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:

[0040] 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.

[0041] Figure 1 The catalyst regeneration energy recovery heat pump system shown is implemented as follows:

[0042] (1) Structurally, it is mainly composed of a heat source regenerator, a coke-regeneration system, a compressor, a heat exchanger, an expander, a heater, a second expander, a regenerator, and a third expander. There is an external air passage that connects to the coke-regeneration system 2 via the heat source regenerator 1. The coke-regeneration system 2 also has a flue gas passage that connects to the outside via the heat exchanger 4 and the heat source regenerator 1. There is an external low-temperature heat medium passage that connects to the compressor 3. The second expander 7 has a low-temperature heat medium passage that connects to the regenerator 8 and then connects to the compressor 3 through an intermediate port. The compressor 3 also has a low-temperature heat medium passage that connects to the expander 5 via the heat exchanger 4. The expander 5 also has a low-temperature heat medium passage that connects to the heater 6 and then splits into two paths—the first path connects to the second expander 7 and the second path connects to the regenerator 8. The regenerator 8 also has a low-temperature heat medium passage that connects to the outside via the third expander 9. The heater 6 also has a heated medium passage that connects to the outside. The expander 5, the second expander 7, and the third expander 9 are connected to the compressor 3 and transmit power.

[0043] (2) In terms of process, external air flows through the heat source regenerator 1 to absorb heat and increase its temperature, and then enters the coke burning-regeneration system 2 to participate in combustion; coke forms on the surface of the air and the catalyst, and a series of processes including combustion are carried out to regenerate the catalyst and generate flue gas. The flue gas generated by the coke burning-regeneration system 2 is separated and purified and then supplied to the heat exchanger 4. The flue gas flows through the heat exchanger 4 and the heat source regenerator 1 to gradually release heat and decrease its temperature, and then is discharged to the outside; the external low-temperature heat medium enters the compressor 3 to increase its pressure and temperature, and the low-temperature heat medium discharged by the regenerator 8 enters the compressor 3 through the intermediate port to increase its pressure and temperature. The low-temperature heat medium discharged by the compressor 3 flows through the heat exchanger 4 to absorb heat and increase its temperature, flows through the expander 5 to decrease its pressure and do work, flows through the heater 6 to release heat and decrease its temperature, and then splits into two paths - the first path flows through the second expander 7 to decrease its pressure and do work, flows through the regenerator 8 to absorb heat and increase its temperature, and then passes through the heat exchanger 6 to increase its pressure and decrease its temperature. The air enters the compressor 3 through the middle intake port to increase pressure and temperature, and then enters the regenerator 8 to release heat and cool down. The low-temperature heat medium discharged from the regenerator 8 flows through the third expander 9 to reduce pressure and do work, and then is discharged to the outside. The flue gas discharged from the coke-regeneration system 2 provides the driving heat load. The air and flue gas carry away the low-temperature emission heat load through the heat source flow. The heated medium obtains the medium-temperature heat load through the heater 6, and the low-temperature heat medium provides the low-temperature heat load through the heat pump flow. The mechanical energy output by the expander 5, the second expander 7 and the third expander 9 provides power to the compressor 3, or the mechanical energy output by the expander 5, the second expander 7 and the third expander 9 provides power to the compressor 3 and the outside, or the expander 5, the second expander 7, the third expander 9 and the outside jointly provide power to the compressor 3, forming a catalyst regeneration energy recovery heat pump system.
