Process differences between heavy traffic asphalt units and atmospheric and vacuum distillation units and related information
Heavy traffic asphalt is generally formulated from oxidized asphalt, asphalt produced by propane deasphalting units, vacuum residue (for some heavier crude oils, atmospheric heavy oil is also used), catalytic slurry, etc. Oxidized asphalt production relies on chemical reactions, while propane deasphalting units use solvent extraction; atmospheric and vacuum distillation units primarily employ physical separation based on the different volatilities of the mixtures.
Heavy traffic asphalt is not used for producing gasoline or diesel; gasoline and diesel are produced through atmospheric and vacuum distillation, using the same facilities. This is just my personal opinion; I hope those with more experience can correct me
Can the vacuum residue produced by atmospheric and vacuum distillation units be used directly as heavy-duty paving asphalt? I was involved in a heavy traffic asphalt project, which is essentially a vacuum distillation unit.
In fact, both vacuum distillation units and atmospheric-vacuum distillation units can produce asphalt, depending on the properties of the crude oil used as feedstock. The main operations involve checking whether the vacuum level meets the requirements, ensuring that each side stream is suitable for extraction, and controlling the quality of the asphalt, particularly parameters such as penetration and softening point. For reference only!
What chemicals are required in the process of producing heavy traffic asphalt? What are the key parameters to consider for production control? If a atmospheric and vacuum distillation unit is used to produce road asphalt, then is this process considered a chemical reaction or physical separation?
