Advantages and disadvantages of reprocessing slurry oil
Thread Content
Is it more beneficial to reprocess the slurry or to dispose of it externally? Disposing of it externally yields a benefit of around 5%. The gasoline production option involves adding slag
Slurry is an important factor affecting catalytic efficiency; a decrease in slurry yield will inevitably lead to an increase in the yield of light liquids. Moreover, a lower amount of slurry being discharged reduces the wear and tear on pipelines and equipment. The poor properties of the slurry increase the regeneration temperature, thereby affecting the total feed to the catalyst; to ensure an adequate total feed, it may be necessary to take into account the balance with residue oil
I think it’s better not to recycle it, as the oil slurry contains high levels of heavy metals, which can easily poison the catalyst and cause it to become inactive. Moreover, the oil slurry itself is mostly made up of large molecular substances, making it difficult to atomize and thus unsuitable for reactions
