The results show that most of the inclusions can be removed after treatment for 12 min, and all the inclusions which can be removed almost disappeared from the system after treatment for 24 min. Larger lift gas flow rates seemed to be more efficient for inclusions removal and there is a lift gas flow rate for the best of inclusions removal (20 L/min for this work). The liquid height in vacuum vessel has also an optimized value for inclusions removal (46 mm for this work).
