The sulfur content in the alkylated products cannot be reduced
Thread Content
The alkylation unit has been in operation for a week now, and the requirement is that the S content be below 10 ppm; no matter how much we try to adjust it, we can’t get it below that level. Seeking help from experts. Thank you
It is correct that the sulfur content in general alkylated oils is less than 5PPM. It is recommended that you start by checking the following: 1. Verify whether the laboratory test results are accurate by having the samples tested elsewhere for comparison. 2. I wonder what process you use, Rums? DuPont? Know good techniques to offer advice. Acid hydrocarbon separation method.
What are the specific operational parameters? You can also upload images to resolve the issue.
Your raw material is excellent; the oil yield must be very high, right?
Acid hydrocarbon ratio, alkene to alkane ratio indicators, content of raw material S; the description of the problem is vague, making it impossible to provide an explanation
Whether the raw material contains hydrogen sulfide. What is the total sulfur content? Is 7.23 the pH of the alkali cleaning solution? Try raising it to 8. Is there also an analysis for the isobutane removal step?
Take a look, alkali washing flow rate, alkali washing temperature
