Difficult issues regarding the processing and production of asphalt products
Thread Content
Question: 1. Which crude oils are suitable for producing high-quality straight-run asphalt? 2. The penetration ratio is not appropriate; how to adjust it on a constant-pressure device? I would like to ask all the teachers for advice.
We have produced 70# and 90# road asphalt using various types of crude oil, such as Iranian heavy crude, Kuwaiti crude, Saudi Intermediate crude, and Saudi Heavy crude. The results were quite satisfactory; in all cases, the asphalt was produced directly from the vacuum distillation system.
