Heat Transfer in a Column Packed With Spheres
The purpose of the study is to investigate average and local surface heat transfer coefficients in a cylinder packed with spheres. Here the term «local» applies to a single sphere within the bed. Averages are derived from the sixteen different spheres that were instrumented and distributed throughout the bed. The experimental technique consisted of introducing a step - wise change in the temper...

Nicole Riddell (2017): Packed Column Supercritical Fluid Chromatography: Applications in Environmental Chemistry. Örebro Studies in Chemistry 19. Although gas and liquid chromatography have emerged as dominant separation techniques in environmental analytical chemistry, these methods do not allow for the concurrent analysis of chemically diverse groups of persistent organic pollutants (POPs).

متن کاملAbsorption of Carbon dioxide in Packed Column
The absorption of carbon dioxide into aqueous ammonia solution using packed column was investigated. The volumetric overall mass transfer coefficients (KGav) for CO2 absorption into aqueous ammonia solutions were evaluated over ranges of main operating variables , that is, upto 16kPa partial pressure of CO2, 61-214 m 3 /(m 2 .h) gas flow rate, 0.753.06 m 3 /(m 2 .h) liquid flow rate, 2%16% ammo...
متن کاملGas-solid Trickle Flow Hydrodynamics in a Packed Column
The pressure gradient and the static and the dynamic hold-up have been measured for a system consisting ofa Fluid Cracking Catalyst (FCC) of 30-150 x 10m6 m diameter, trickling over a packed bed and with a gas streaming in countercurrent flow. The experiments were carried out at ambient conditions using a glass column of 25 x 10 ~’ m diameter. The packing material consisted of 8 x 8 x 3 mm cera...
متن کاملCFD Simulation of a Wetted-Wall Column for Natural Gas Sweetening Using DEA Solution
Natural gas usually contains significant amounts of acid gases when it is extracted from underground reservoirs. Therefore, it must be treated by appropriate processes to remove these acidic components. In this study, the simultaneous absorption of carbon dioxide and hydrogen sulfide from natural gas into diethanol amine solution was simulated using CFD. Absorption process was performed in a we...
