Abstract: A process for increasing the softening point of asphalt using an eductor, preheated asphalt is mixed with an input gas in the eductor to form a gas/asphalt mixture. The gas/asphalt mixture is conducted to a heated and pressurized oxidizer vessel via piping connected to the discharge connection of the eductor, where the piping enables a bubble flow pattern to develop therein to enable reaction of the oxygen with the asphalt. The oxygen entrained asphalt mixture is discharged from an exit port of the piping in the oxidizer vessel. The resulting oxidized asphalt product stream has a softening temperature greater than the preheated asphalt feed. The process minimizes the off-gas produced to reduce the carbon footprint.

Abstract: Systems and methods are provided for separation of particles and/or asphaltenes from heavy hydrocarbon fractions. The heavy hydrocarbon fraction can correspond to a feed including particles or a processing effluent that includes particles. If the heavy hydrocarbon fraction is mixed with lower boiling fractions, a separation can be performed to reduce or minimize the amount of hydrocarbons that are present in the heavy hydrocarbon fraction. The heavy hydrocarbon fraction can then be mixed with a sufficient amount of a separation solvent to cause a phase separation. One phase can correspond to the separation solvent plus a portion of the hydrocarbons. The other phase can correspond to hydrocarbons rejected by the separation solvent plus the particles from the heavy hydrocarbon fraction. The phases can then be separated from each other using a solids-liquid centrifugal separator.
