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.
Adopting of drink water conditions needs sterilization from the resource. There are many used matter to sterilize, but the most use is by Chloride, so it is necessary to obtain solutions because of continuous damages due to sterilization operation.
The water sterilization by chloride may create secondary compounds in water, which are very dangerous. Those compounds are as Trihalomethanes (THMs) which cause crabs. Therefore, we researched the sterilization by chloride in comparison with other ways. In addition, we get rid off hydro carbonates from sterilized drink water samples, which were obtained from different resources, drink water, natural water and dames using the activated carbon to get rid off venole and humic acids not to interact with chloride and cause people cansers.
Fluoride ion is present in high concentration in some regions in Syria. As
fluoride occurs naturally in water, We have studied some methods of fluoride
removal such as Nalgonda technique and activated carbon method.
In Nalgonda technique we add Al
um and lime to the water, and we have
found that fluoride removal efficiency remains constant when the initial
concentrations of fluoride changes, or when the chloride ions exists in water,
but it depends on pH, and get better when the method is investigated in two
steps. In addition, adsorption of fluoride decreases with increasing
sedimentation time, or using Ventilated lime or CaCO3 instead of Ca (OH)2.
In activated carbon method we have done different experiments by using
charcoal of coconut coir, date seeds and olive seeds. And we have found that
olive seeds carbon is better than others, and its fluoride removal efficiency
increases after impregnation with solution of 2% Al2(SO4)3.
In this work, the study of
the process had done in reducing the percentage of sulfur and
aromatics in by effective adsorption using active carbon. Where the
study showed the effect of weight change in the proportion of coal
to fuel oil processor weight, the percentage of sulfur and aromatics
removal in terms of changing the stirring time (mix).
