Dynamics of wet flue gas desulphurization in spray absorber
A concise one dimensional thermal-hydraulic two-fluid model is presented for the numerical prediction of sulphur dioxide absorption from the flue gas onto drops of the water-limestone slurry in the vertical spray tower absorber. The model is based on mass, momentum and energy balance equations for each phase separately, i.e. downward falling droplets of water-limestone slurry and upward flowing...
متن کاملInvestigation of Parameters Affecting Gypsum Dewatering Properties in a Wet Flue Gas Desulphurization Pilot Plant
Wet flue gas desulphurization (FGD) plants with forced oxidation, installed at coal and oil fired power plants for removal of SO2(g), must produce gypsum of high quality. However, quality issues such as an excessive moisture content, due to poor gypsum dewatering properties, may occur from time to time. In this work, the particle size distribution, morphology, and filtration rate of wet FGD gyp...
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 کاملRegeneration of СO2 Physical Solvents at Elevated Pressures in Gas-Liquid Membrane Contactor
In the present work, a membrane contactor with asymmetric flat-sheet poly(vinyltrimethylsilane) (PVTMS) membranes was proposed for the CO2 desorption process from physical solvents at elevated trans-membrane pressures. Different solvents were studied: water, a mixture of polyethylene g...
متن کاملSuperhydrophobic surfaces by electrospinning of polymer mixtures
Hydrophobic surfaces have found great interest in environment resist coating, antifouling marine structures and low friction devices whereas superhydrophobic materials, with contact angle higher than 150° [1], are of special interest in self-cleaning surfaces and stain resistant textiles. (Super)hydrophobicity is a key property that depends on both the surface chemistry and surface roughness. N...
