Problems with heavy traffic asphalt
Thread Content
Can the vacuum residue produced by atmospheric and vacuum distillation units be used directly as heavy traffic asphalt? Is it related to crude oil and process conditions? I was involved in a heavy traffic asphalt project, which is essentially a vacuum distillation unit.
I want to know that too; I hope someone knowledgeable can answer
Generally, the vacuum residue produced by vacuum distillation units cannot be used directly as heavy traffic asphalt and requires further processing.
A pressure reduction unit with a single tower and single furnace, capable of producing heavy traffic asphalt. The key to whether asphalt can be produced lies in whether the properties of the crude oil are suitable for producing heavy traffic asphalt. Secondly, whether the vacuum distillation column can extract the light components, whether the vacuum level is sufficient, and whether each side stream meets the process requirements, etc. This process is very mature. Last year, our company was in production for nearly a year.
Yes, we have produced it before. However, decompression is required during deep drawing, and the process parameters need to be adjusted. As mentioned above, the key issue is whether your oil is suitable for producing heavy-duty asphalt ? It is necessary to conduct an analysis of the properties of the crude oil; its density should be at least around 0.9. Otherwise, it’s not possible to produce heavy traffic asphalt. If that’s not the case, then additional treatment equipment is required. The company that manufactures our heavy traffic asphalt equipment treats iron as if it were raw material
To produce high-quality heavy traffic asphalt, good raw materials are necessary, that is, high-quality crude oil. The asphalt produced in our factory is obtained through desulfurization and extraction, and it seems to sell well, especially during the early part of the year.
