What are the advantages and disadvantages of hydrogenation of catalytic cracking feedstock versus hydrogenation of the products?
Thread Content
To ensure that gasoline and diesel meet the National 3 and National 4 standards, refining the feedstock for catalytic cracking or refining the finished products are two relatively practical approaches; let’s compare the advantages and disadvantages of each approach. Which one is more economical?
If it is only necessary to ensure that diesel and gasoline meet National Standard 3 and National Standard 4 requirements, product hydrogenation can be an option; this approach requires low operating pressure and is relatively cost-effective in terms of investment. If the overall benefits of the facility and its impact on subsequent units are taken into consideration, it is preferable to carry out feedstock hydrogenation; our company currently uses this process route.
Refining the feedstock for catalytic cracking or refining the product are two relatively practical approaches; let’s compare the advantages and disadvantages of each approach. Which one is more economical? Advantages of refining the feedstock for catalytic cracking: 1. High yield of light oils ； ⒉Increased catalytic processing capacity ； ⒊It offers high comprehensive benefits. Disadvantages: 1. High investment required for residue hydrogenation ； ⒉The process is complex. Advantages and disadvantages of refining products: Advantages: 1. Simple process ； ⒉Small investment amount ； ⒊Operational risk is low. Disadvantages: 1. Low processing capacity for raw materials ； ⒉The light oil yield is low. Overall, it makes the refining of catalytic cracking feedstocks economical.
