The customer Steel industry plants all over the world have multiple processes, most of them emitting CO and CO2 in very high concentrations (tens of %). CO is used as a combustible due to its high calorific value. It is stored in a huge tank before it is used by the power plant next door. CO in such high concentration is explosive in presence of a few molecules of oxygen. Therefore, ...
