Predicitng calcium carbonate scaling in tubular reaztors: a thermodynamic and kinetic model with experimental data validation

Abstract: This paper presents a thermodynamic and kinetic model for simulating calcium carbonate scaling in a tubularreactor under varying saline composition, temperature, and flow rate. Simulation results are compared withexperimental data obtained from a tubular reactor developed by the IPT and Petrobras. A mathematicalmodel based on thermodynamics and crystallization kinetics Leia mais…

High- resolution site characterization tools: application of fluorescence techniques to identify DNAPL in tropical lands

Abstract: When oil spills occur, a fraction of the oil may get trapped in soil pores or can migrate through unsaturated and saturated zones. Dense non-aqueous phase liquids (DNAPL), such as creosote, move through aquifers until complete depletion or encountering an impermeable layer. The optical image profiler (OIP) is a Leia mais…

O papel da inteligência artificial no avanço da previsão de extremos de tempo e clima: sistema inteligente de previsão de extremos climáticos

Resumo: Diante do crescimento exponencial na frequência e intensidade de extremos climáticos em todos os continentes, crescimento este decorrente do aquecimento global resultante do acúmulo de gases de efeito estufa na atmosfera, faz-se mister desenvolver a capacidade de previsão de tais extremos climáticos com maior antecedência e acurácia. Este artigo Leia mais…

Investigation of humidity and mold in a wood frame building: a case study with hygrothermal simulations and field measurements

Abstract: Moisture in buildings is a complex issue involving vapor pressure, relative humidity, and the thermal aspects of building materials. Therefore, the climate, the construction system and the layout design of dwellings have a signif-icant influence on mold growth. This study investigates indoor humidity issues in wood frame social housing Leia mais…

Evaluation of waste-energy process through the combustion and co-combustion of palm residual biomass

Abstract: The increasing demand for renewable energy in industrial and agro-industrial sectors has 17 encouraged the substitution of fossil fuels by lignocellulosic biomass in cogeneration systems. In 18 this context, the residues generated in the palm oil agroindustry – specifically palm mesocarp fiber 19 and palm empty fruit bunch fiber Leia mais…

Characterization pf relevant biomasses in the Brazilian agricultural scenario

Abstract: Agricultural biomass residues represent viable and sustainable energy alternatives, contributing to the mitigation of atmospheric emissions, rural development, and the transition to a low-carbon economy. Brazil has great potential for energy use from this residue, but to achieve this, it is necessary to understand its composition. Obtaining this information Leia mais…

Enhancing combustion properties of elephant grass and palm empty fruit bunch fiber trhrough water leaching

Abstract: Elephant grass (EG) and palm empty fruit bunch fibre (EFB) have great potential for bioenergy. However, their high content of alkaline ash, chlorine and other contaminants hinders direct combustion by promoting slagging, fouling and pollutant emissions. To address this issue, the main goal of this study was to assess Leia mais…
