In this work, selective absorption of H2S from a gas mixture with CO2 into N-methyldiethanolamine (MDEA) is investigated experimentally and theoretically in rotating packed bed (RPB). the RPB, various speeds, flow rates, liquid concentrations MDEA aqueous solutions were studied by means evaluation removal efficiency, selectivity, overall volumetric mass transfer coefficient. The reaction−diffusion model based on penetration theory for process developed, accordingly. results experiment show...
For the simultaneous absorption of H2S and CO2 into methyldiethanolamine (MDEA) solution, MDEA in fact is selective toward both CO2. It kinetically thermodynamically Selective removal using a rotating packed bed (RPB) solves problem that large amount accompanying simultaneously removed conventional desulfurization process. An RPB highlights restricts its selectivity In this work, an industrial test for was performed. Compared with tower has substantial advantage H2S. A...
This study introduces an approach to isolate the packing area from whole rotating packed bed (RPB) by N2 flow and measures effective mass transfer in shell zone. On basis of chemical absorption CO2 NaOH aqueous solution, experiments are carried out detect effects speed, temperature, liquid rate, gas rate on area. Experimental results show that RPB is independent temperature direct proportion speed. In same experimental conditions, zone takes up around 30% area, while other 70%. our settings,...
The work presents a theoretical investigation of the absorption CO2 by aqueous solutions N-methyldiethanolamine (MDEA) in rotating packed bed (RPB). diffusion-reaction process for CO2-MDEA mass transfer RPB is modeled according to Higbie's penetration theory with assumption that all reactions are reversible. A three-dimensional distribution carbon dioxide concentration varying time and depth liquid film an average rate at interface obtained. intensification within mainly achieved sharper...
The pressure drop across packed beds that are rotating differs in significant and unexpected ways, compared to the behavior conventional beds. For a wide range of operating conditions, (1) an irrigated bed can be significantly lower than dry (2) for fixed outer diameter, increasing depth (i.e., more transfer units) result reduction bed. Furthermore, power required spin rotor diminishes as vapor flow rate increases. Previously published correlations on do not explain or predict these...
Abstract Surface modification is an important technique for maintaining relatively favorable mechanical properties to surface and corrosion resistance. In this study, shot peening technology applied low alloy steel production nanocrystallines. The microstructure near the layer was characterized by x-ray diffraction, transmission electron microscopy backscatter diffraction. behavior of shot-treated analyzed polarization pitting test, morphology corroded sample observed a scanning microscope....
In this study, X80 pipeline steel is prepared with different Nb contents through the thermo-mechanically controlled rolling process. The effects of using two on impact toughness and microstructure are examined various experimental techniques. results show that increase in content, transformation temperature Ar3 decreases, nucleation growth bainitic ferrite lath features (LB) promoted, while those granular bainite (GB) inhibited. addition, stability austenite phase increases content....
Abstract The effects of cold deformation on tensile properties and corrosion behavior the Ti-6Al-3Nb-2Zr-1Mo alloy are investigated in present work. microstructure sample was characterized by means x-ray diffractometry, scanning electron microscope backscattered diffraction. HCl solution potentiodynamic polarization test. results show that α laths became kinked after rolling interlamellar spacing decreased to about 0.45 μ m at reduction 50%. kinking process closely linked with development...
Abstract In this paper, the effect of sulfur dioxide (SO 2 ) on corrosion behavior weathering steel with different copper (Cu) contents in a simulated industrial environment was studied. The results showed that occurred three distinct stages kinetics characterized via parameter ‘n’. For first and second stage n > 1 < 1, accelerated reduced, respectively. third witnessed minimum value n, indicating lowest rate. As Cu content increased from 0.15% to 0.50%, weight gained rate remarkably...
