Since the “Davy Cone” was developed in the 1980s, Primetals Technologies has had a 40-year period of development and application of its gas cleaning solutions. This paper will introduce the single-cone wet scrubber solutions originally designed for the British Steel Scunthorpe UK blast furnaces (the “four Queens”) and the modifications made to existing infrastructure to incorporate the Davy Cone scrubbers. The paper will then discuss the triple-cone solutions, the problems caused by acid gases, and the solutions trialed and implemented, as well as the development of the Tri-Ax cyclone and the MERIM dry cleaning solution.
