Description

Technical Field:

[0001] The present invention belongs to the technical field of thermodynamics and heat pump technology. Background Art:

[0002] Catalytic cracking is a process in which heavy petroleum hydrocarbons produce light oil products such as liquefied gas, gasoline, and diesel under the action of a catalyst. When the feedstock oil undergoes catalytic cracking on the catalyst, on the one hand, products such as gas, gasoline, and diesel are generated through cracking and other reactions, and on the other hand, a condensation reaction occurs simultaneously to form coke deposited on the surface of the catalyst - this reduces the activity of the catalyst.

[0003] People use air to burn off the coke deposited on the catalyst to restore the activity of the catalyst - catalyst regeneration. A large amount of heat energy at a relatively high temperature is released during this process and should be fully utilized. Currently, the main means of recovering the energy of the regenerated flue gas is to set up a waste heat boiler to generate steam or further generate power. However, after careful analysis, the following problems are found:

[0004] (1) There is a large irreversible loss of temperature difference during the coke burning process; (2) In the utilization link, the temperature and quantity of the flue gas are not considered simultaneously; (3) The technology for utilizing the energy of the flue gas needs to be improved, and there is still a large room for improvement in both power utilization and heat supply utilization; (4) The energy recovery of the flue gas is not combined with the overall energy consumption of the oil refining production process to enhance its application value.

[0005] In line with the basic principles of simple, active, safe, and efficient energy utilization, the present invention provides a catalyst regeneration energy recovery heat pump system with a reasonable process, simple structure, and capable of realizing efficient / high-value recovery and utilization of catalyst regeneration energy.

The flue gas flows through the second generator 4, is heated, releases refrigerant vapor into it and supplies it to the second condenser 7. The concentrated solution of the second generator 4 enters the absorber 5 through the second solution heat exchanger 13, absorbs the refrigerant vapor and releases heat to the heated medium. The dilute solution of the absorber 5 enters the generator 3 through the solution heat exchanger 12, absorbs heat and releases refrigerant vapor and supplies it to the condenser 6.

[0048] (2) In terms of the process, compared with the Figure 1 catalyst regeneration energy recovery heat pump system shown, the difference lies in that the flue gas discharged from the charring-regeneration system 1 flows through the high-temperature heat exchanger 14, the second generator 4, and the heat source regenerator 2 to gradually release heat and cool down, and then is discharged to the outside; the refrigerant vapor discharged from the second generator 4 flows through the compressor 15 to increase pressure and temperature, absorbs heat and increases temperature through the high-temperature heat exchanger 14, expands and does work through the expander 16, and then enters the second condenser 7 to release heat and condense; the work output by the expander 16 provides power for the compressor 15, or the work output by the expander 16 provides power for the compressor 15 and the outside, or the expander 16 and the outside jointly provide power for the compressor 15, forming a catalyst regeneration energy recovery heat pump system.

[0051] (2) In terms of the process, compared with Figure 2 the catalyst regeneration energy recovery heat pump system shown, the difference is that the refrigerant vapor discharged from the compressor 15 absorbs heat and gradually increases in temperature when flowing through the recuperator 17 and the high-temperature heat exchanger 14, expands and does work when flowing through the expander 16, releases heat and decreases in temperature when flowing through the recuperator 17, and then enters the second condenser 7 to release heat and condense, thus forming the catalyst regeneration energy recovery heat pump system.
