Some problems in acid-base refining of crude gasoline
Thread Content
I want to make a gasoline acid-base refining device with a processing capacity of about 30 cubic meters per hour. 1. Is there any ready-made process plan or drawings in the forum:time:. 2. What materials are needed for acid and alkali cleaning tanks, and what is the wall thickness? 3. What is the appropriate ratio of acid-base to oil, and what is the required concentration of alkali solution: $. 4. During alkali cleaning, the alkali solution can be circulated in a small way, which will improve the effect and cost? God, save me! ! !

Just stick to the old rules. :lol
Can you tell me the properties of gasoline? Why do we need acid-base refining?
1. Although the National III standards will be implemented this year, the acid-base washing process for light oil products still has value. 2. Acid-alkali washing process. Nowadays, only alkali washing is generally used instead of pickling. . . Just afraid of acid corrosion. . . 3. Steel's ability to withstand alkali is much greater than its ability to withstand acid. . . 4. The commonly used concentration is generally light alkali. . . Around 10%. 5. Alkali solution can be recycled. . . The cost is about 10 yuan. 6. Organic acids and alkalis can be used to wash gasoline. . . Organic acids are weakly acidic. . . Not quite as corrosive. . . :lol
The raw materials have poor properties and contain a lot of S derivatives and magazines, and are dark in color and smelly. The result after sample processing is good. But if you don’t know what material to use when making equipment, and you feel that there is emulsification when making samples. How can the acid cleaning tank and the alkali cleaning tank be fully separated when production is scaled up?
After washing with alkali, using fixed bed sulfonated cobalt titanine oxidation method to remove thiol can solve the odor and color.
Now I use pre-alkaline washing + fixed bed deodorization. However, since the color of the raw materials is unstable and the colloid content is about 10, I am worried about the life of the activated carbon. So I plan to do an acid and alkali wash first. Is there any other good way to remove gum?
I recently developed a new refined preparation and started using it in Yanshan, Beijing. The treatment object is coked gasoline, which can reduce sulfur from 1100 to about 600PPM. The PhD experiment of colloid 3.5 passed. If you are interested, please email to discuss or leave your phone number at9000@126.com
