Solvent deasphalting, problems with deoiled asphalt.
Thread Content
What other products can be produced from deoiled asphalt next? Do any experts have any suggestions?
That solvent-deoiled asphalt? Solvent deasphalting can be used to produce blended asphalt, or the resulting product can serve as a raw material for coking (although the yield is not very good); in the case of particularly hard deasphalted oils, they are sometimes used as raw materials for gas production! It is connected to fertilizer plants and power plants behind! But from what I know, production equipment seems to be mostly used for mixing asphalt!
One factory I’m aware of produces fuel oil after reducing its viscosity.
Using it directly as fuel oil seems unreasonable in terms of price; how about using it for producing oxidized asphalt or asphalt with special grades?
It can be used as a raw material for producing finished road asphalt, for the purpose of blending asphalt. With the rapid development of highways, the prospects for finished road asphalt are quite promising, especially for high-quality asphalt with a grade of B or higher.
Options for rigid asphalt: 1. Blended road asphalt； 2. Use as coking feedstock ； 3. Produce fuel for thermal power plants ； 4. Use as raw material for gasification ； 5. Used as raw material for fertilizers ； 6. Feed into the viscosity-reducing cracking unit to produce fuel oil ； 7. Use as an asphalt additive after direct curing ； 8. Special asphalt.
I would like to ask, when comparing 1 and 4, which one offers better economic benefits and prospects for development?
Using road asphalt yields good benefits. But it is necessary to find a suitable harmonizing soft component
What are the ranges for the three indicators of the asphalt you produce, and what is the residue content of the deasphalted oil?
No production yet; I just wanted to ask what products will be available in the future that would utilize this device
The market for asphalt is already saturated in China; I have data to prove this. I’m not sure what the overall process is in your refineries; as the final stage in heavy oil processing, this process represents the most cost-effective option
