The study of two-phase fluid flow behavior in hydraulic structures such as pressurized flow tunnels, culverts, sewer pipes, junctions and other similar conduits is of great importance. A two-phase mixture flowing in a pipe can exhibit several interfacial geometries such as bubbles, slugs or films, depending on the fluid and hydrodynamic properties of flow. The main variables, giving rise to a v...

• Three biorefineries are modelled, focusing on the rutin extraction from asparagus waste. The environmentally compared with Life Cycle Assessment methodology. pressurized liquid-based scenario reports best environmental profile. Energy consumption is responsible for largest contributions to burdens. Sensitivity analysis performed considering different allocation and agents. Rutin a flavonol gl...

The performances of ionic liquid (1-hexyl-3-methylimidazolium-bis(trifluoromethylsulfonyl)imide, IL/CPE) and iron phthalocyanine (IP/CPE) modified carbon paste electrodes in electroanalytical determinations of rutin were evaluated and compared to the performance of unmodified carbon paste electrode (CPE). Cyclic voltammetry (CV), differential pulse voltammetry (DPV), differential pulse adsorpti...

Our earlier work showed that the stability of the bioactive compounds gastrodin (GA) and vanillyl alcohol (VA) in Gastrodia elata Blume behaved differently with varying compositions of water-ethanol using pressurized liquid extraction (PLE) at room temperature. To have a better understanding of the extraction process of these thermally labile compounds under elevated temperature conditions, pre...

Extractions of a polycyclic aromatic hydrocarbon (PAH)-contaminated soil from a former manufactured gas plant site were performed with a Soxhlet apparatus (18 h), by pressurized liquid extraction (PLE) (50 min at 100 degrees C), supercritical fluid extraction (SFE) (1 h at 150 degrees C with pure CO2), and subcritical water (1 h at 250 degrees C, or 30 min at 300 degrees C). Although minor diff...

This study aimed to optimize pressurized liquid extraction (PLE) of phenolic compounds from the brown seaweed Fucus vesiculosus obtain extract with high yield, rich in compounds, good radical scavenging, and metal chelating ability. The was optimized a Box–Behnken design experiment response surface tool. Optimal condition found at 137.18 °C, 58.65% v/v ethanol water 4.68 min time which resulted...

The valorization of agro-industrial waste streams and residues for the production antioxidant compounds is a good strategy circular economy approaches. However, to demonstrate its suitability operational feasibility, it necessary develop environmental assessments ensure effectiveness strategy. In this sense, large-scale simulation has been developed, obtaining ten different scenarios in which b...
