Are petroleum coke and asphalt the same thing?
Thread Content
I’ve just started learning about oil refining; I searched online, but the information available was not clear at all. Could you please explain it in detail? Thank you!
What are the production processes for petroleum coke and asphalt, respectively?
Petroleum coke is a type of coke; it is produced when asphalt undergoes delayed coking.
That makes it clear then – what kind of product is asphalt?
Petroleum coke is generally a solid substance formed in delayed coking units； Asphalt is a type of petroleum asphalt produced in a vacuum distillation tower (containing some light components and remaining liquid at high temperatures)
Petcoke is a product of delayed coking, while asphalt consists of some high-molecular-weight components in petroleum
Asphalt is available that is drawn directly from the bottom of the vacuum distillation tower, and it is blended with catalytic slurry to produce road asphalt； Another method involves using vacuum residue, which is then processed through a solvent deasphalting unit to remove the deasphalted oil – that is, the catalyst feedstock ； The third type is those with natural asphalt deposits, which are extracted directly
