Description
Technical field
The present invention relates to petroleum refining and separation technology field more particularly to a kind of oil sands bitumens based on the extraction of thermokalite water
Extraction element and method.
Background technology
Oil-sand is a kind of unconventional energy resource risen in recent years, because it contains bitumen therefore is also designated as pitch
Sand.Oil-sand is mostly black or grey black, is a kind of mixture by material compositions such as sand grains, pitch, clay particles, mean containing
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
Non-conventional oil resource is set to receive more and more attention；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, and in-depth study, rational development and utilization are carried out to oil-sand resource,
There is important strategic importance to Chinese energy safety.
There are two types of methods for oil-sand exploitation：For the oil-sand mine that underground is buried, typically to underground inject steam or hot-air,
Even solvent makes oil-sand viscous crude reduce viscosity, have mobility, can be separated from gravel (solid mineral grain), then use
It is pumped to ground, this extracts viscous crude technique on the spot for the underground of oil-sand.Oil-sand mine close to earth's surface be typically have an opencast mining of it is fuel-displaced
Sand, then detached 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 technologies of 201410699046 .7 of application number；Application
A kind of number oil-sand Atmospheric vacuum destructive distillation complex solvent extraction device and methods of 201510245619 .3）.Industrial use is compared at present
Ripe 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, at high energy consumption, tailing
Manage that extremely difficult, environmental pollution is serious.The method for finding separation pitch in the slave oil-sand of environmental protection, economy, sustainable development is compeled
In the eyebrows and eyelashes.
