CO2 For pH Control To Prevent Scaling In The BOF/BF Scrubber Water Circuit In Steel Mills

The Blast Furnace (BF) is a critical process unit in the iron and steel industry, which converts iron ore into molten iron and is the beginning of the process in the manufacturing of steel. The Basic Oxygen Furnace (BOF) is a vessel that is used to reduce carbon in liquid iron from ~4%, down to 0.04%. The combustion of carbon in the BOF is enabled by blowing pure O2 into the melt.
