A score of 3 was given for severe metal transfer, that is, when a longitudinal, concentrated metal transfer stripe was observed or when metal transfer of any type was observed over the majority of the upper hemisphere [ 1].
Therefore, there is a severe mass transfer limit for the transport of these species through the vapor phase.
This model-based design methodology is generally applicable to different multiphase reaction systems with severe mass transfer limitation.
It was found that the model predicts the formation of hollow particles in the presence of severe mass transfer limitations, in accordance to what is found experimentally.
The extended methodology is applied in the reactor design for chemical absorption of CO2 as an example for complex multiphase reaction systems with severe mass transfer limitation.
Complex micro scale geometry, low Reynolds number operating condition and high surface to volume ratio all lead to severe heat transfer.
Results show that there may be severe mass transfer limitations depending either on the design or on the water management of the cell.
The fixed-bed reactor that was assumed to operate in the trickle-flow regime has a particularly low catalyst specific productivity due to severe mass transfer resistances.
However, there are some disadvantages with their use, such as gel degradation, severe mass transfer limitations, low mechanical strength as it can cause the release of cells from the support and large pore size.
One patient developed severe postoperative transfer metatarsalgia, treated successfully with a second-time percutaneous osteotomy of the minor metatarsals, whilst one patient had wound infection that resolved with systemic antibiotics.
