In this resecarh the improvement of SO3 absorption via oxidation of
SO2 ,which is a by product from a chemical plant in Damascus ,
using Ozone and active carbon – was stadied .
The main purpose of this research paperis :
. To obtian acceptable co
ncentrations of sulphuric acid in various
aqueous mediums .
. To eelease SO2gas as a by product frome this flow .
The lab study assures that the absorption of sulphuroxides differ
from medium to other with or not existance of active carbon in
aqueous medium and bubbling the gas oxides and distillated water
only and also the bubbling of Ozone gas in gasoxides.
The dissolution rate of Iron and Titanium from Syrian basalt rock was
studied by hydrochloric acid, sulfuric acid, mixture of hydrochloric acid
methanol, sulfuric acid methanol solutions. The effects of temperature, time of
digesting and concentra
tions of acids have been investigated, the ratios of solid
to liquid and stirring speed were constant (S/L=0.02). It has been clear that
when the mixture of hydrochloric acid and methanol (100:50(V:V)
HCL:CH3OH) was used, the best dissolution for both iron and titanium was
obtained when we digested the rock and it took 6h at 100 ˚C where as the
concentration of hydrochloric acid and methanol were [HCl]=11M, [CH3OH]
=0.92M, the resulting ratios of dissolution of iron and titanium in the
mentioned conditions were 75.53%, 63.19 % respectively.
