Catalytic dry gas analysis!
Thread Content
Dry gas analysis is performed every day; what components in the dry gas do experts mainly analyze? Which parts of the production process can these components then be used to produce! Please ask an expert for a detailed explanation! Thank you!
Changes in H2 content to analyze whether the catalyst is poisoned； The ratio of hydrogen to methane determines the amount of passivator to be added ； Analysis of CO and CO2 contents to determine the effectiveness of degassing by the regenerant ； The ratio of (C1+C2)/i-C4 is used to determine whether thermal cracking has occurred ； Determine whether there is excessive desorption based on C3 and C4 contents
The degree of the reaction can be analyzed from the test results.
Hydrogen-to-potassium ratio? and the ratio of hydrogen to methane
It can’t be the ratio of hydrogen to potassium, because there are no such components in the dry gas
For coaxial catalysis, we also need to consider the N2 component; if the amount of N2 suddenly increases, it is likely that there is a leak in the stripping section~~~
What’s going on? There were previous issues with excessive CO levels in propylene; it is suspected that this was brought in by the air currents resulting from the loosening of the regenerative inclined tubes
