Where are the oxygen analyzers for coking during the regeneration of continuous reforming catalysts located? How to supplement oxygen in the first and second stages on a regular basis
Thread Content
Is the oxygen analyzer located at the inlet of stage 1 and 2 coking, or at the inlet and outlet of stage 2 coking?
It is installed at the inlets of Section 1 and Section 2 in the charring zone; no make-up air is required under normal conditions for these sections. Make-up air is used in Section 2 during startup, while under normal operations, make-up air is supplied through the oxychlorination roasting zone
Thank you. When should supplemental oxygen be used in that scenario, and how can operations be adjusted based on the data from the oxygen analyzer?
Air is added based on the degree of charring; this method is not commonly used, with the oxygen content kept at 8%
If the amount of char formed is high, should the oxygen content be increased or the flow rate of the regenerated gas?
Increase the oxygen content! But it is generally kept at around 8%
