Osmotic evaporation (OE) process is usually suggested to concentrate aqueous solutions. OE is a concentration technique based on the use of mesoporous or macroporous and hydrophobic membranes. The difference between the activity of solutions results in a pressure difference between the upstream diluted solution and the downstream (usually concentrated brine) solution. The latter generates a wat...

this research includes both experimental and cfd investigation in the hydrodynamic behavior of a new type of column tray introduced as “concap” tray. the proposed column tray is used in contactor columns especially in stripping columns. the hydrodynamics of this concap tray is investigated in a 1.2m in diameter column. using air-water system, the experiments were performed for different liquid ...

• Novel Ionic Liquid that is not corrosive to aluminum used as liquid desiccant. New three-fluid fin-tube desiccant contactor fabricated using aluminum. Experimental performance of the IL solution investigated. The fin–tube showed superior than packed bed contactor. Lower flow rates and pumping power expected experimental a new novel ionic investigated compared with those an adiabatic LiCl for ...

In this work, a comprehensive mathematical model was developed in order to evaluate the CO2 capture process microporous polypropylene hollow-fiber membrane countercurrent contactor, using monoethanolamine (MEA) as chemical solvent. terms of absorption, showed excellent agreement with experimental data published literature for wide range operating conditions (R2 > 0.96), 1–2.7 L/min gas flow ...

the carrier facilitated transport of lithium picrate was studied using a series of non-cyclic polyethers containing different end groups and chain lengths through bulk liquid membrane (blm) and supported liquid membrane (slm) systems. the various membrane supports used are viz. ptfe, cellulose nitrate, and dialysis membrane and onion membrane. the amount of li+ transported depends upon the stru...
