Methods for treating residue oil
Thread Content
The treatment methods for vacuum residue are hydrogenation or decarburization. With the same feedstock and the same feed rate, which is more efficient: residue hydrocracking or delayed coking or flexible coking? ?
From the new information I’ve seen, Sanju Environmental Protection’s fluidized bed cracking technology is quite good, allowing for high yields with minimal input.
So, does that mean that under the current market conditions, hydrogen production is more economical than carbon removal? ?
The level of returns depends not only on the product but also on the investment; the investment required for hydrocracking is relatively higher!
The investment in hydrocracking is high, but in the long run, isn’t hydrocracking supposed to have more advantages than decarbonization? ?
In the long run, hydrogenation has more advantages, but it’s not absolute； If decarburization can produce high-quality coke, it still has its advantages; it’s better to decide based on one’s own needs
It mainly depends on crude oil prices. When crude oil prices are high, hydroprocessing of residue is more profitable; when crude oil prices are low, delayed coking is more advantageous
Now, there are very few new projects in the field of delayed coking; most of them involve additional hydrogenation
What is the prerequisite for producing high-quality coke through decarburization? ? Is it better to have better raw materials or more advanced manufacturing processes? ?
Based on the current situation, it seems that hydrogenation offers better benefits.
