Future prospects of solvent deasphalting
Thread Content
Let’s discuss the prospects of the solvent deasphalting process in the context of the trend toward lighter heavy oils
The prospects seem good; currently, various companies are adopting this system, and it represents an effective process for processing heavy oil
Leaching currently yields good results and performs well. The leaching process is quite satisfactory
The prospects are good; once the asphaltenes are removed, coking is no longer necessary
It seems that there are few elution units these days; new refineries basically don’t have such devices
This is a device necessary for producing polishing oils and microcrystalline waxes
This technology has little future ahead of it; it was developed for a period in the last century, but development has essentially come to a halt nowadays, with very few new companies pursuing this project! After actually trying it out, it turns out that it is somewhat useful for lubricating oils, but it doesn’t hold much value for producing asphalt or light-grade materials!
It depends on what your product goals are Simple separation doesn’t yield much benefit!
Solvent deasphalting can replace coking, and it makes sense to produce lubricating oils afterward.
It cannot completely replace coking; the separated heavy oil still needs to go through coking in order to produce gasoline and diesel!
I heard that Fujian has installed a new solvent deasphalting unit as part of its refining and chemical integration project, but it is not intended for producing asphalt products. Instead, the deoiled asphalt is used as fuel in boilers and for gas production (hydrogen generation), which helps to reduce the costs associated with hydrogen production. Moreover, boilers using this material do not require coal storage areas or slag disposal sites, making their operation more convenient. Is there anyone who is aware of the situation and can share some insights? Those who have relevant information, please share it
