Study of the hydrodynamics in a pervaporation module and implications for the design of multi-tubular systems

A non-equilibrium thermodynamics approach to model mass and heat transport for water pervaporation through a zeolite membrane

“…Under isothermal conditions, Eq. (8) reduces to (12) This equation is often referred to as the M-S equation [2]. When Eq.…”

“…By neglecting the coupling effects and the contribution of the interfaces, the model was simplified to Eqs. (12) and (23), which is referred to as the nCnS model.…”

Pervaporation performance of PPO membranes in dehydration of highly hazardous mmh and udmh liquid propellants

“…Membranes based on cellulose derivatives and polyvinyl alcohol were found to degrade in more concentrated solutions viz. >50 wt% MMH / UDMH (pH [13][14]. Therefore, an alternate membrane material capable of showing better chemical resistance was required for dehydration of MMH and UDMH.…”

“…Liu et al [13] have presented a hydrodynamic analysis to find out the effect of baffles on mass transfer in a slit-type PV module. Fontalvo et al [14] have studied the hydrodynamics in a PV module and reported implications for the design of multitubular systems. Rezakazemi et al [15] developed a mathematical model to study the PV dehydration of water-ethylene glycol mixtures.…”
