1. Performance of the INCONEL 625 alloy weld overlay obtained by FCAW process
ABSTRACT Nickel-based weld overlays (cladding) are commonly used in oil & gas industry to extend the life of equipment under corrosive environment, as it improves the corrosion resistance without a significant increase in the manufacturing cost, when compared to a full nickel-based alloy equipment. Although there are extensive literature involving overlays a

3. Appliance of a high pressure semi-batch reactor: supercritical transesterification of soybean oil using methanol
Abstract This work presents the results of a supercritical transesterification process of soybean oil using methanol, performed in a laboratory high pressure semi-batch reactor. A full description of the equipment and a standard operating procedure are also provided. Since fossil fuels are not renewable, biofuels such biodiesel, have gained attention over t

4. Caracterización del comportamiento frente a la corrosión en soldaduras de recargue de aceros inoxidables superdúplex
ABSTRACT Superduplex stainless steels have a dual structure constituted approximately by 50% of ferrite and 50 % of austenite. This fact produces a good combination of mechanical properties and corrosion resistance. Thanks to these features their use is growing, mainly in the industries of paper, chemical, gas and oil. Surfacing welding is used for the manuf

5. Química Sem Fronteiras: o desafio da energia
Coal, natural gas and petroleum-based liquid fuels are still the most widely used energy sources in modern society. The current scenario contrasts with the foreseen shortage of petroleum that was spread out in the beginning of the XXI century, when the concept of "energy security" emerged as an urgent agenda to ensure a good balance between energy supply and

6. DEPLOYMENT OF METHOD FOR ANALYSIS OF STABLE CARBON ISOTOPES (N-ALKANES C1-C5) IN GAS SAMPLES AT LOW CONCENTRATIONS / IMPLANTAÇÃO DE MÉTODO PARA ANÁLISE DE ISÓTOPOS ESTÁVEIS DE CARBONO (N-ALCANOS C1-C5) EM GASES A BAIXAS CONCENTRAÇÕES
The concentration and isotopic composition of n-alkanes C1-C5 has revealed as a powerful tool for interpretation of interesting processes in the oil exploration industry, studies of global climate change, oil biodegradation and carbon cycle elucidation. In this context, studies about methane analysis have been distinguished and multiplied due to the importan

7. Effect of high energy milling on the microstruture and properties of wc-ni composite
Hard metal is a composite material used in several areas of machining, mining and construction. It can be applied directly on oil and gas drilling equipment components. The main objective of this work was to apply a high energy milling technique to produce the WC-Ni composite and study the effects of milling time in the material properties. The milling of ha

8. Sistema especialista fuzzy para dimensionamento de bombeio mecânico
Despite the emergence of other forms of artificial lift, sucker rod pumping systems remains hegemonic because of its flexibility of operation and lower investment cost compared to other lifting techniques developed. A successful rod pumping sizing necessarily passes through the supply of estimated flow and the controlled wear of pumping equipment used in the

12. Performance prediction and validation of equilibrium modeling for gasification of cashew nut shell char
Cashew nut shell, a waste product obtained during deshelling of cashew kernels, had in the past been deemed unfit as a fuel for gasification owing to its high occluded oil content. The oil, a source of natural phenol, oozes upon gasification, thereby clogging the gasifier throat, downstream equipment and associated utilities with oil, resulting in ineffectiv
