Show.
1 blank oil physical property measurement result of table
The oily 30 DEG C of viscosity test results of 2 blank of table
Steps are as follows for specific experiment:
Step 1, the pretreatment of crude oil:
The sealed glass jars that a batch fills oil sample are put into water-bath, standing is heated to 80 DEG C, and constant temperature 2h, makes former in bottle
Oil reaches uniform state by the warm-up movement of molecule, is then allowed to stand cooled to room temperature, it is smaller to be stored in environmental temperature fluctuation
Local 48h or more, then it is assumed that the oil sample is the identical basic oil sample of composition state.
Step 2, the preheating of oil sample:
Program-controlled water-bath is opened, oil storage tank is heated to test 30 DEG C of temperature used, the control panel to program-controlled water-bath indicates
When temperature reaches 30 DEG C, constant temperature 10min.It is through pumping that the experiment oil after preheating is defeated into oil storage tank from oil inlet, until liquid level
When reaching storage tank height 1/2, stop oil inlet.Constant temperature 30min makes the oil sample in vial reach uniform by the warm-up movement of molecule
State.
Step 3, bottom settlings object is added:
Oil storage top ends of cans is opened, the deposit prepared is equably contained in tank bottom, covers top cover.
Step 4, deposit is stirred:
Start the centrifugal pump of feed line, tank center rotary nozzle drives turbine rotation, and benefit by oil pump transporting oil
With transmission device driving fuselage rotation, oil product, to be ejected into tank at a high speed, forms injection stream by nozzle.It is controlled by regulating valve
Oil inlet speed observes the reading that turbine flowmeter is shown in real time, makes speed of agitator control in 800r/min.
Step 5, temperature measurement is glued:
The viscosity of different layers position oil product is measured by in-line viscometer and is made a record.
Step 6, it separates and fills sample:
After mixing time, with filtered through gauze slurries, undissolved bottom settlings amount of substance, and the liquid that will be filtered out are weighed
Oil sample is quickly charged with the measuring cylinder (the reference mark line height that oil sample is filled to measuring cylinder) of Anton Paar rheometer.
Step 7, condensation point is tested:
Remaining filtrate is encased in the condensation point test tube having had been warmed up, its condensation point is tested, to guarantee each to be encased in
The consistency of sample condensation point in rheometer.
Step 8, the measurement of wax precipitation point, paraffin content:
The style prepared is packed into the dry pot of aluminum, is put into DSC instrument, the measurement of wax precipitation point and paraffin content is carried out.
The result of the bottom settlings object of blank crude oil dissolution of different nature is as shown in table 3 below；Heterogeneity blank crude oil
Physical property measurement result is as shown in table 4 below after dissolving tank bottom sediment；Viscosity after heterogeneity blank crude oil dissolving tank bottom sediment
Test result is as follows shown in table 5.
Dissolubility test result of the 3 heterogeneity blank oil of table to bottom settlings object
Physical property measurement result after 4 heterogeneity blank crude oil dissolving tank bottom sediment of table
Viscosity test results after 5 heterogeneity blank crude oil dissolving tank bottom sediment of table
Fig. 6 is for heterogeneity blank crude oil to the dissolution rate of bottom settlings object with paraffin content change curve, Fig. 7 heterogeneity
Blank crude oil is to the dissolution rate of bottom settlings object with viscosity change curve.By Fig. 5 a- Fig. 5 c, Fig. 6 it is found that in treatment temperature, stirring
Mix revolving speed, mixing time and bottom settlings object hardness it is certain under conditions of, blank wax content in crude oil less, viscosity it is lower, then it is former
Oil is better to the dissolubility of bottom settlings object.
Fig. 8-Figure 11 be respectively 1#, 2#, 3# and 4# oil blank crude oil incorporation bottom settlings object after viscosity with shear rate
Change curve.It is glued it is found that being formed by slurry viscosity after different blank crude oil incorporation bottom settlings objects with crude oil by Fig. 8-Figure 11
The difference of degree reduces with the variation of oil property, this is primarily due to, and oil property is poorer, the bottom settlings object of crude oil dissolution
It is fewer, thus physical property variation is small.
