Regenerator spray combustion oil

Just include the value shown by the flow meter directly in the energy consumption calculation

Is combustion oil sprayed during normal production as well? Is it the combustion oil sprayed during operation that is also counted as energy consumption? They go to such detail in their work!

Under normal production conditions, no combustion oil is injected; it is only added during startup and in emergency situations, as well as when the heat balance caused by the very light components of the raw materials is insufficient to maintain production. Burned oil is generally counted as startup loss or accident loss. Energy consumption is not included.

This can’t be considered normal wear and tear; generally, there’s no need to spray except during maintenance.

Due to the characteristics of our company, external steam supply is required for our workshop; therefore, burning oil is generally used for combustion

Does long-term use of burning oil have an impact on the catalyst’s activity? I can’t remember exactly; I think it was around 1990. In our catalytic units, the reaction temperature for the hydrogen feedstock was 450°C, while the bed temperature was a little over 620°C. Sometimes, it was necessary to inject combustion oil in order to raise the bed temperature to above 640°C. We used Y15 catalysts, and it seems that injecting combustion oil had a significant impact on the catalyst’s activity. In our current production operations, the catalyst is used in a manner similar to a boiler; the amount of slag added is used to adjust steam generation in order to maintain the overall steam balance of the plant. The technicians working on the catalyst system reduce the stripping effect in order to ensure maximum steam output. It’s not worth it. I recommend purchasing a 30-ton fuel boiler for daily heat supply, to adjust the steam demand across the entire plant and in emergency situations, thereby freeing up operators to focus on catalyst adjustments.
