Hydrodynamic Behaviour of a Gas-Solid Counter-current Packed Column at Trickle Flow
Trickle flow of a more or less fluidized catalyst through a packed column is a promising new gas-solid counter-current operation. The hydrodynamic behaviour of such a column, filled with dumped PALL rings, has been investigated, while some results have been obtained with RASCHIG rings and cylindrical screens as packing. The solid used was a microspherical catalyst carrier. Pressure drop, hold-u...
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 کاملHydrodynamic Simulation of Co-Current and Counter Current of Column Distillation Using Euler Lagrange Approach
Abstract—Packed columns of liquefied petroleum gas (LPG) consists of separating the liquid mixture of propane and butane to pure gas components by the distillation phenomenon. The flow of the gas and liquid inside the columns is operated by two ways: The co-current and the counter current operation. Heat, mass and species transfer between phases represent the most important factors that influen...
متن کاملHydrodynamic flow at RHIC
We review the apparently hydrodynamic behaviour of low transverse momentum particles (pT ≤ 1.5 GeV/c) produced in central and semicentral (b ≤ 7 fm) heavy ion collisions at RHIC. We investigate the impact parameter dependence of various observables, elaborating on radial and elliptic flow and particle multiplicities. We also discuss possible ambiguities in the initialization of the hydrodynamic...
