Embodiment 1

[0021] see figure 1 , the embodiment of the present invention provides a device for producing road asphalt from super heavy oil, including a raw material pump 1, a first heat exchanger 2, a flash tower, a flash bottom pump 3, a second heat exchanger 4, a heating furnace, Reaction tower, fractionation tower, tower bottom pump 7, vacuum tower and residual oil pump 8. One end of the first heat exchanger 2 is connected to the raw material pump 1, the other end is connected to the flash tower, the bottom of the flash tower is connected to the flash bottom pump 3, and the flash bottom pump 3 is connected to the second heat exchanger 4 , the second heat exchanger 4 is connected with the heating furnace, the heating furnace is connected with the bottom of the reaction tower, the top of the reaction tower is connected with the fractionation tower, and the bottom of the fractionation tower is connected with the bottom pump 7, The tower bottom pump 7 is connected to the heating furnace,...

Embodiment 2

[0027] The embodiment of the present invention provides a method for producing road asphalt from super heavy oil, the device used in the method is the device provided in embodiment 1, and the method mainly includes the following steps:

[0028] see figure 1 , the raw material used in this embodiment is Venezuelan super heavy oil (Liaohe super heavy oil), and the Venezuelan super heavy oil with a temperature of about 85-90 ° C is sent to the first heat exchanger 2 for heat exchange after the raw material pump 1 boosts the pressure. After heating to a temperature of 187°C, it is sent into the flash tower from below the flash tower. The oil and gas at the top of the flash tower is condensed by the flash top oil-gas air cooler (not shown in the figure), cooled to 40°C by the flash top oil-gas aftercooler (not shown in the figure), and then enters the flash top oil-water separation tank (not shown in the figure) ) to carry out gas-liquid separation, and the flash bottom oil is obt...

Abstract

The invention discloses an apparatus and a method for producing road petroleum asphalt from ultra heavy oil, and belongs to the field of petroleum refining process. The apparatus comprises a first heat exchanger, wherein one end of the first heat exchanger is connected with a raw-material pump; the other end of the first heat exchanger is connected with a flashing tower, wherein the tower bottom of the flash tower is connected with a flash bottom pump; the flash bottom pump is connected with a second heat exchanger; the second heat exchanger is connected with a heating furnace; the heating furnace is connected with the bottom of a reaction tower; the top of the reaction tower is connected with a fractionating tower; the bottom of the fractionating tower is connected with a tower bottom pump; the tower bottom pump is connected with the heating furnace; the heating furnace is connected with a vacuum tower; and the vacuum tower is connected with a residual oil pump. Visbreaking of the ultra heavy oil can be realized and heavy traffic paving asphalt with good performance can be produced through process combination of visbreaking and vacuum distillation.

Description

technical field [0001] The invention relates to a petroleum refining and processing technique, in particular to a technique for producing road petroleum asphalt from super heavy oil. Background technique [0002] As the proportion of heavy oil in petroleum processing raw materials increases year by year, the demand and product price of heavy traffic asphalt in the road petroleum asphalt market are also rising. Therefore, in order to maximize economic benefits, the process of producing road petroleum asphalt from heavy oil should be vigorously developed. [0003] At present, distillation is often used to produce road asphalt. The raw materials for petroleum processing pass through the atmospheric and vacuum distillation device, and the road petroleum asphalt is directly extracted from the bottom of the vacuum tower. [0004] In the process of realizing the present invention, the inventors found at least the following problems in the prior art: the existing vacuum distillati...
