Problems with alkylated products
Thread Content
In the alkylation reaction with sulfuric acid, what causes the product octane to turn yellow? Is it due to alkaline washing or water washing?
I heard about discoloration for the first time; did it occur at the beginning of operations, when the plant first started up? This situation shouldn’t last for long. Are there any water-soluble acids or bases in the test results? Did the doctor pass? What are the main components of isooctane? What is the temperature for the alkali cleaning cycle? Is the bottom temperature of the isobutane removal tower normal? Has there been any issue with being unable to handle low temperatures?
The impact caused by alkaline cleaning might be significant; it should improve after running for some time
