Method and apparatus for recovery of lost diluent in oil sands extraction tailings

摘要

A method of solvent recovery from oil sand extraction plant tailings, using 180 degree opposing steam-assisted accelerating nozzles, impacting on each other's high velocity jets, thus creating an impact area at the point of collision, creating an exceedingly large number of small droplets having a very large surface area exposed to the depressurized environment inside the vessel in which the nozzles are mounted. The diluent thus escaping from the tiny droplets is collected from the vessel space and recovered by condensation in a surface condensor and returned to the process.
