3. Comparação de diferentes abordagens para avaliação da incerteza na cromatografia gasosa do gás natural
The evaluation of uncertainty associated with an analytic result is an essential part of the measurement process. Recently, several approaches to evaluate the uncertainty in measurement have been developed. Here, the gas chromatography assay uncertainty for natural gas is compared by some of these approaches: the guide to the expression of uncertainty in mea

6. RemoÃÃo de Ãcidos naftÃnicos presentes na mistura modelo de querosene de aviaÃÃo utilizando adsorventes tipo perovsquitas modificadas
In this work were prepared adsorbents of type perovsquitas La1-xMgxNiO3, where x = 0, 0.25, 0.5, 0.75, 1.0. The addition of magnesium resulted in increased basicity of the material and consequently the affinity of the acids. The adsorbents prepared materials were characterized by atomic absorption espectrofometria (AA), X-ray diffraction (XRD) measurement of

11. Estudo de um processo de combustÃo de gÃs totalflex para calcinaÃÃo da Gipsita em regiÃes remotas
The industrial plaster production (CaSO4.1/2H2O) in Brazil is carried through by the method of dehydration (calcination) of natural crude gypsum (CaSO4.2H2O), using heat of burning essentially of solid fuels (firewood, oil coke) and liquids (oil BPF, alternative oil). Constant increase in the price of the energy matrix has motivated the calcinadoras to searc
