Continuous reforming chlorine injection l
Thread Content
Chlorine is injected into the regenerator of the UOP continuous reforming process; the chlorine content in both the raw catalyst and the regenerated catalyst was analyzed. Why is the chlorine content in the raw catalyst higher than that in the regenerated catalyst? ? ?
1. Were two samples tested, and there’s no mistake? 2. Is the regeneration chlorine injection normal? 3. Is the regenerator operating normally? Chlorine is also lost during normal charring; otherwise, there would be no need for the original alkali washing of the regenerated gas or the current chlorine adsorption process.
Under normal conditions, the chlorine content is higher in the raw zone than in the regenerated zone. The poster can check the test results and ensure that the chlorine injection system is functioning properly.
1 Error in chemical analysis! Indeed, the chlorine content in 2 has decreased!
Go find someone who can do tests. Here, after using the dechlorination tanks several times, the chlorine level has been higher than before. We asked those who can conduct tests, and they said they couldn’t figure out the reason either: dizzy:
The test can be repeated; if there are no issues after the repetition, then experimental errors can be ruled out. It’s better to analyze each specific issue individually: First, determine the exact chlorine content values of the raw agent and the regenerated agent, and compare the data from the past month to see whether the level of chlorine in the raw agent is higher or that in the regenerated agent is lower; then proceed with analysis based on these two aspects. List the factors that affect the content of available chlorine, such as water content, chlorine content in the raw materials, and so on ； Breaking it down further, the factors affecting water content are analyzed in a list format. List the factors that affect the content of regenerated chlorine; by the same logic, verify each hypothesis against actual conditions one by one, and this will allow for quick analysis of the results.
Is there a chlorine adsorption process in regeneration? If so, it’s not surprising
Could the chlorine content in the feed be too high?
What chemical reactions occur in the chlorination-oxidation zone after chlorine addition? What is the substance that is removed through dechlorination?
If the analysis results are correct, then identify the process-related causes
