We are seeking cooperation on the project titled “New desulfurization process to reduce the generation of alkali slag”.
Thread Content
The current processes in the petrochemical industry that generate alkaline sludge include catalytic gasoline refining, coking and liquefied gas refining, alkane dehydrogenation with sulfur injection, as well as tetrachloroethylene and chlorine production units. The existing facilities for handling this alkaline sludge are not capable of meeting the requirements; disposing of it as hazardous waste involves high risks and significant limitations in terms of processing capacity. It is therefore necessary to find new processes that can replace fresh alkaline solutions in desulfurization and dechlorination units, thereby reducing the amount of alkaline sludge generated and ensuring its safe disposal. Those who are interested can contact me. 15351997677 (same number on WeChat)
Waste alkali slag can be fed into an acidic water stripping tower for treatment, but the processing capacity is limited!
LPG desulfurization does not produce alkaline slag, so no treatment is required!
The coking and gas fraction liquefied gas refining section must be the double dehydration process; this process now exists without the generation of alkali slag.
Hello, I’m not from a design firm; I’m just an operator. I don’t know exactly what the sulfur content in what you produce and use is. I recommend a method that I hope will be helpful to you.
Cobalt-molybdenum hydrogenation converts organic sulfur into inorganic sulfur; zinc oxide is used for small amounts, while methyl diethanolamine is used for larger amounts
