Finally, the high mass transfer potential of BTFs was confirmed by estimating the mass transfer capacity under varied operating conditions.
Four aromatic hydrocarbons were baseline separated within 3 min, fully demonstrating the fast mass transfer capacity of the new material.
The main advantages are the low power consumption (53 W/m3) and the high mass transfer capacity (0.007 1/s).
Simulations allow us demonstrating that to increase the productivity of raceway reactors it is recommendable to reduce the water depth into the cultures and to increase the mass transfer capacity of the entire reactor.
Also, the problem of sensitivity of the enzymes to oxygen can be minimized by using a photobioreactor with high mass transfer capacity so that the generated oxygen can be simultaneously and efficiently removed from the reactor.
The pressure gradient, total liquid hold-up and mass transfer capacity are correlated by dimensional interpolation formulas, as a function of the mass velocities of the liquid and the gas through the fibre bed.
For SPV mono-digestion in SD-AD and D-AD, the decline of methane yield (based on per unit VS) was most likely attributable to the rapid hydrolysis of carbohydrates in the initial phase of digestion and poor mass transfer capacity in high TS system, which weakened substrate conversion efficiency.
An experimental investigation of the maximum gas liquid mass transfer capacity OTRmax using the sodium sulphite system was extended to relative filling volumes of 4 16%, shaking diameters of 1.25, 2.5, 5, 7, 10 cm and shaking frequencies of 50 500 rpm for the above flask sizes.
The pressure gradient, total liquid hold-up and overall mass transfer capacity for non-foaming co-current upward flow of oxygen/water and oxygen/1 M NaOH through a bed of graphite felt were measured as part of a study of multiphase fluid dynamics in three-dimensional electrodes.
More modern (structured) packing materials have been developed that have a high mass transfer capacity at a lower pressure drop, which also comes along with a modified gas and liquid flow behavior.
