1. MONITORAMENTO DA COMPOSIÇÃO EM ÉSTERES DO BIODIESEL DO ÓLEO DE AMÊNDOA DA MACAÚBA (Acrocomia aculeata (Jacq.) Lodd. ex Mart.) EM CONTATO DIRETO COM O AÇO CARBONO E O AÇO CARBONO GALVANIZADO
The oil from the macaúba (Acrocomia aculeata) fruit, a native palm in Brazil, has a real potential for the industrial production of biodiesel. This report describes an experimental work devoted to monitor the chemical behavior of the fatty acid methyl esters from oil of the macaúba fruit kernel and the leaching of metal elements into the biodiesel put in c

2. Biofilm Formation and Corrosion on Carbon Steel API 5LX60 in Clayey Soil
Corrosion of buried pipelines is a matter of concern to the oil and gas industry since the time when carbon steel began to be widely used in these pipelines for the transportation of fluids. The microbial communities associated with biofilms promote modification in the surrounding environment and may accentuate the degradation of oil and gas pipelines causin

3. Numerical prediction of bed-load and surface deformation on a granular bed sheared by a turbulent boundary-layer
The entrainment of solid particles by a fluid flow is frequently found in nature and in industry. A better knowledge of this is of importance to understand the physical nature of the phenomenon and to improve industrial processes. Bed-load occurs if the shear stresses exerted by the fluid on the granular bed are bounded to some limits: a mobile granular laye

5. Análise experimental e numérica do escoamento multifásico gás-sólido em ciclones
Gas-solid are involved in various industrial processes, mainly by low power consumption for the transport of solid particles via drag a gas stream. In these cases the recovery of solid or purification of gases is promoted by cyclonic separation. Several studies on cyclones are presented in the literature from experimental studies by numerical simulation with

6. Desenvolvimento de sistema de reparo para dutos e tubulações industriais utilizando materiais compósitos de matriz polimérica / Development piping and pipeline repair system using polymeric matrix composite materials
O emprego de materiais compósitos de matriz polimérica como reparo e reforço em estruturas nas indústrias do petróleo tem se tornado uma prática industrial comum. O uso destes reforços compreende desde o recobrimento de superfícies com defeitos, passantes ou não, até o reforço estrutural. Na última década, muitos estudos foram feitos para o dese

7. MODELAGEM TRIDIMENSIONAL DE GOLFADA UNITÁRIA EM TUBULAÇÃO HORIZONTAL COM MODELO VOF (VOLUME OF FLUID) / THREE DIMENSIONAL MODELING OF A SINGLE UNIT SLUG IN A HORIZONTAL PIPELINE WITH THE VOF MODEL
Pipeline and equipment multiphase flow modeling in oil industry has become a crucial task due to the constant increasing fossil fuel demand and latest oil discovers in Brazil. Among all possible flow configurations that multiphase flow can take, the slug flow regime plays an important role due to its intermittent characteristics and its strong pressure gradi

8. Project and assembling of pneumatic transport pilot unit in diluted phase for studying the relationship between the pressure drop and the distribution of granular particles into the cross section of industrial pipes / Projeto e montagem de unidade piloto de transporte pneumatico em fase diluida para estudo da relação entre a perda de carga e a distribuição de particulas granulares na seção transversal de dutos industriais
The pneumatic transport that involves the use of air particles to move materials through pipes is a major operation in various industries and chemical processes. Typical examples are systems for the conversion of energy from coal, catalytic cracking, drying and transport of solid and fine granular. The conventional pneumatic transport is often operated in di

10. Ecogenômica de archaea e monitoramento de comunidades de procariotos redutores de sulfato: aplicações na indústria de petróleo e gás
The human activities responsible for the ambient degradation in the modern world are diverse. The industrial activities are preponderant in the question of the impact consequences for brazilian ecosystems. Amongst the human activities, the petroliferous industry in operation in Potiguar Petroliferous Basin (PPB) displays the constant risk of ambient impacts

12. A CONSERVATIVE METHOD TO ANALYSE TRANSIENT FLOW OF GASES/LIQUIDS IN PIPELINES / UM MÉTODO CONSERVATIVO PARA ANÁLISE DE TRANSIENTES DE GASES/LÍQUIDOS EM TUBULAÇÕES / UN MÉTODO CONSERVATIVO PARA ANÁLISIS DE TRANSIENTES DE GASES/LÍQUIDOS EN TUBULACIONES
The main objective of the present work is to solve numerically the flow of liquid and gases isothermal or not, in the transient regime, in industrial pipes with variable area. It also has as objective to investigate the velocity, pressure and temperature field in the presence of fluid leak in the pipe. The numerical code was implemented to solve the conserva
