Benefits of catalytic oxygen-poor regeneration
Thread Content
Recently, I read some books on the oxygen-deprived regeneration of regenerators; it can help save energy and reduce consumption, as well as minimize catalyst wear. Our units have always used oxygen-enriched regeneration; we are not familiar with oxygen-depleted regeneration either. Do your units have the capability to switch from oxygen-enriched to oxygen-depleted regeneration? What are the advantages and disadvantages of oxygen-depleted regeneration compared to oxygen-enriched regeneration, and is it easy to operate? I hope to receive guidance from all the teachers. Thank you!
Oxygen-poor regeneration is not as easy to operate as oxygen-rich regeneration
This theory is primarily based on the concept of a low temperature and high oil-to-fuel ratio!
In previous years, it was said that saving steel involved making the regenerator smaller； The energy consumption is lower compared to oxygen-enriched regeneration.
Anoxic regeneration results in a relatively lower load on the main fan, saving electricity.
Advantages: 1. Anoxic regeneration, low main air flow, resulting in natural energy savings； II. The low temperature of the oxygen-poor regeneration bed reduces the hydrothermal deactivation of the catalyst, resulting in less catalyst loss. III. Tail burning does not occur. In addition, the disadvantages are also significant: the regeneration effect is poor, the carbon content in the regenerating agent is high, and the catalyst activity decreases. Only two regeneration units use this technology, one for oxygen-depleted regeneration. Such devices are almost nowhere to be found.
