Description

Technical Field:

[0001] The present invention belongs to the technical fields 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 burn the coke deposited on the catalyst with air to restore the activity of the catalyst - catalyst regeneration. This process releases a large amount of thermal energy at a relatively high temperature, which 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] Based on 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 the energy for catalyst regeneration.
