Optimization of Ultrasound-Assisted Extraction of Phenolic Compounds from Romanian Blackthorn (<i>Prunus spinosa</i> L.) Fruits by Ana-Maria Drăghici-Popa, Oana Cristina Pârvulescu, Raluca Stan, Ana-Maria Brezoiu

“…Six process factors, including solvent/plant material ratio (<i>R_LS</i> = 4.95–15.1 cm³/g), ethanol concentration in the extraction solvent (<i>c_et</i> = 16.4–83.6%), extraction temperature (<i>t</i> = 30–70 °C), pH of the solvent (<i>pH</i> = 2–7), amplitude of the ultrasonic probe (<i>A</i> = 30–70%), and extraction time (<i>τ</i> = 5–15 min), were screened and optimized based on a Plackett–Burman design (PBD) and a central composite design (CCD). Statistical analysis indicated that <i>R_LS</i>, <i>c_et</i>, and <i>t</i> significantly affected the process response variables in terms of total phenolic content (<i>TPC</i>), total anthocyanin content (<i>TAC</i>), and antioxidant capacity (<i>AC</i>). …”

Optimization of the homogeneous rhodium-catalyzed methanol carbonylation reactor to reduce CO2 emissions by A.H. Oudi, R. Golhosseini

“…In this paper, the steady-state homogeneous rhodium-catalyzed methanol carbonylation reactor is simulated using Aspen HysysV.9 software, by comparing the simulation results with industrial information, a mean relative error (excluding methanol) of 4.8% was obtained, which indicates the high accuracy of the simulation. The central composite design (CCD) and genetic algorithm (GA) with the aid of a simplified process simulation were used to estimate the effect of individual variables (liquid level, the temperature of the catalyst-rich recycle stream, the mole ratio of CO to methanol (MeOH) in the feed, and flow rate of dilute acid stream) and their mutual interactions to reduce CO2 emissions. …”
