Where is asphalt extracted from?
Thread Content
If asphalt is to be produced, where is it extracted in the atmospheric and vacuum distillation process?
Got it, it’s oil extraction after deep pulling :(
It should come out from the bottom of the pressure relief tower
In a sense, it is vacuum residue after deep distillation; however, to obtain quality asphalt from vacuum residue, it is necessary to adjust the operations of the vacuum distillation tower. This process is greatly influenced by the properties of the crude oil – if the asphaltene content in the feedstock is low, it is not possible to produce quality asphalt. Generally, when the feedstock is heavier and has a higher asphaltene content, it is easier to produce grade A asphalt.
Bottom-depleted residue oil! It is greatly affected by the properties of the raw materials!
Reduced-pressure residue; however, when producing asphalt, the raw material needs to be changed
Different raw materials result in various names for the residue obtained at the bottom of the vacuum distillation tower in the atmospheric and vacuum distillation process. Some raw materials simply cannot be used to produce asphalt products; hence such residues have many different names. With other raw materials, high-quality road asphalt can be produced directly from the bottom of the vacuum distillation tower using atmospheric and vacuum distillation units. The production of asphalt, or that of most products, is highly dependent on the raw materials used
