Embodiment 1

[0081] Use as attached figure 1 In the phase balance measurement and separation device shown, the balance space in the balance main kettle has an inner diameter of 80mm and a height of 100mm, and the window is a sapphire cylinder with an inner diameter of 10mm and a height of 30mm. The inner diameter of the balance auxiliary kettle is 100mm, and the height is 100mm. The residual oil used was obtained from Wuhan Branch of China Petroleum & Chemical Corporation, and its properties are shown in Table 1.

[0082] Utilize negative pressure to inhale the residual oil 120g after heating in the balance main kettle 8; Utilize the high-precision plunger pump 1 to press the n-butane solvent in the solvent tank 3 into the balance main kettle 8, record the n-butane solvent feed temperature, Pressure and volume: Heat the balanced main kettle 8 to the reaction temperature of 120°C and keep it warm, start stirring, set the 8 pistons of the balanced main kettle to the pressure holding mode of...

Embodiment 2

[0085] The phase balance measurement and separation device, residual oil raw material, and implementation steps used are the same as those in Example 1, except that the stirring time is 4 hours.

Embodiment 3

[0087] The phase balance measurement and separation device, residual oil raw material, and implementation steps adopted are the same as those in Example 1. The difference is that the test solvent is n-pentane, the test temperature is 220° C., and the test pressure is 16 MPa. The obtained phase balance data are listed in the table 2.

Description

technical field [0001] The invention belongs to the field of chemical engineering, and relates to a high-temperature, high-pressure, visually adjustable volume phase balance measurement and separation device and a use method thereof. Background technique [0002] Solvent deasphalting technology is one of the important technologies for lightening heavy oil, and its combined process is an attractive development direction for the maximum processing and utilization of heavy oil. Solvent deasphalting is a physical process of liquid-liquid extraction, which is separated according to the different solubility of the solvent to the components in the residue. Although the industrialization of solvent deasphalting process has a long history, due to the extremely complex composition of residual oil, the properties of residual oil from different sources are very different. In order to accurately predict the yield and product properties of deasphalted oil, a reliable basic design is provi...
