NR= (H2+СО)/(Н2О+СО2),
где под Н2, СО, Н2О и СО2 подразумевают процентное объемное содержание этих компонентов в частично отработанном газообразном раскислителе и подвергнутом реформингу газообразном раскислителе.2. The method according to claim 1, wherein the deoxidizing capacity (N R ) of the partially spent gaseous deoxidizing agent is 4.5 and in which the deoxidizing capacity of the gaseous deoxidizing agent subjected to reforming is 6.2, and the deoxidizing ability is determined as follows
N R = (H 2 + CO) / (H 2 O + CO 2 ),
where H 2 , CO, H 2 O and CO 2 mean the percentage volume content of these components in the partially spent gaseous deoxidizer and the gaseous deoxidizer subjected to reforming.
Nох= (CO2+H2O)/(CO+CO2+H2+H2O),
где под СО, СО2, Н2 и Н2О подразумевают процентное объемное содержание этих компонентов в смеси.13. The method according to p. 1, in which the stage of mixing includes mixing the oxygen source with a partially exhaust gaseous deoxidizer in such a way as to obtain a mixture, which is characterized by the value of the reforming ratio (CH 4 / N oh ) ranging from about 57 to 72, where CH 4 indicates the volume percentage of methane, and the value of N ooh is determined as follows
N oh = (CO 2 + H 2 O) / (CO + CO 2 + H 2 + H 2 O),
where CO, CO 2 , H 2 and H 2 O mean the percentage by volume of these components in the mixture.
