1. recycle a method for gas fired-boiler flue gas, it is characterized in that, comprise the following steps:

  • S1, reduces the exhaust gas temperature of gas fired-boiler flue gas, makes the water vapor condensation in described flue gas, with the content utilizing condensed water to reduce the pernicious gas in described flue gas;

    Wherein, described gas fired-boiler flue gas is specifically by the flue gas produced during refinery crude oil;

    S2, sends the described flue gas after condensation cooling into CO 2capturing device, to the CO in described flue gas 2trap;

    S3, sends into desulfuring and denitrifying apparatus, to remove remaining SO in described flue gas by the described flue gas after trapping xwith NO remaining in described flue gas x;

    S4, to the N in the described flue gas after desulphurization denitration process 2reclaim;

    S5, respectively to the CO of trapping 2with the N reclaimed 2liquefy;

    S6, respectively by the CO of liquid state 2with the N of liquid state 2inject well recovery, to obtain described crude oil, used for oil refining.
