METHOD TO CONVERT END GAS PRODUCED IN METALLURGICAL FURNACE, METHOD TO PRODUCE CONVERTED GAS, DEVICE FOR REFORMING OF END GAS, DEVICE TO CONVERT END GAS, METHOD TO COOL END GAS AND DEVICE TO COOL END GAS Russian patent published in 2012 - IPC C21C5/38 

FIELD: oil and gas production.

SUBSTANCE: method is realised by addition of a recovery agent into end gas, containing a high-temperature gaseous carbon dioxide, leaving the metallurgical furnace, in order to provide interaction of gaseous carbon dioxide with a recovery agent to convert end gas. The recovery agent is added, when oxygen concentration in end gas is 1 vol.% or below. The process of end gas conversion is completed, when temperature of end gas makes 800°C or higher. To implement this method, two versions of the device are used.

EFFECT: reduced emissions of gaseous carbon dioxide together with higher heat content of end gas.
