PROCESSING METHOD OF BITUMINOUS SANDS Russian patent published in 2012 - IPC C10C1/04 C10B55/08 C10G1/02 

FIELD: oil and gas industry.

SUBSTANCE: processing method of bituminous sands involves their heating in viscosity breaking mixing reactor together with its efficient mixing till homogeneous consistency is obtained. Heating is performed at 400°-500°C. After volatile fractions of oil products are liberated from the obtained product, the product with reduced viscosity is obtained. The obtained product is supplied to quick coking reactor where the obtained product flow is moved with gas jet and dispersed. At that, gas is supplied at speed of 30-40 m/sec. Coking process is performed continuously in hydrodynamic mode so that stable spouting bed is created at atmospheric pressure and temperature of 600-650°C during 1-2 seconds. After that, the formed coke is removed, and coke gases are supplied after solid particles are separated from them for separation into condensing and non-condensing component parts.

EFFECT: advanced primary treatment of raw material, reduction of coke formation time, possible heat treatment of fine particles, which allows obtaining homogeneous coke with dense structure.
