Abstract

The invention provides a suspended bed hydrogenation discharge system, which comprises a suspended bed hydrogenation reactor, wherein the top portion of the suspended bed hydrogenation reactor is connected to a reaction product pipeline, the bottom portion of the suspended bed hydrogenation reactor is connected to a reaction material inlet pipeline and a discharge pipeline, the discharge pipelineis connected to a cooling separation system, and the cooling separation system is respectively connected to a torch system and a raw oil recycling system. According to the present invention, the liquid phase and the catalyst solid in the suspended bed hydrogenation reactor are rapidly discharged during the emergency discharge to stop the occurrence of the reaction and ensure the uniform density ofthe reaction material in the reactor, such that the heavy component deposition phenomenon cannot occur, the thermal runaway of the suspended bed hydrogenation reactor can be avoided, the temperaturein the reactor can be effectively controlled, the safety can be improved, the pressure of the suspended bed hydrogenation reactor can be stabilized at the high pressure, the equipment fatigue caused by the frequent pressure increase and pressure reduce can be avoided, and the energy consumption and the cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of petrochemical industry, and in particular relates to a suspension bed hydrogenation release system. Background technique [0002] As crude oil becomes heavier and thicker, the demand for light oil products continues to increase, and domestic environmental protection mechanisms become increasingly stringent, heavy oil processing has become a major problem faced by modern refineries. At present, heavy oil processing mainly includes delayed coking, visbreaking, heavy oil catalytic cracking and heavy oil hydrogenation, but all of them have certain limitations and problems, and cannot meet the needs of improving the utilization rate of petroleum resources. Suspension bed hydrogenation process can not only process the whole distillate low-quality residual oil, but also basically has no limit on the impurity content of the processed raw materials, and can process various low-quality heavy residues such as high s...
