What are the reasons for a high distillate content in the product?
It’s sulfur, right? That’s included in your raw materials; there should be desulfurization facilities somewhere earlier on
Um, I’m sorry for the typing mistake; the sulfur content has been on the high side
Welcome to the technical exchange group for alkylation and spent acid units – let’s discuss and share knowledge together: 546996393
Edit and modify it yourself then:lol
Which is your alkylization design institute? If it’s the concentrated sulfuric acid catalyst method used by Lanzhou Global, then the sulfur content in the raw materials is one factor to consider; generally, this factor has a minor impact, as the carbon tetra compounds obtained after etherification already have a low sulfur content； It is mainly related to the operational control of the reaction process, or issues with the equipment itself; if methanol is not handled properly during raw material processing, it may also lead to a high sulfur content
There’s no issue with the raw materials, nor is there a problem with the sulfuric acid concentration; both the alkene-to-olefin ratio and the reaction temperature are normal. The problem now is that the dry point is excessively high
This phenomenon also occurs after long-term, large-scale production; the sulfatides formed adhere to the inner walls of the equipment, contaminating the oil and making it difficult to remove
This phenomenon also occurs after long-term, large-scale production; the sulfatides formed adhere to the inner walls of the equipment and contaminate the oil, making it difficult to remove – the same is true for us as well.
