The issue of vinyl chloride conversion
Thread Content
There are problems with the synthesis and conversion of vinyl chloride: the conversion rate in Group 1 is low, and in Group 2 the excess acetylene level is 3%. What solutions exist? Thank you.
Check the reaction temperature and the ratio of components; mainly consider whether there are any issues with the catalyst, and analyze the mercury content.
By yesterday, the situation had worsened further; could there be problems with the adjustment of the converter? This post was last edited by limingshuguang on 2008-6-4 at 12:31
Currently, Group 1 has a lower temperature, while Group 2 has a higher temperature than Group 1
It might be that there is a problem with a certain group of catalysts, such as a low mercury content in mercury catalysts, or the catalysts being poisoned. It is recommended to analyze the mercury content in the catalyst.
I think it might be that the catalyst at the top of one of the converters has formed clumps; opening the upper cover of the converter and loosening it might help, as that could yield good results.
The converter is leaking; it can be seen that the leakage occurs at the upper part of the tubes, near the tube sheet, and it’s quite severe – the area affected by the leakage is large as well. The exhaust gas from the converter is normal, with no steam present. Please help analyze the cause. Thank you. This post was last edited by limingshuguang on 2008-6-4 12:32
Catalyst problem; go fix the catalyst!:lol
Dear all, please help by providing me with the syngas analysis results for each individual converter in Group 1 and Group 2. Thank you very much
One set of outlets: containing ≤30% acetylene; two sets of outlets: containing ≤2% acetylene
The catalyst conversion results in our facility are affected by slight changes in the flow rate of the feed gas, resulting in inconsistent conversion performance. Can it be considered a phenomenon that occurs in the later stage of catalysis?
