Embodiment 1

[0032] This embodiment is used to illustrate the distillation dehydration device and method provided by the present invention.

[0033] Water was added to anhydrous crude oil to obtain an aqueous sample with a water content of 5% by weight. As shown in FIG. 2 , a water-containing sample having a water content of 5% by weight was put into a retort 11 . Open distillation column heater 14, open distillation bottle heater 15 simultaneously, control distillation column heater 14 and distillation bottle heater 15 respectively by distillation column temperature controller 16 and distillation bottle temperature controller 18, make distillation bottle 11 at 2 ℃ The temperature is raised at a rate of 1 / min, and when the temperature of the distillation column 12 detected by the distillation column temperature sensor 17 is 135° C., the temperature of the distillation column 12 is maintained at 135° C. Continue to heat the retort 11, and when the temperature of the retort 11 detected by t...

Embodiment 2

[0037] This embodiment is used to illustrate the distillation dehydration device and method provided by the present invention.

[0038] Water was added to anhydrous heavy oil to obtain an aqueous sample with a water content of 5% by weight. As shown in FIG. 3 , the above-mentioned water-containing sample obtained from anhydrous heavy oil and having a water content of 5% by weight was put into a distillation flask 11 . Open distillation column heater 14, open distillation bottle heater 15 simultaneously, control distillation column heater 14 and distillation bottle heater 15 respectively by distillation column temperature controller 16 and distillation bottle temperature controller 18, make distillation bottle 11 at 2 ℃ / min rate of heating. When the distillation column temperature sensor 17 detects that the temperature of the distillation column 12 is 130° C., the temperature of the distillation column 12 is maintained at 130° C. Continue to heat the distillation bottle 11, ...

Abstract

The present invention provides a kind of distillation dewatering set and its dewatering process. The distillation dewatering set includes one distilling flask, one distilling column with heater, and one condensator. During distillation dewatering with the distillation dewatering set, the distilling column may be heated with the heater, so as to avoid condensation of water vapor in the distilling column and avoid explosive boiling in the distilling flask caused by condensed water dropping.

Description

technical field [0001] The invention relates to a distillation dehydration device and a dehydration method using the device. Background technique [0002] During crude oil evaluation or oil product analysis, if the sample contains water, it will have a direct impact on the sample determination results. For example, analytical items such as the flash point of crude oil, the viscosity of heavy oil at 100°C, and the ash content of crude oil and heavy oil cannot be carried out. Some items such as the density and freezing point of samples can be measured, but the measurement results are not accurate. Therefore, if the sample contains water, it should be dehydrated before crude oil evaluation and oil analysis. At present, the dehydration methods for crude oil, heavy oil and heavy oil generally include microwave method, ultrasonic method, centrifugation method, closed electric dehydration method, pressure kettle dehydration method and distillation dehydration method. Among them, ...
