Determination of the coefficient of heat transfer at the bed wall boundary of an externally heated fluidized bed
… the effect of temperature driving force and mass superficial air velocity on the coefficient of heat transfer at the bed wall of an externally heated, fluidized bed of Ottawa sand at wall temperature of 200, 400, and 600 °F , and average mass superficial air velocities of 82.5, 123.2, 170.3, and …

Oxygen Mass-Transfer in Tower Fermenters
… on mass—transfer have been studied in detail: superficial air velocity and the presence of anti-foams are shown to be the most important factors. Measurements with the oxygen electrode have also been used to estimate microbial respiration rates during work on the batch growth of the filamentous …

Study of effect of process parameters and their interaction in the flotation of UG2 ore
… Among the most important are froth height, air flow rate, depressant dosage and frother concentration. On an individual level, it is expected that an increase in froth height will result in the reduction of the mechanical entrainment of chromite due to an increase in the residence time of …

Dense-phase pneumatic transport of cohesionless solids
… coordinated with the film work. At the higher superficial air velocities (approximately 15 m/sec), the particles flow in a dilute suspension within the air stream. The pressure drop across the 70 cm section fluctuates very rapidly. For the horizontal dilute-phase flow, the mean pressure drop is …

Applicazione del processo a fanghi aerobici granulari per il trattamento di reflui petrolchimici
Aerobic granular sludge was successfully cultivated in two lab scale Granular sludge Sequencing Batch Reactors (GSBR, A and B) to remove organic matter and nitrogen from two different petrochemical wastewaters (PWs). The aim of this study was to define the best operating conditions (i.e., shear …
