Greatly, under normal circumstances in 50V or so.
Step 3: oil sample dehydration and sampling：
(1) numerical value change of control temperature system should be watched in heating process at any time, is adjusted in time according to the state of oil sample
Voltage.
A. oil sample observes its state at any time at 100 DEG C, and voltage should be turned down in time at once when oil sample spumes.Waxy crude oil
General start regulation voltage observes the change of oil sample in dehydrator in 60V or so, 100 DEG C；Emulsified crude oil is typically started shooting regulation
Voltage in case of oil sample spumes, should turn voltage down in 70V or so, 100 DEG C, and adjustable range is 4~5V or so.

Liquid phase is well mixed.Waxy crude oil easily causes punching boiling, should turn voltage down as far as possible, be even switched off if any violent fried sound；Breast
Voltage should be turned down if any fried sound by changing crude oil, and adjustable range be 5~10V, acutely fried sound not rise and be advisable that (voltage should not be adjusted too
Greatly, otherwise temperature declines).
C. when oil sample temperature rises to 180 DEG C, for regulation voltage control temperature at 180 DEG C or so, half an hour does not fry sound
And abnormal conditions can determine whether that dehydration finishes.Under normal circumstances：160 DEG C of dehydrations of waxy crude oil are finished, and 140 DEG C of light crude oil has been dehydrated
Finish.
(2) finished product samples, and oil sample temperature is cooled to 80 DEG C, prepares sampling (viscous crude can properly increase probe temperature).Act
First ready 1000mL beakers will be dehydrated the oil sample taking-up finished, and beaker bottom is gently knocked several times on the ground in time,
Ensure that the moisture of residual stays in beaker bottom.The lightweight oil component condensed in receiver should be taken out, still with small beaker simultaneously
Touch on the ground and several times, ensure that the moisture of residual stays in beaker bottom.Light crude oil is first poured into 500mL wide-mouth bottles, then
Oil sample is injected in 500mL wide-mouth bottles, unnecessary oil sample timely processing, oil sample temperature is poured into waste liquid barrel after reducing by unnecessary.
Step 4: dehydration terminates：
Regulating and controlling voltage pointer is adjusted to zero, deenergization, closes recirculated water.
The utility model method carries out dewater treatment to heterogeneity crude oil, and gained comparison data is shown in Table 1.Can by data
With crude oil water containing after finding out at this method far below standard requirement, it can be seen that oil property does not change by density, viscosity
Become.
