The issue of additives for desulfurization of catalytic cracking gasoline
Thread Content
The processing capacity of the catalytic cracking gasoline desulfurization unit is 300,000 tons per year; so what are the amounts required of the hydrogen sulfide removal additive and the desulfurization additive? ?
Reply to 1# maijiajie: The consumption of hydrogen sulfide removal additives is not more than 0.06 Kg/T, while that of desulfurization alcohol additives is not more than 1.4*103 Kg/T
According to the regulations, we replace the hydrogen sulfide-removing additive once a month, or we analyze the alkali concentration when the hydrogen sulfide level is not within the acceptable range; if the concentration is below 10, we replace the additive. The amount of activator added is adjusted based on the thiol sulfur content determined through sampling and analysis of the gasoline
What color is your activator?
The alkali solution in the catalytic cracking gasoline desulfurization unit was replaced every half month; it is now replaced once a month.
May I ask the original poster: what is the sulfur content after desulfurization in your case, and does it meet the national standards?
