The process can be continuous or batch. The so-called semi-aeration process causes the production of semi-blown bitumen with suitable penetration degree and softening point 100/85 or 70/60 which is used in road making and moisture barrier of houses.
As new uses were discovered, demand for petroleum increased. Kerosene was discovered in 1853 by Abraham Gesner. A British physician, Gesner developed a process to extract the inflammable liquid from asphalt, a waxy petroleum mixture. The term kerosene is, in fact, derived from the Greek word for wax.

extractive distillation section, featuring the injection of large quantities of a solvent and a multi-stage purification process. The high solvent-to-feed ratio needed to achieve the purity specification on butadiene (>99.6%) causes large steam consumption. In addition, the final stage of the purification is
The distillation process separates the major constituents of crude oil into so-called straight-run products. Sometimes crude oil is "topped" by distilling off only the lighter fractions, leaving a heavy residue that is often distilled further under high vacuum. Table IV: 2-5. Atmospheric Distillation Process

Heated asphalt cement is mixed with residual asphaltic oil from the earlier distillation process for a slow-curing asphalt, with kerosene for medium-curing, and with gasoline or naphtha for the rapid-curing asphalt.
Only use Performance Grade (PG) Asphalt Binder meeting the requirements of AASHTO M 320 and the Combined State Binder Group Method of Acceptance for Asphalt Binder, available on the Asphalt Products page of the Approved/Qualified Products List. Use asphalt binder supplier recommendations for mixing and compaction temperatures.
Zeki Berk, in Food Process Engineering and Technology, 2009. 13.1 Introduction. Distillation is a separation operation based on differences in volatility. If a mixture containing substances that differ in their volatility is brought to ebullition, the composition of the vapors released will be different from that of the boiling liquid.

4.1 This procedure measures the amount of the more volatile constituents in cutback asphalt. The properties of the residue after distillation are not necessarily characteristic of the bitumen used in the original mixture, nor of the residue which may be left at any particular time after field application of the cutback asphalt.
This is "straight run bitumen”. This process is called bitumen production by straight run vacuum distillation. An alternative method of bitumen production is by precipitation from residual fractions by propane or butane-solvent deasphalting.
HMA Pavement Mix Type Selection Guide Introduction Background Our nation’s roadway system is critical to our economy. Hot Mix Asphalt (HMA) pavements consti-tute a large part of our nation's surfaced roads. HMA pavements serve in a multitude of traffic and environ-mental conditions, demanding that the materials and
Much has been written about crude column product separation by advanced process control (APC) but very little about vacuum column APC. Why? Vacuum distillation unit separation is important, especially in asphalt mode, when vacuum pitch is sold as a premium product, and controlling asphalt quality is high on the list of economic priorities.
