Description

Technical Field

[0001] The present invention relates to the field of carbon dioxide capture, and in particular to a drying system. Background Art

[0002] Carbon dioxide capture technology is one of the key technologies to address global climate change. However, existing drying systems have some limitations in design and operation. Typically, these drying systems rely on a single drying tower to process the gas emitted from industrial sources to remove moisture and other contaminants to obtain high-purity carbon dioxide. Although this single drying tower design can meet basic needs in some cases, it has a bottleneck in processing capacity.

[0003] When faced with large-scale emission sources, the processing capacity of a single drying tower is insufficient to cope with high gas flows. This causes the drying system to take longer to process the same amount of gas, thereby reducing the overall processing efficiency. Secondly, since the working principle of the drying tower is usually to remove moisture through adsorption or chemical reaction, the design of a single tower will experience performance degradation during continuous operation, requiring regular maintenance and replacement of adsorbents, which increases operating costs.
