Flow through Packed Beds and Fluidized Beds

Chemical engineering operations commonly involve the use of packed and fluidized beds. These are devices in which a large surface area for contact between a liquid and a gas (absorption, distillation) or a solid and a gas or liquid (adsorption, catalysis) is obtained for achieving rapid mass and heat transfer, and particularly in the case of fluidized beds, catalytic chemical reactions.

Morphometric Properties of Glacial Cirques in Zagros Mountain, IRAN

The morphometry of 187 cirques like forms is performed in the selected regions of Zagros Mountain with the use of GIS. The cirques like forms were delimitated manually and their headwall and floor boundaries were modified based on the classified slope map. The power law functions were fitted to 187 longitudinal cross-sections of the cirque like forms and their parameters were analyzed. All the ...

Equity in distribution of hospital beds in Iran

Background and Aim: Equitable distribution of health system resources and hospital beds is crucial for an acceptable level of health for all the people of the country. The aim of this study was to examine the equity in distribution of hospital beds in Iran. Materials and Methods: In this descriptive and cross sectional study data were collected from Ministry of Health and Medical Education and ...

Dispersion Coefficients of Supercritical Fluid in Fixed Beds

The axial dispersion coefficient of hexachlorobenzene in supercritical carbon dioxide is investigated in a fixed-bed packed with glass beads. The on-line chromatographic pulse-response experiment is used in order to study the dynamics of a packed column under supercritical conditions. The radial dispersion is assumed negligible because of the packed column geometry. To estimate the axial disper...
