Description

Technical fields:

[0001] This invention belongs to the field of thermodynamics and heat pump technology. Background technology:

[0002] Catalytic cracking is the process of producing light petroleum products such as liquefied petroleum gas, gasoline, and diesel from heavy petroleum hydrocarbons under the action of a catalyst. When feedstock undergoes catalytic cracking on a catalyst, on the one hand, it generates products such as gases, gasoline, and diesel through cracking and other reactions; on the other hand, condensation reactions occur simultaneously to generate coke deposited on the catalyst surface—which reduces the activity of the catalyst.

[0003] Catalyst regeneration involves burning away the coke deposited on the catalyst with air to restore its activity. This process releases a large amount of high-temperature heat energy, which should be fully utilized. Currently, the main method for recovering energy from regenerated flue gas is to install waste heat boilers to generate steam or further generate power. However, careful analysis reveals the following problems:

[0004] (1) There is a large irreversible loss of temperature difference in the coking process; (2) The temperature and quantity of flue gas are not considered at the same time in the utilization stage; (3) The flue gas energy utilization technology needs to be improved. There is a lot of room for improvement in both power utilization and heating utilization; (4) The flue gas energy recovery is not combined with the overall energy use of the oil refining process to enhance its application value.

[0005] Based on the fundamental principles of simple, proactive, safe, and efficient energy utilization, this invention presents a catalyst regeneration energy recovery heat pump system with a reasonable process and simple structure, which realizes efficient / high-value recovery and utilization of catalyst regeneration energy.

The coke-regeneration system (B) is adjusted so that the coke-regeneration system (B) is connected to the auxiliary combustion chamber (G) through a flue gas channel, and the auxiliary combustion chamber (G) is further connected to the high-temperature heat exchanger (2) through a flue gas channel, thereby forming a catalyst regeneration energy recovery heat pump system.

19. A catalyst regeneration energy recovery heat pump system, comprising, in any one of the catalyst regeneration energy recovery heat pump systems described in claims 1-17, an air compressor (H) and a flue gas fan (I) are added, and the external air passage is adjusted to connect the coke-regeneration system (B) via a heat source regenerator (A) to the external air passage connecting the coke-regeneration system (B) via the air compressor (H) and the heat source regenerator (A). The flue gas passage of the coke-regeneration system (B) is adjusted to connect the external air passage via a high-temperature heat exchanger (2) and the heat source regenerator (A) to the external air passage connecting the coke-regeneration system (B) via the flue gas fan (I), the high-temperature heat exchanger (2), and the heat source regenerator (A). The flue gas fan (I) is connected to the air compressor (H) and transmits power, thus forming a catalyst regeneration energy recovery heat pump system.

20. A catalyst regeneration energy recovery heat pump system is a catalyst regeneration energy recovery heat pump system according to any one of claims 19, wherein an auxiliary combustion chamber (G) is added, and an external fuel passage is connected to the auxiliary combustion chamber (G). The coke-regeneration system (B) is adjusted so that the coke-regeneration system (B) has a flue gas passage connected to the flue gas generator (I), and the auxiliary combustion chamber (G) is further connected to the flue gas generator (I) through a flue gas passage, thereby forming a catalyst regeneration energy recovery heat pump system.
