Oxidative scrubbing is used to remove H2S from gas streams. A key problem in regeneration of the absorbent is the removal of fine particles of sulphur from the suspension of the scrubbing liquid. Dispersions of ultra-fine bubbles have been called "colloidal gas aphrons" or aphrons for short. These dispersions have interesting properties and it was found that they have particular advantages in t...
Background and Objectives: Cyclone is one of the most utilized dust collectors for airborne particles control. It separates particles from airflow by centrifugal force. However, it is not effective in collecting very fine particles smaller than 10 μm in diameter. The aim of this study was to assess the performance of charging particles on cyclone efficiency in collecting particles smaller than ...
This discussion paper is/has been under review for the journal Atmospheric Chemistry and Physics (ACP). Please refer to the corresponding final paper in ACP if available. Abstract A detailed characterization of air quality in Paris (France), a megacity of more than 10 million inhabitants, during two one month intensive campaigns and from additional one year observations, revealed that about 70 ...
It is vell known that fines and ultrafines can cause severe problems in mining and mineral processina. The decrease in the grade of ore combined with the arowinS demand for aineral products baa led to the minina and milling of increasing tOQnage or ore. Cl08ely linked with the problem of reduction in the grade of ore is. the more serious problem of the decrease in libration size. A direct cODsq...
