These porous membranes show water fluxes of about 30,000 L/m2 h bar and oil fluxes of 900 2000 L/m2 h bar at 60 °C.
Arrival times of oil fluxes and water fluxes need to be distinguished (as visualized in our study) to enable allocation of water-cut ratio to the producer based on WAFs.
One would need to distinguish between arrival times of oil fluxes and water fluxes to enable allocation of water-cut ratio to the producer based on WAFs (e.g., Nilsen and Lie 2009).
In these test conditions, the other influence factors including the refrigerant type, oil concentration, heat flux and initial liquid-level height are fixed.
In these test conditions, the other influence factors including the CNTs physical dimension, oil concentration, heat flux and initial liquid-level height are fixed.
Several parameters affecting the heat transfer coefficient and pressure drop of refrigerant oil mixture, such as oil concentration, mass flux and vapor quality were investigated.
The CNTs physical dimension, refrigerant type, oil concentration, heat flux, and initial liquid-level height are five important factors influencing the migration of CNTs, and should be reflected in the new model.
The effects of pressure (13 27 bar) and temperature (21 49 °C) on permeate flux, oil retention and separation of free fatty acids (FFA) were evaluated by a 22 complete factorial design, with three central points and four axial points.
It can be seen from Figure 8a to e that the migration ratio of CNTs predicted by the model and the experimental data have the same tendency changing with the CNTs physical dimension, refrigerant type, oil concentration, heat flux, or initial liquid-level height.
