13. NUMERICAL SIMULATION FOR HYDROCYCLONE DESIGNED TO HIGH OIL CONTENT APPLICATION / SIMULAÇÃO NUMÉRICA DO ESCOAMENTO EM HIDROCICLONE DESTINADO A APLICAÇÕES DE ALTO TEOR DE ÓLEO
Cyclonic separation has became more and more important during the last decades as a unit process for gas-liquid, liquid-liquid and solid-liquid separation, mostly in the Petroleum industry. The off-shore exploration¿s growth requires the development of smaller and lighter equipment. This can be achieved by cyclonic separation once centrifugal fields are sev

14. DIAGNÓSTICO DE FALHAS INCIPIENTES EM TRANSFORMADORES DE POTÊNCIA UTILIZANDO A TEORIA DA EXTENSÃO / FAULT INCIPIENT DIAGNOSIS IN POWER TRANSFORMERS USING EXTENSION THEORY
Power transformers play an important role in the power energy supply, demanding the continuous monitoring of process that could lead to operation faults, specifically in the equipment electric insulation. Methods considered in the standards IEC, IEEE and NBR7274 for dissolved gas analysis (DGA) do not provide good levels of accuracy, because there are scenar

15. GERAÇÃO DE EMULSÕES DURANTE A PRODUÇÃO DE PETRÓLEO / EMULSION GENERATION DURING OIL PRODUCTION
Emulsion formation during oil production may take place in the flow inside the reservoir or in the two-phase flow down hole in production wells, and through pipelines and valves in surface facilities. Emulsions can cause a number of operational problems such as tripping of equipment in gas-oil separations plants and high pressure drops in flow lines. Flow co

16. Causas e formas de corrosão na unidade de recuperação de enxofre da Refinaria Gabriel Passos (REGAP/PETROBRAS)
This work aims at to contribute for the determination of the mechanisms and forms of steel corrosion carbon that occurs in equipment of the Sulphur Recovery Unit (URE) of the Refinery Gabriel Passos (REGAP/PETROBRAS). The products of the refining of the oil pass for treatment processes to take care of to the specifications related to the corrosivity, percent

17. GERENCIAMENTO DA INTEGRIDADE DE EQUIPAMENTOS UTILIZANDO A INSPEÇÃO BASEADA EM RISCO / INTEGRITY MANAGEMENT THROUGH RISK BASED INSPECTION
This dissertation deals with the general concepts of risk and risk based inspection (RBI) and presents a procedure that integrates risk based inspection and fitnessfor- service tools as presented in API 581 and API 579 respectively, to manage the structural integrity of static equipments and piping subjected to a corrosion mechanism. Risk of failure is quant

18. REFINERY SCHEDULING OPTIMIZATION USING GENETIC ALGORITHMS AND COOPERATIVE COEVOLUTION / OTIMIZAÇÃO DA PROGRAMAÇÃO DA PRODUÇÃO EM REFINARIAS DE PETRÓLEO UTILIZANDO ALGORITMOS GENÉTICOS E CO-EVOLUÇÃO COOPERATIVA
This work investigates the use of Genetic Algorithms and Cooperative Coevolution in refinery scheduling optimization. Oil refineries are one of the most important examples of multiproduct continuous plants, that is, a continuous processing system that generates a number of products simultaneously. A refinery processes various crude oil types and produces a w

19. Bicos dispersores da industria do petroleo : analise bidimensional aplicando a fluido dinamica computacional
The atomizers of a petrochemical fluid catalytic cracking unit (FCC) have a main role of atomizing the gas-oil at the base of the catalytic reactor (riser). Until the beginning of the decade of 1990 the atomizers used in the units of PETROBRAS suffered pronounced erosion, that causes deficiencies which affects adversely the whole process yield. The conventio

20. Horizontal Slug Flow in a Large-Size Pipeline: Experimentation and Modeling
The knowledge of the slug flow characteristics is very important when designing pipelines and process equipment. When the intermittences typical in slug flow occurs, the fluctuations of the flow variables bring additional concern to the designer. Focusing on this subject the present work discloses the experimental data on slug flow characteristics occurring
