Hydrodynamics of a Gas-Solid Fluidized Bed at Elevated Temperatures Using the Radioactive Particle Tracking Technique
Effect of temperature on hydrodynamics of bubbling gas-solid fluidized beds was investigated. Experiments were carried out in the range of 25-600 ºC and different superficial gas velocities in the range of 0.17-0.78 m/s with sand particles. Time-position trajectory of particles was obtained by radioactive particle tracking technique. These data were used for determination of mean velocitie...
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 کاملThe Influence of Pressure on the Liquid Hold-up in a Cocurrent Gas-liquid Trickle-bed Reactor Operating at Low Gas Velocities
The influence of reactor pressure up to 6.0 MPa on the dynamic liquid hold-up in the trickle-flow regime with superficial gas velocities up to 5.2 cm/s has been investigated for water, ethanol and aqueous 40% ethyleneglycol, with nitrogen as the gas phase. Without gas flow, i.e. single-liquid trickle-flow operation, the reactor pressure has no influence on the dynamic liquid hold-up, which can ...
متن کاملParameters characterising the pulsing flow for cocurrent flow of gas and foaming liquid in a pressurised trickle-bed reactor
The aim of the present work was to experimentally determine the parameters characterizing the pulse flow of liquids through bed i.e. the frequency of pulsation and the velocity of pulses travelling along the bed and next to work out the correlation equations enabling their assessment. The research was carried out in a pressure reactor (pressures up to 2 MPa) having 0.05 m in diameter and being ...
