An experimental study has been carried out of the two phase counter-current gas-liquid flow in a packed bed column operated in the proximity of the flooding point under periodic variations of inlet velocity of gas or liquid. Additional experiments have been focused on evaluating axial dispersion characteristics in the proximity of the flooding line in both liquid and gas phase using inert trace...

The present work discusses IR spectroscopic experiments and quantum- chemical DFT study of structure intermolecular binding in the intermediate gas?liquid systems aromatics, namely, benzene, furane, pyridine thiophene. These can be generated thin layers near a solid surface by two different methods, depending on physical properties sample. first method includes evaporation with subsequent compr...

When oil fields fall during their lifetime below the bubble point gas comes out of solution. The key questions are at which saturation becomes mobile (“critical saturation”) and what mobility is, because reduces production significantly. traditional view is that phase once bubbles grow or expand to a size where they connect form percolating path. For typical 3D porous media corresponding this p...

The main objective of this paper is to examine the effect of nanomaterials on mass transfer coefficient in bubble type absorption of carbon dioxide by experiment. The absorption process is carried out in a bubble column and in room temperature. Mass transfer coefficient, saturated concentration of CO2, and gas holdup are determined in this system. The kinds of nanomaterials, the concentrations ...
