JET PUMP SYSTEM FOR FORMING AN AQUEOUS OIL SAND SLURRY

摘要

As-mined oil sand is crushed to -5 inch by a sequentially arranged pair of double roll crushers. The crushed oil sand is fed into a hopper feeding a jet pump. Water or recycled slurry is fed under pressure as motive fluid to the jet pump. The motive fluid jet(s) produced internally by the jet pump are operative to fluidize the oil sand and the components of the slurry mix turbulently in the jet pump's tubular mixer. It is found that the slurry issuing from the jet pump is aerated and largely free of lumps.
