摘要： The present disclosure provides a method and a system for denitrogenation combustion and CO2 capture and utilization in a gas boiler. The method is implemented by the system for denitrogenation combustion and CO2 capture and utilization in the gas boiler, and comprises: after circulating flue gas is discharged from a gas boiler, introducing the circulating flue gas into a gas heat exchanger to perform heat exchange with natural gas, hydrogen, and carbon-based denitrogenation gas; introducing the circulating flue gas after heat exchange into a flue gas dehydration device to perform dehydration; introducing a first portion of the circulating flue gas after the heat exchange and dehydration into a blower through the flue gas dehydration device to be pressurized by the blower and introduced into a carbon-based denitrogenation gas mixer; preparing the carbon-based denitrogenation gas by mixing oxygen and the circulating flue gas using the carbon-based denitrogenation gas mixer for combustion for the gas boiler; and introducing a second portion of the circulating flue gas after heat exchange and dehydration into a CO2 recovery device to perform purification and deoxygenation through the flue gas dehydration device to obtain a CO2 product, and pressurizing and transmitting the CO2 product to a CO2 utilization device through a CO2 compressor.

摘要： The embodiments of the present disclosure provide a full recovery process for carbon dioxide emitted from a catalytic cracking regeneration device, which is executed by a processor of a full recovery system for carbon dioxide. The full recovery process includes recovering, through a flue gas recovery device, a circulated flue gas generated by the catalytic cracking regeneration device, and mixing the circulated flue gas and oxygen to produce a carbon-based gas; determining a concentration sequence and a gas flow rate sequence in a connection pipe, and a reaction parameter of the catalytic cracking regeneration device; determining a combustion feature based on the concentration sequence and the gas flow rate sequence; and in response to the combustion feature satisfying a first preset condition, determining a target opening combination of a target flow rate regulating valve based on at least the combustion feature and the reaction parameter.
