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.

Detailed implementation method:

[0048] First, it should be noted that the structure and process are not repeated unless necessary, and obvious processes are not described. The invention will now be described in detail with reference to the accompanying drawings and examples.

[0049] Figure 1 The catalyst regeneration energy recovery heat pump system shown is implemented as follows:

[0050] (1) Structurally, it mainly consists of a heat source regenerator, a coke-regeneration system, a compressor, a high-temperature heat exchanger, a high-temperature expander, a high-temperature steam generator, a low-temperature steam generator, a second compressor, a heater, a booster pump, a throttle valve, an evaporator, an ejector, a second booster pump, and a second ejector; externally, there is an air passage that connects to the coke-regeneration system B via the heat source regenerator A. The coke-regeneration system B also has a flue gas passage that connects to the outside via the high-temperature heat exchanger 2 and the heat source regenerator A. Externally, there is a gas passage that connects to the compressor 1. The compressor 1 has a gas passage that connects to the high-temperature expander 3 via the high-temperature heat exchanger 2. The high-temperature expander 3 also has a gas passage that connects to the high-temperature steam generator 4 and the low-temperature steam generator 5 before connecting to the outside. The second compressor 6 has a refrigerant vapor passage that connects to the heater 7. The heater 7 also has a condensate pipeline that connects to the booster pump 8 and... The low-temperature steam generator 5 is connected to the heater 7, and the condensate pipeline is connected to the evaporator 10 via the throttle valve 9. The evaporator 10 also has a refrigerant vapor channel connected to the low-pressure steam inlet of the ejector 11. The low-temperature steam generator 5 also has a steam channel connected to the high-pressure steam inlet of the ejector 11. The ejector 11 also has a medium-pressure refrigerant vapor channel connected to the second compressor 6. An external liquid medium pipeline is connected to the high-temperature steam generator 4 via the second booster pump 12. The high-temperature steam generator 4 then has a steam channel connected to the high-pressure steam inlet of the second ejector 13. An external heated medium channel is connected to the heater 7 and then to the low-pressure steam inlet of the second ejector 13. The second ejector 13 also has a user steam channel connected to the outside. The evaporator 10 also has a low-temperature heat medium channel connected to the outside. The high-temperature expander 3 is connected to the compressor 1 and the second compressor 6 and transmits power.

[0051] (2) In terms of process, external air flows through heat source regenerator A to absorb heat and increase its temperature, and then enters coke burning-regeneration system B to participate in combustion; coke forms on the surface of the air and catalyst, and a series of processes including combustion are carried out to regenerate the catalyst and generate flue gas. The flue gas generated by coke burning-regeneration system B and after separation and purification are provided to high-temperature heat exchanger 2. The flue gas flows through high-temperature heat exchanger 2 and heat source regenerator A to gradually release heat and decrease its temperature, and then is discharged to the outside; external gas flows through compressor 1 to increase its pressure and temperature, flows through high-temperature heat exchanger 2 to absorb heat and increase its temperature, flows through high-temperature expander 3 to decrease its pressure and do work, and flows through high-temperature expander 3 to increase its pressure and temperature. The warm steam generator 4 and the low-temperature steam generator 5 gradually release heat and cool down before being discharged to the outside. The refrigerant vapor discharged from the second compressor 6 enters the heater 7 to release heat and condense, and then splits into two paths—the first path flows through the booster pump 8 for pressurization and then enters the low-temperature steam generator 5 to absorb heat and vaporize; the second path flows through the throttling valve 9 for depressurization and cooling before entering the evaporator 10 to absorb heat and vaporize. The steam generated by the low-temperature steam generator 5 enters the ejector 11 through the high-pressure steam inlet. The high-pressure steam flows through the nozzle to reduce pressure and increase speed, forming a low-pressure zone. The refrigerant vapor generated by the evaporator 10 is drawn into the low-pressure zone of the ejector 11. The two paths of steam... After the steam and gas are mixed, the vapor flows through a diffuser to slow down and increase in pressure, forming medium-pressure refrigerant steam. It then enters the second compressor 6 for further pressurization and heating. The heated medium flows through the heater 7 to absorb heat and vaporize. The liquid medium flows through the second booster pump 12 for pressurization, then flows through the high-temperature steam generator 4 to absorb heat and vaporize. It then enters the second ejector 13 through the high-pressure steam inlet. The high-pressure steam flows through the nozzle to slow down and increase in pressure, forming a low-pressure system. The steam generated by the heater 7 is drawn into the low-pressure zone of the second ejector 13. After the two steam streams mix, they flow through the diffuser to slow down and increase in pressure, forming medium-pressure steam, which is then supplied to the users. The smoke emitted by the coke-regeneration system B... The gas provides the driving heat load. Air and flue gas carry away the low-temperature emission heat load through the process of entering and exiting the heat source. The gas carries away the emission heat load through the process of entering and exiting the heat pump. The low-temperature heat medium provides the low-temperature heat load through the evaporator 10, and the user obtains the steam-type heat load. The mechanical energy output by the high-temperature expander 3 is used to power the compressor 1 and the second compressor 6, or the mechanical energy output by the high-temperature expander 3 is used to power the compressor 1, the second compressor 6 and the outside, or the high-temperature expander 3 and the outside jointly provide power to the compressor 1 and the second compressor 6, forming a catalyst regeneration energy recovery heat pump system.
