The sedimentary rock of pitch or other mink cell focuses.World economy to energy demand be continuously increased and the continuous consumption of conventional oil resource
Receive more and more attention non-conventional oil resource；In addition International Petroleum Price is hovered in a high position for a long time, oil-sand will be in future
It will be occupied an important position in energy resource structure.China's oil-sand resource is abundant, and oil-sand geological resources are 59.7 hundred million tons, mining resources
Amount is 22.58 hundred million tons.China's oil-sand is widely distributed, oil content is medium, oily preferable, and exploration prospect is very considerable.Have in China
For a little area oil-sand oil contents 12% or more, oil product is preferable, carries out in-depth study, reasonable development and utilization to oil-sand resource,
There is important strategic importance to Chinese energy safety.
Oil-sand exploitation is there are two types of method: the oil-sand mine buried for underground, usually to underground inject steam or hot-air,
Even solvent makes oil-sand viscous crude reduce viscosity, have mobility, can separate from gravel (solid mineral grain), then use
It is pumped to ground, this extracts heavy oil process for the underground of oil-sand on the spot.Oil-sand mine close to earth's surface be usually have an opencast mining of it is fuel-displaced
Sand, then separated viscous crude and gravel using oil sand separation technology on ground.The main of pitch is extracted from opencast oil-sand
Method has thermokalite washing process, solvent extraction technology, thermal cracking process etc. several, (application number 201510999342.3, Yi Zhongqin
The method of aqueous reversible solvent assisting oil-sand separation；A kind of oil sand continuous separation process of 201410699046 .7 of application number；Application
Number a kind of oil-sand Atmospheric vacuum destructive distillation complex solvent extraction device and method of 201510245619 .3).Industrial use is compared at present
Mature is thermokalite WATER-WASHING METHOD, which first crushes oil-sand, be re-fed into heat alkali liquid and be mixed, then into mixed serum
Being passed through gas makes in pitch flotation, after collecting pitch and alkane dilution being added to reduce its viscosity, is sent to refinery and is refined
Obtain various oil products.The technical operation is simple, but has the disadvantage that and technical bottleneck: water consumption is big, energy consumption is high, at tailing
Manage that extremely difficult, environmental pollution is serious.The method for separating pitch in the slave oil-sand of environmental protection, economy, sustainable development is found to compel
In the eyebrows and eyelashes.
