“…The K L values from the present study were comparable to those reported by Zander et al [8] who used a continuous flow (single pass) system and had air velocities on the shell side at least three times higher and an order of magnitude higher water velocities on the lumen side than this study. A higher overall mass transfer coefficient of oxygen was also obtained by Sengupta et al [30] for modules with liquid cross-flow on the shell side as compared with liquid flow on the lumen side.…”

The mass transfer of water and chloroform in membrane air-stripping (MAS) was studied using a microporous polypropylene hollow fiber membrane module, with air flow on the lumen side and liquid cross-flow on the shell side. Water transport experiments showed that its mass transport decreased significantly when the membrane had been in contact with water for prolonged periods. It was hypothesized that the increased mass transfer resistance was due to water condensation in a fraction of the membrane pores. MAS of chloroform from aqueous solutions confirmed the additional mass transfer resistance with prior exposure to water. It was concluded that membrane pores were either completely air-filled or partially wetted with water during the MAS process. Existing models are able to predict the performance only for either completely air-filled or liquid-filled pores. A modified model was proposed to take into account the diffusion through partially wetted pores. The model described the data well. This hypothesis also provided a plausible explanation to the conflicting literature values of the membrane mass transfer resistance. It was found that the membrane mass transfer resistance of the partially wetted pores is two orders of magnitude higher than that of air-filled pores. The overall mass transfer coefficient was constant for initial feed chloroform concentrations ranging from 50 to 1000 ppm. Crown

“…modules under similar operating conditions as in the present work. They were based on previous investigations [26,27] where the fiber bundle was assimilated to a densely packed bed and employed the hydraulic diameter of the bed of fibers in place of the outer diameter of a single fiber as is conventionally done. K EtOH m may be obtained by difference from Eq.…”

“…Nevertheless, RO leads to a wine concentration (water and ethanol transfer through the RO membrane) which requires diluting further with water issued from wine itself. Though SCC is performed at mild operation temperatures (26)(27)(28)(29)(30)(31)(32)(33)(34)(35) • C), this operation takes place in two steps: a first stage of aroma recovery and a second stage of ethanol removal. After ethanol separation, the aromatic fraction is added back to the wine, what results in a long and expensive operation.…”

“…PERMEA commercialises beer dispensing systems known as Cellarstream Dispense System using Pulsar gas/liquid contactors, which allow to increase or decrease the amount of CO 2 and N 2 in draft beer, thus achieving optimal characteristics. Other interesting applications include the removal of CO 2 from fermentation broths and the elimination of trace of oxygen from water for ultrapure water preparation, in the electronic industry [6].…”

Membrane operations, with their intrinsic characteristics of efficiency and operational simplicity, high selectivity and permeability for the transport of specific components, compatibility between different membrane operations in integrated systems, low energetic requirement, good stability under operating conditions, environment-compatibility, easy control and scale-up, and large operational flexibility, represent an interesting answer for the rationalisation of chemical productions. Many membrane operations are practically based on the same hardware (materials), only differing in their software (methods). The traditional membrane separation operations (reverse osmosis, micro-, ultra-and nanofiltration, electrodialysis, pervaporation etc.), already largely utilised in many different areas, are today completed with new membrane systems such as catalytic membrane reactors and membrane contactors. At present, the possibility to redesign important industrial production cycles by combining various membrane operations available in the separation and conversion units, so realising highly integrated membrane processes, is an attractive opportunity because of the synergic effects that can be reached. Additionally, the design of the integrated membrane production cycle in principle satisfy, the requirements for an advanced process intensification strategy.Membrane crystallizers, membrane emulsifiers, membrane strippers and scrubbers, membrane distillation, membrane extractors, etc., can be realized and integrated in the production line together with other existing membrane operations for advanced molecular separation and chemical transformations, overcoming existing limits of the more traditional membrane processes.
