Asphalt oxidation process using liquid jet ejection

Provided is a process for increasing the softening temperature of asphalts by use of liquid jet ejector with a diptube connected to the discharge connection of the liquid jet ejector for ejecting an air/asphalt mixture below a liquid level in an oxidizer vessel. The liquid jet ejector is used as bot...

Zusammenfassung:	Provided is a process for increasing the softening temperature of asphalts by use of liquid jet ejector with a diptube connected to the discharge connection of the liquid jet ejector for ejecting an air/asphalt mixture below a liquid level in an oxidizer vessel. The liquid jet ejector is used as both an air compressor and an air/oil mixer. The liquid jet ejector motive fluid is hot asphalt and the entrained vapor is air. The combined liquid jet ejector with a diptube process provides for an improvement in asphalt air blowing efficiency by requiring less cumulative air to produce a given asphalt softening temperature.
