Abstract
A process for separating and purifying the oil slurry thrown out centrifugally in catalytic cracking procedure includes temp regulation, flow control and separating and purifying in high-temp centrifugal separator to obtain purified oil with the solid content less than 0.02% and the solid removing rate more than 92-98%. Its advantages are simple process, possessed ground area, and no environmental pollution.
Description
The solid-liquid separation that the present invention relates to a kind of slurry oil purifies, and particularly relates to a kind of isolation of purified of catalytically cracked oil.
At home and abroad, the catalytic cracking unit externally extracting oil amount of Duo Jia refinery increases day by day, and only the annual discharging of system of China Petrochemical Industry slurry oil is nearly more than 700 ten thousand tons.For fully utilizing this part petroleum resources, to the isolation of purified of externally extracting oil, make its increment, become the developing important subject of petro-technology.
At present, domestic and international existing slurry oil isolation of purified technology mainly contains electrostatic separation method, settling methods, tamisage etc.Wherein the electrostatic separation method can realize that slurry oil purifies increment, domestic and international more employing, and effect is good.For example, reported catalytically cracked oil electrostatic separation method in " the petrochemical complex scientific and technological achievement circular " of in October, 1991 Development Dept. of China Petrochemical Industry General Co. and institute of scientific-technical information establishment.Utilize the polarized action of high tension electrostatic field, make the filled media that is in the electric field--glass sphere polarization, the granules of catalyst in the slurry oil of the medium of flowing through is adsorbed on around the point of contact between the glass sphere, make the slurry oil purification.When the absorption of glass sphere reaches capacity, glass sphere is carried out counterflush, washing fluid is taken away granules of catalyst, makes separator recover detergent power.One cover tripping device is made up of a plurality of separators, and electrical apparatus control system purifies slurry oil by the separation and the back flushing of certain these separators of programed control, and de-solid rate is more than 90%.Essential high-voltage electrical apparatus Controlling System, a plurality of separator of being equipped with of this covering device, positive covering device investment is big, complicated operation, running cost height.
The objective of the invention is provides a kind of cost low for overcoming above-mentioned shortcoming, the method for new separating, purifying and catalytic cracking slurry oil simple for process.
The present invention is catalytically cracked oil, through the interchanger heat exchange, and temperature regulation, flow control enters continous way high temperature separating centrifuge at last, finishes the isolation of purified of slurry oil.
High temperature centrifugal separator externally extracting oil separating, purifying and catalytic cracking method of the present invention has following advantage:
1, technical process is simple, less investment, and facility investment is 1/10 of an electrostatic separation method.
2, facility compact, floor space is little.
3, can realize the serialization operation, discharging automatically, free from environmental pollution.
4, the variation of catalytically cracked oil solid content is little to the effectiveness affects of high temperature centrifugal purification technology, and this law de-solid rate can reach more than the 92--98%, and the clarified oil solid content is less than 0.02%.
5, the present invention also is applicable to the solid-liquid separation in fields such as chemical industry, environmental protection, medicine, food.
Processing method of the present invention is provided by following embodiment and accompanying drawing thereof.
Accompanying drawing is a process flow sheet of the present invention.
The situation of the concrete technology that proposes below in conjunction with description of drawings the present invention.
340 ℃ slurry oil, solid content 0.2--0.6% is extracted out by the hot oil pump of separation column 1, after interchanger 2 heat exchange, by thermoswitch 3 control slurry oil temperature is 150----300 ℃, by adjustable flow controller 4, enters high temperature separating centrifuge 5 at last again, the control centrifugation time is 2--10 minute, centrifugal rotational speed is 3000----5000 γ/min, obtains behind isolation of purified, and de-solid rate reaches 92-98%, solid content enters product narrow-necked earthen jar 6 less than 0.02% clarified oil, and the dregs of fat are put into waste oil pool 7.
Lab scale continuous device separating effect of the present invention sees the following form:
| Embodiment | Slurry oil solid content inlet % | Slurry oil solid content outlet % | Treatment capacity L/h | De-solid rate % |
| ????1 | ????0.50 | ????0.01 | ????15 | ????98 |
| ????2 | ????0.21 | ????0.01 | ????15 | ????95 |
| ????3 | ????0.25 | ????0.02 | ????15 | ????92 |
