Fabrication and Characterization of Polyetherimide Hollow Fiber Membrane Contactor for Carbon Dioxide Stripping from Monoethanolamine Solution
In this research, process asymmetric polyetherimide hollow fiber membranes using ethanol (0, 2 and 4 wt%) as non-solvent additive in the polymer dope via phase inversion method were fabricated. Aqueous solution of 1-methyl-2-pyrrolidine (NMP) (90%) was applied as a bore fluid to avoid inner skin layer formation and water was used as the external coagulant. The morphology of fabricated membranes...
متن کاملCounteracting ammonia inhibition in anaerobic digestion by removal with a hollow fiber membrane contactor.
The aim of the current study was to investigate the feasibility of membrane contactors for continuous ammonia (NH₃-N) removal in an anaerobic digestion process and to counteract ammonia inhibition. Two laboratory anaerobic digesters were fed slaughterhouse wastes with ammonium (NH₄⁺) concentrations ranging from 6 to 7.4 g/L. One reactor was used as reference reactor without any ammonia removal....
متن کاملEffect of Ethylene Glycol as Pore Former on Polyphenylsulfone Hollow Fiber Membrane for Crude Palm Oil Deacidification through Membrane Contactor
In this study, polyphenylsulfone (PPSU) hollow fiber membrane was fabricated via a wet spinning method with the addition of ethylene glycol (EG) in the range of 0-10 wt% as the additive. The EG was added to improve the membrane pore formation and interconnectivity for better membrane contactor performance in extracting and removing the free fatty acid (FFA) from crude palm oil (CPO). Four diffe...
متن کاملPolyvinylidene Fluoride Hollow Fiber Membrane Contactor Incorporating Surface Modifying Macromolecule for Carbon Dioxide Stripping from Water
Porous surface modified polyvinylidene ïuoride (PVDF) hollow fiber membranes are fabricated through a dry-wet phased inversion process. Surface modifying macromolecules (SMM) (1 wt. %) are used as additives in the spinning dope. The performance of the surface modified membrane in contactor application for CO2 stripping from water is assessed through the fabricated gas–liquid membrane contacto...
متن کاملAmmonia Removal From Water By a Liquid-Liquid Membrane Contactor Under a Closed Loop Regime
Introduction: Removal of ammonia from water of a waste water treatment plant by a membrane contactor were simulated on transient state and compared with experimental data. This technology will be applied in the hydrogen and oxygen production by electrolysis via renewable energies as can be seen in Figure 1. The aim of this study relies on fulfill the process requirements in the electrolysis, si...
