ABSTRACT New experimental data were measured for phase transition of the binary system CO 2 + black sesame oil. A variable volume cell was employed using static synthetic method in a temperature range 303–333 K, pressures up to 20 MPa, and mass fractions between 0.12–0.39 g/g. For > 0.39, not due pressure limitations high‐pressure used. Vapour‐liquid transitions (VLE) bubble point (BP) determined. Phase oil compared reported from literature involving similar oils. The trend behaviour all...
The need to secure public health and mitigate the environmental impact associated with massified use of respiratory protective devices (RPD) has been raising awareness for safe reuse decontaminated masks by individuals organizations. Among decontamination treatments proposed, in this work, three methods potential be adopted households organizations different sizes were analysed: contact nebulized hydrogen peroxide (H2O2); immersion commercial bleach (NaClO) (sodium hypochlorite, 0.1% p/v);...
O trabalho tem por objetivo realizar uma avaliação sistemática da influência das variáveis do processo de extração (temperatura, pressão e densidade solvente) no rendimento global extratos obtidos casca Uncaria guianensis (Unha-de-Gato) utilizando dióxido carbono estado supercrítico como solvente. Avaliaram-se duas isotermas nas temperaturas 50 60 ºC combinadas com densidades CO2 0.7, 0.8, 0.9 g/ml, pressões variando 150 a 420 bar, vazão volumétrica 3L/min. tempo foi 0,5 horas período...
O objetivo deste trabalho é determinar parâmetros de transferência massa a partir das cinéticas extração dos óleos sementes maracujá (Passiflora edulis) e polpa pupunha (Guilielma speciosa), através da avaliação modelos matemáticos Tan Liou (1989), Goto et al. (1993) Martínez al.(2003). As foram realizadas utilizando-se 400g do 20g nas condições 250 Bar 50ºC para 70°C o diferentes configurações leito. Consequentemente, foi elaborada uma base dados com os resultados obtidos comparação...
