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.

A catalyst regeneration energy recovery heat pump system is formed by adding a dual-energy compressor (24) to replace the compressor (3) and adding an expander (25) to replace the expander (5) in any of the catalyst regeneration energy recovery heat pump systems described in claims 1-18, thereby forming a catalyst regeneration energy recovery heat pump system.
