Title: Oil sand slurrying treatment method
Inventor: WEI JIANZHI
IPC: C10G1/00
Filed: 2019-03-29
Abstract: An oil sand slurrying treatment method: subjecting oil sand ore to primary sorting and sending to a mixer, and adding 10%-80% of solvent oil; heating during the mixing process, separating the slag and stone of the obtained oil sand slurry by means of mechanical sieving, and sending to a pulveriser for further grinding and homogenisation. The obtained liquid state material solves the problem that oil sand easily bonds into blocks, and can also be pumped through a pipeline; the transportation method is flexible and convenient, does not raise dust, and does not pollute the environment, and pipeline transportation is more conducive to thermal insulation, reducing system heat loss. During the slurrying process, the oil sand particle size decreases to a micron level, accelerating the subsequent pyrolysis and dry distillation reaction speed and increasing reaction efficiency, such that the subsequent pyrolysis and dry distillation of the oil sand is no longer limited to traditional fixed bed or moving bed processing formats; more advanced and mature processing formats such as fluidised beds can be used, providing more possibilities for the processing and utilisation of oil sand resources.
