1000 kg of liquid steel containing 0.03 wt.% S needs to be desulphurized using a slag to bring the sulphur content down to 0.015 wt.%. The quantity of slag needed is _______ kg (round off to the nearest integer).
Assume:
1. Thermodynamic equilibrium
2. No sulphur in the slag prior to desulphurization treatment Given the equilibrium sulphur partition ratio between slag and steel,
((wt.%S)in slag) / ([wt.%S]in steel) is 50.
