Embodiment 1

[0066] Test the flue gas of a certain coal-fired power plant, and balance the present invention Figures 1 to 3 The device shown in is for low concentrations of CO in the flue gas 2 The capture and recovery treatment effect of the process. The material balance results are shown in Table 1:

[0067] Table 1 The capture and recovery device of carbon dioxide in flue gas treats CO in the flue gas of a coal-fired power plant 2 material balance sheet

[0068]

[0069] It can be seen from Table 1 that when the flue gas flow rate of a certain power plant after dedusting and desulfurization is 10000Nm 3 / h, CO 2 When the content is 12.37%, the permeate gas (product gas) flow rate of the second stage membrane separation unit obtained by the membrane separation process in this embodiment is 699Nm 3 / h, CO 2 The content is 97.11%.

[0070] For high-pressure energy recovery, Table 2 shows the recovery of CO2 in the flue gas of a coal-fired power plant using a turbo expander to re...

Description

technical field [0001] The invention relates to the technical field of gas recovery, in particular to a device and method for capturing and recovering carbon dioxide in flue gas. Background technique [0002] Global warming is one of the major environmental problems in the world at present. Among the various greenhouse gases that cause climate change, CO 2 The biggest impact on global warming, control CO 2 Emission has become one of the important technical routes to deal with climate warming. CO produced by human activities 2 The largest part of emissions comes from coal-fired power generation, and the CO in the combustion tail gas of coal-fired power plants 2 The emission has the characteristics of low concentration, stability, concentration and large volume, and is a large-scale CO emission reduction 2 one of the best fields. [0003] high purity CO 2 It is an important industrial gas, and the separated and captured CO 2 Not only can it be injected into oil and natu...
