Embodiment approach
[0059] As a preferred embodiment of the present invention, the heavy oil low-temperature lightening system includes a heavy oil storage tank 1, an oil inlet pipeline 2, a lightening device 4 and an oil return pipeline 5, specifically as figure 1 shown;
[0060] The heavy oil storage tank 1 communicates with the lightweight device 4 through the oil inlet pipeline 2, and the lightweight device 4 communicates with the heavy oil storage tank 1 through the oil return pipeline 5;
[0061] The oil inlet pipeline 2 is also provided with a heavy oil pump 3, which is used to pressurize the heavy oil to the inlet of the lightening device 4 and maintain a certain pressure of the heavy oil.
[0062] The present invention provides a low-temperature lightening system for heavy oil, which includes a heavy oil storage tank 1, an oil inlet pipeline 2, a heavy oil pump 3, a lightening device 4, and an oil return pipeline 5. The inlet of the lightening device 4 maintains a certain pressure, and ...
Embodiment 1
[0081] A low-temperature lightening method for heavy oil provided in this embodiment includes the following steps:
[0082] (a) Heat Tahe crude oil in the heavy oil storage tank to 50°C, pump it into the inlet of the lightening device through the heavy oil pump, and keep the inlet pressure of the heavy oil at 2.0Mpa;
[0083] (b) The heavy oil enters the lightening device for lightening treatment, and its outlet pressure is normal pressure after passing through the lightening device;
[0084] The gas product obtained after the lightening treatment is discharged, cooled to obtain light oil, and the heavy oil after the lightening treatment is subjected to the above-mentioned cycle treatment once (that is, the heavy oil undergoes two lightening treatments).
Embodiment 2
[0086] The low-temperature lightening method of heavy oil provided in this example is the same as that of Example 1, except that the Tahe crude oil is heated to 80° C. in a heavy oil storage tank. For details, please refer to Example 1.
