Description

Technical field:

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

[0002] Catalytic cracking is the process of producing light oil products such as liquefied gas, gasoline and diesel from heavy petroleum hydrocarbons under the action of catalysts. When crude oil is catalytically cracked on the catalyst, on the one hand, gas, gasoline, diesel and other products are generated through cracking and other reactions, and on the other hand, condensation reactions occur at the same time to generate coke deposited on the catalyst surface, which 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. This process releases a large amount of heat energy at a high temperature, which should be fully utilized. The main means of recovering the energy of 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 were found:

[0004] (1) There are large temperature differences and irreversible losses in the charring process; (2) In the utilization stage, the temperature and quantity of the flue gas are not considered simultaneously; (3) The flue gas energy utilization technology needs to be improved, and there is a lot of room for improvement in both power utilization and heat utilization; (4) The flue gas energy recovery is not combined with the overall energy consumption of the refining production process to enhance its application value.

[0005] Based on the basic principle of realizing energy utilization in a simple, active, safe and efficient manner, the present invention provides a catalyst regeneration energy recovery heat pump system with a reasonable process and a simple structure, which realizes efficient / high-value recovery and utilization of catalyst regeneration energy.
