Oxidized bitumen production plant

The utility model relates to a device for integrated production of oxidized bitumen and viscosity-reduced residual oil, which comprises an oxidizing reaction tower, a cooling fractionating tower, a water cooler, an oil-water separating tank, a water-sealed tank, a dirty oil tank, a centrifugal pump, valves and pipelines. The utility model adopts the integration of oxidized bitumen and viscosity-reduced residual oil production devices, so as to greatly reduce project investment, realize more flexible control of product categories during the daily operation process, and save much high-grade heat, thereby achieving good effects in low energy consumption and economic benefits.

Oxidized bitumen refinning process

Currently oxidized bitumen oil refining process, visbreaking residue production is the use of two different sets of processing equipment can produce qualified products according to different market and season demand. However, this production is not only big investment, but also waste a lot of high quality heat. Utility Model Content The utility model is aimed for the deficiencies of the prior art to provide a small investment and saving that is oxidized bitumen viscosity reducing heat and residue integration of production equipment. The technical proposal is: comprising an oxidation reaction tower, cooling fractionator, water, oil and gas separation tank, water sealing, sewage tanks, pumps, valves and piping, steam outlet and steam supply piping connected to the oxidation tower, oxidation reaction and water outlet pipe connected to the tower, the oxidation reaction tower outlet and air supply piping, oxidation tower vacuum residue outlet conduit connected to a source of vacuum residue, oxidation reaction tower outlet switching valve and asphalt residuum input pipe connection, asphalt residuum fractionation inlet duct switching valve and a first output terminal connected to the cooling fractionator, oil and gas outlet conduit of the second output terminal of the asphalt residuum way switching valve is connected with the cooling fractionator, the asphalt residue The second output of the switching valve the other way and water cooler inlet pipe connection, water all the way to the outlet pipe connected to the input port of the gas separation tank, the outlet between the water and the water sealing another way input port There are series of oil and gas valves and pipe connections, gas separation tank of waste oil discharge port and the gas separation tank of waste oil delivery pipeline connecting the centrifugal pump, oil separator tank also has a methane gas outlet pipe, water sealing of waste oil row inlet pipe connected to the tank outlet and sewage, sewage tank outlet and the sewage tank 3 waste oil delivery centrifugal pipe connections; cooling fractionator outlet pipe connections and finished centrifugal pumps; the sewage tank of waste oil delivery centrifugal pump also has a sewage tank of waste oil delivery output tube, finished centrifugal pumps finished output tubes, the gas separation tank of waste oil delivery centrifugal pump also has oil and gas separation tank waste oil output delivery pipe. The bitumen residue changeover valve is three-way valve; the upper water sealing is also provided with the oil and gas discharge tube. The utility model by oxidation of asphalt, reducing the sticky residue plant integration, not only reducing the large investment projects, in the course of their daily operations more flexible product range adjustment, saving a lot of high-quality heat in energy saving and economic benefits We have a very good effect. Brief Description 1 is a schematic structure of the utility model.

Descreaption of oxidation of bitumen

Below in conjunction with the accompanying drawings described in detail by way of example: As shown in the drawings, the oxidation reaction column steam with a steam supply port 1 connected to the pipe 5, and the oxidation reaction water outlet pipe 2 connected to the column 5, the oxidation reaction column 5 is connected with the outlet air duct source 3, the oxidation reaction column 5 vacuum residue vacuum residue source port and 4 pipe connection, the oxidation reaction tower outlet and asphalt residue conversion valve 5 connected to the input end of the pipe 13, asphalt residuum conversion output and the cooling valve c fractionator 13 6 fractionating inlet duct connection, b the output of bitumen residue of the way changeover valve 13 is connected to the cooling fractionator and gas outlet pipe 6, asphalt residuum conversion output of the other way valve b and 13 water-cooling pipe 14 is connected to the input port , water all the way to the output port 14 is connected to the gas separation tank inlet pipe 12, there are series of oil and gas pipeline connection between the valve 15 and the output port 14 water coolers and water sealing another way input port 11, the gas separation tank waste oil discharge port and the gas separation tank of waste oil 12 delivery pipeline centrifugal pump 8 is connected, the gas separation tank also has a methane gas outlet pipe 16 on 12, water sealing ll waste oil and sewage discharge outlet of the tank 10 inlet pipe connection, sewage tank outlet and the sewage tank of waste oil 10 9 delivery centrifugal pipe connections; cooling fractionator outlet centrifugal pumps and finished 6 of 7 pipe connections. Sewage tank waste oil delivery centrifugal pump 9 also has a sewage tank of waste oil delivery outlet pipe 19, finished product output centrifugal pumps 7 pipe 18, the gas separation tank of waste oil delivery centrifugal pump 8 is also provided There the gas separation tank of waste oil delivery outlet pipe 17. The bitumen residue changeover valve 13 is three-way valve; the upper water sealing 11 is also provided with the oil and gas discharge tube 20. When using the utility model, the production of oxygenated bitumen, asphalt residue flip the switch valve 13 to a communication with the b, a and c is closed, and the valve 15 is open and gas is oxidized asphalt production, while production visbreaking residue, flip asphalt residue changeover valve 13 to a communication with the c, a and b closed, and the valve 15 is closed and gas production residue visbreaking realized in a device is oxidized asphalt and residual oil visbreaking Production reached to reduce investment and energy saving purposes.
