the needs of both the national and foreign market. Considering the inability of the Brazilian government in restructuring its foreign trade model so that a strong investment in technology could provide for the sector¿s needs, we must ask how we can change REPETRO to help the various companies in the oil business? The issue is very important for one of our main economic activities, though not enough studied. The energy sector has a strategic importance for the development and the economic independence of any country. The winds of globalization lead Brazil to open its economy in the last decade and the national policy for exploration and drilling (E&D) was altered. The government created a new agency dedicated to market control and energy policies, the National Agency for Oil and Biofuels (ANP). With the opening of the market, Petróleo Brasileiro S.A. - Petrobras, the Brazilian giant, lost the monopoly of the oil business. The P-50 Platform, with a capacity for 180,000 barrels per day, was imported based on REPETRO. When it began operating on April 21st, 2006, Brazil achieved self-sufficiency in oil production. The present work intends to estimate the main variables affecting the importation and exportation of goods and assets for E&D, showing how REPETRO works. We also intend to look at the results yielded by the REPETRO model for the development of the production of oil and gas in Brazil, as well as show proposals for its modernization. It has been established that even though since its implementation the REPETRO model has brought fiscal advantages through the reduction of tax costs relating to foreign commerce operations and the incentive of investments in the E&D area with the increase in the national oil production there remain the following limitations: lack of preparation and of knowledge of the model; lack of adjustement of the model to the reality of actitity of E&D of oil and gas; taxes over the pre-operational stage or investment in oil production stage; non-allowance of full access by the national industry to the supply of goods and products relating to the industrialization of goods allowed by REPETRO; other fiscal and administrative difficulties. We conclude that the REPETRO model is important for the development of the area of E&D of oil and gas, but not completely effective. It is necessary to change it or create a new model based on a new perspective of the customs treatment of the activities of exploration and production, minimizing administrative procedures relating to the operations of exportation and importation.

Avaliação da dolomita funcionalizada para remoção de H2S em gás natural

The natural gas is an alternative source of energy which is found underground in porous and permeable rocks and being associated or not to the oil. Its basic composition includes methane, other hydrocarbon and compounds such as carbon dioxide, nitrogen, sulphidric gas, mercaptans, water and solid particles. In this work, the dolomite mineral, a double carbonate of calcium and magnesium whose the chemical formula is CaMg(CO3)2, was evaluated as adsorbent material. The material was characterized by granulometric analysis, X-ray fluorescence, X-ray diffraction, thermogravimetric analysis, differential thermal analysis, specific surface area, porosity, scanning electronic microscopy and infrared spectroscopy. Then the material was functionalized with diethanolamine (dolomite+diethanolamine) and diisopropylamine (dolomite+diisopropylamine). The results indicated that the adsorbents presented appropriate physiochemical characteristics for H2S adsorption. The adsorption tests were accomplished in a system coupled to a gas chromatograph and the H2S monitoring in the output of the system was accomplished by a pulsed flame photometric detector (PFPD). The adsorbents presented a significant adsorption capacity. Among the analyzed adsorbents, the dolomite+diethanolamine presented the best capacity of adsorption. The breakthrough curves obtained proved the efficiency of this process

Estudo e implementação de algoritmos inteligentes para detecção e classificação de falhas na medição de gás natural

This master dissertation presents the study and implementation of inteligent algorithms to monitor the measurement of sensors involved in natural gas custody transfer processes. To create these algoritmhs Artificial Neural Networks are investigated because they have some particular properties, such as: learning, adaptation, prediction. A neural predictor is developed to reproduce the sensor output dynamic behavior, in such a way that its output is compared to the real sensor output. A recurrent neural network is used for this purpose, because of its ability to deal with dynamic information. The real sensor output and the estimated predictor output work as the basis for the creation of possible sensor fault detection and diagnosis strategies. Two competitive neural network architectures are investigated and their capabilities are used to classify different kinds of faults. The prediction algorithm and the fault detection classification strategies, as well as the obtained results, are presented

Acordos internacionais sobre a produção compartilhada de recursos naturais: a unitização interestatal na área do petróleo e gás sob o enfoque constitucional brasileiro

The apportionment of natural resources between sovereign States is a subject that relates many aspects of International law, as long as Constitutional Law, at the execution and application phases of international treaties that regulates the exploration of common goods. In this sense, because of their natural characteristics that creates an environment of constant migration and fixation in transboundary regions, terrestrial or maritime, the petroleum and the natural gas bound a complex juridical apparatus that can control the sovereign rights involved. This research is aim at accomplishing a study concerning the international agreements that enable the non-unilateral action, specifically the unitization treaties between sovereign States, as a manner to resolve situations related to the individualization of oil and/or gas reservoirs that go across their national borders. These agreements will be analyzed considering the international public law sources theory, bearing in mind yet the already existed experiences in this sense, not disregarding the way that this fact could affect Brazil. It will begin with an historical incursion over the unitization institute, covering its main characteristics and its formation and execution procedures, and finally it will address the Brazilian legal system and the comparative law threats the institute. The clauses of these relevant agreements will be analyzed in details, concerning its particularities and its contents. Because these agreements are international obligatory rules of law, it is indispensable that they are considered under the auspices of the international law system, focusing their nature and the subjects of international law and establishing them as sources of the international law, analyzing them, then, as international rules and the applicable law to these juridical relations, the conventional established, the consolidated international custom and the applicable International Law principles, appearing the State s responsibility as an important subject for the verification of the acts lawful practiced by States. The analysis of the apportionment of these natural resources ends with the individualization of possible exploitable marine oil fields located between the exclusive economic zone and the continental platform ends and the region administrated by the International Seabed Authority. At last, the Brazilian constitutional system appears as the mechanism of integration, application and execution of the international unitization agreements in Brazil, detaching the format and the proceedings that the international treaties take to acquire validity at the national legal system, passing through the treaties interpretation and the applicable constitutional principles, coming to its application in Brazil, considering the existing constitutional peculiarities and the role played by the National Agency of Petroleum, Natural Gas and bio-fuel ANP
