Description
Technical field
The present invention relates to oil-sand acquisition technique, belong to the oil-sand treatment agent for making the crude oil sand particle being broken split into thin oil-sand particle in slurry state, the particularly agent of moisturizing type oil-sand pulp dissociation.
Background technology
Oil-sand is referred to as " tar sand ", " heavy oil sand " or " Tar sands ", is a kind of mixture by pitch, sand grains, rich ore clay and water, and its bitumen content is 7%-14%, and the mineral such as sand and clay account for 80%-85%, aqueous 3%-6%.The oil-sand resource reserves of China reach hundred billion tons through preresearch estimates, are important non-conventional oil resources.The exploitation of oil-sand is concentrated mainly on mining type and how coal tar is extracted from oil-sand.Mainly there are three kinds according to the oil-sand separation technology that oil-sand structure difference is used：Solvent extraction, pyrogenation and carbonization method and heat chemistry WATER-WASHING METHOD.General glossy type oil-sand is suitable to organic solvent extract and separate or pyrogenation and carbonization is separated.The problem of there is low solvent recovering rate and environmental pollution due to solvent extraction, and pyrogenation and carbonization method technique is immature, cost is higher, so, this solvent extraction and pyrogenation and carbonization method commercial Application are less, rest essentially within the desk research stage.Moisturizing type oil-sand is suitable to heat chemistry WATER-WASHING METHOD, i.e., in the presence of surfactant and alkali, realizes the stripping of oil and sand.Oil-sand heat chemistry WATER-WASHING METHOD because technique is simple, cost is low and water reagent reusable edible obtain extensive industrial applications.Influenceing the technical factor of oil-sand heat chemistry water-washing technique effect includes the technical factors such as washing medicament, washing temperature, water sand mass ratio, influence of the sand grains particle diameter to oil-sand heat chemistry water-washing technique effect is also most important, show as sand grains particle diameter smaller, hot wash effect is better.At present, external shallow-layer oil-sand（Oil-sand buried depth is less than 75 meters）Exploitation is based on outdoor excavation, and its oil-sand block character difference in size excavated greatly, needs fully to crush it before processing.Usually using routine mine Hubei Province formula, roll crushing machine equipment is crushed to oil-sand block, its operation principle is that disintegrating machine executing agency implements to extrude to oil-sand, shear and jettisoning, oil-sand is set to be crushed under external force, this operation principle is more effective for the solid mineral with certain structural strength, but have thixotropic soft solid class material effect undesirable for oil-sand is this kind of, particularly after oil-sand block particle diameter is crushed to 5cm-8cm, oil-sand can produce compacting when being sheared again by external force, creep, pitch will be bonded on the crushing mechanism execution unit of equipment with sand, make disintegrating machine moving component stuck, continuous oil-sand crushing operation can not be carried out, and then minimum requirement of the heat chemistry WATER-WASHING METHOD to oil-sand sand grains particle diameter can not be met.
The content of the invention
Agent is dissociated it is an object of the invention to provide a kind of moisturizing type oil-sand pulp, physicochemical stability is stronger, can effective for the moisturizing type oil-sand crossed by fine crushing pulp, requirement of the subsequent thermal chemistry washing to moisturizing type oil-sand sand particle size can not only be met, but also the separating effect of oil and sand can be improved.
The object of the present invention is achieved like this：A kind of moisturizing type oil-sand pulp dissociates agent, including bleeding agent, mineral oil, asphalt emulsifier, remover, pH value conditioning agent and water, bleeding agent constitutes A type mixtures with mineral oil, weight/mass percentage composition of the bleeding agent in A type mixtures is 0.020%-0.025%, bleeding agent is made up of Oep-70 with Aep-98, and the ratio of Oep-70 quality and Aep-98 quality is (10 ﹕ 13)-(1 ﹕ 1)；Asphalt emulsifier, remover, pH value conditioning agent constitutes Type B mixture with water, weight/mass percentage composition of the asphalt emulsifier in B type mixtures is 0.2%-0.4%, asphalt emulsifier is made up of Span-80 with Tween-80, the ratio of Span-80 quality and Tween-80 quality is (1 ﹕ 12)-(1 ﹕ 8), weight/mass percentage composition of the remover in B type mixtures is 0.005%-0.010%, remover is dodecyl benzyl dimethyl ammonium chloride, the mixture that myristyl benzyl dimethyl ammonium chloride is mutually mixed into any one pure substance among hexadecylpyridinium chloride three or the three by any combination mode with any mass ratio, weight/mass percentage composition of the pH value conditioning agent in B type mixtures is 0.3%-0.5%, pH value conditioning agent is sodium hydroxide, sodium carbonate, sodium acid carbonate, sodium phosphate, sodium tripolyphosphate and any one pure substance among sodium metasilicate or the mixture being mutually mixed into any mass ratio by any combination mode, mineral oil is diesel oil, coker gas oil, kerosene and any one pure substance among 120# solvent naphthas or the mixture being mutually mixed into any mass ratio by any combination mode.
Through largely verifying repeatedly, quality is equal to the oil-sand quality 30%-50% present invention and quality is equal to oil-sand quality and temperature for the pulp dissociation liquid of the hot water composition more than or equal to 40 DEG C and crossed by fine crushing and sand grains particle diameter is less than or equal to 5mm moisturizing type oil-sand and is fully stirred evenly and contacted with each other with the state mixed when being continuously stirred by drum mixer with 50r/min rotating speed 30min-40min with 50r/min rotating speed by drum mixer in by drum mixer, the moisturizing type oil-sand crossed by fine crushing is pulped and mutually dissociated, so that the particle diameter after its dissociation is less than 2.5mm, it is intended to reach minimum requirement of the heat chemistry WATER-WASHING METHOD to moisturizing type oil-sand particle diameter, strengthen cleaning performance of the heat chemistry WATER-WASHING METHOD to moisturizing type oil-sand.Follow-up heat chemistry WATER-WASHING METHOD susceptible of proof：The moisturizing type oil-sand being pulped is more beneficial for the extraction of the pitch in oil-sand.In summary, physicochemical stability of the present invention is stronger, can effective for the moisturizing type oil-sand crossed by fine crushing pulp, requirement of the subsequent thermal chemistry washing to moisturizing type oil-sand sand particle size can not only be met, but also the separating effect of oil and sand can be improved.
