A sinfonia do sagrado em Castro Alves: (Deus, Eros e mãe em Os escravos)
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-Graduação em Literatura.No presente trabalho realiza-se uma leitura intertextual entre a Bíblia e Os escravos, coletânea de poemas de teor abolicionista do poeta romântico Antônio Frederico de Castro Alves (1847-1871), objetivando demonstrar que os textos poéticos arquitetam-se na desconstrução e reconstrução dos textos bíblicos. A leitura dos poemas centra-se nos personagens: Deus, Eros e Mãe, os quais conformam uma trindade poética/sagrada. A pesquisa divide-se em três movimentos: Prelúdios do sagrado no Romantismo, Tríade melódica e À guisa de coda: trindade poética. No primeiro efetuam-se algumas aproximações ao conceito do sagrado e aos Romantismos francês e brasileiro. O seguinte corresponde à leitura das composições, através das linhas melódicas: A dualidade de Deus, A ambivalência de Eros e O duplo calvário da Mãe escrava. E no último movimento amalgamam-se as inter-relações entre a trindade cristã e poética e os dramas bíblico e poético

Reactive Orange 16 dye degradation in anaerobic and aerobic MBBR coupled with ozonation: addressing pathways and performance
No full textIn this study, two treatment routes were investigated for degradation of the azo dye Reactive Orange 16 (RO16): biodegradation in an anaerobic MBBR (R1) and ozonation followed by biological treatment in an aerobic MBBR (R2). Along with the dye, glucose and nutrients were supplemented to the influent fed to R1 as carbon co-substrate and nitrogen source, respectively. In R1, maximum color removal of 61 ± 18% was achieved for 5 mg l−1 of dye, hydraulic retention time of 12 h and influent COD of 800 mg l−1. Moreover, RO16 biodegradation was limited by carbon source (glucose) and attached solids concentrations. Batch tests revealed that anaerobic biodegradation of the dye and glucose followed second-order kinetics and RO16 degradation constant increased as the initial COD was reduced. Considering the relatively low color removal achieved anaerobically, dye solutions (100 to 500 mg l−1) were ozonated, enabling fast discoloration of at least 97% within 20 min for the highest dye concentration. However, the low COD (50–75%) and TOC (35–40%) removals achieved indicate that only partial mineralization occurred. RO16 (500 mg l−1) ozonation products were identified, and a degradation pathway was proposed. Subsequently, the ozonated solutions were supplemented with glucose and nutrients and fed to R2. COD removal decreased considerably (from 92 to 81%) when ozonated solutions with original dye concentration of 500 mg l−1 were fed to R2, but ammonium removal remained fairly stable. Three compounds identified before biological treatment were not found in R2 effluent, suggesting that they were biodegraded

Triethylene glycol recovery by an energetically intensified thermosyphon-assisted falling film distillation unit: Experimental assessment on a pilot-scale unit and in-silico comparison with a conventional column from natural gas processing
No full textFacing the emerging needs for energy-enhanced separation units, this work evaluated the triethylene glycol (TEG) regeneration, used as a dehydrating agent of natural gas from wells, by a novel thermosyphon-assisted falling film distillation technology, called Destubcal. The pilot-scale device has an innovative heat supply through a two-phase closed thermosyphon, which ensures a uniform energy distribution along the entire distillation tube. Based on current operating data from industrial water-rich TEG streams, different operating conditions were performed in the pilot-scale unit. The best recovery ratio (99.0%) was obtained with an evaporator temperature of 180 °C and a feed flow rate of 15 L/h. However, in order to maximize the bottom TEG composition, the best experimental condition achieved was 17 L/h and bottom temperature of 152.07 °C, due to an evaporator temperature of 170 °C. As a result, the Destubcal unit saved around 38.4% in energy requirement and reduced 49% the column height when compared to a conventional distillation column for the same recovery degree. Therefore, the proposed Destubcal technology can be considered a feasible alternative as recovery column for TEG regeneration in natural gas beneficiation units, with advantages of reduced dimensions and energy-saving operation
