Description
Technical Field
The invention relates to the field of petrochemical industry, in particular to a method and a system for accelerating aggregation of catalyst particles in oil slurry.
Background
The oil slurry is a byproduct of catalytic cracking (FCC), is rich in colloid and asphaltene, and has the characteristics of high viscosity and high density. The FCC slurry oil has good economic value, but because the FCC slurry oil contains 0.2-0.9% of catalyst powder with the diameter of less than 80 μm (micron), the slurry oil needs to be purified for economic scale and value-added utilization.
The oil slurry purification treatment technologies are roughly as follows: natural settling, chemical assistant settling, filtration, electrostatic separation, centrifugal separation, etc.
The natural settling method is the method used at the earliest, and only uses gravity to settle, but because the particles of the catalyst powder are fine (the diameter is between 1 and 80 mu m), the viscosity and the specific gravity of the slurry are both large, and the existence of the electric double layer, the efficiency is low, the period is long, the effect is poor, and the method is not applied in industry.
The electrostatic separation method cannot achieve its effect due to the fact that the surface of some parts is wrapped by oil, which is inevitably generated during the treatment process, and the centrifugal separation method has no value and example for industrial application because it is difficult to treat large batches of oil slurry.
The filtration method has high requirements on equipment, but has the problems of high investment, small operation flexibility, short operation period, short service life of a filter, high operation and maintenance cost and the like, although the filtration method is applied in industry, the filtration method is not common, and most of domestic filtration devices are used for treating shutdown states and being dismantled due to the reasons.
The chemical assistant settling method is an oil slurry purification treatment technology developed in recent years, and has the advantages of low investment, simple operation, good effect, short settling period and large treatment capacity, so the chemical assistant settling method is highly approved in the industry, and the industrial application cases are rapidly increased.
However, to achieve a better settling effect, the chemical assistant settling method usually requires a longer settling time or a larger settler, and even so, the settling effect sometimes fluctuates greatly, which affects the product yield of the clarified oil.
