ABSTRACT: The main
components of the operational costs structure of the Kanbara Reactor, Magnesium
Mono-Injection and Co-Injection desulphurization processes for hot metal are
discussed here. The pros and cons of lime, magnesium and calcium carbide as
desulphurization agents are discussed, too. The
aim of this work is to compare the updated operational costs reported in the
literature in the last decade among the above processes using the accumulated
annual inflation rates of US dollar, euro and Indian rupees. Besides, the
operational costs of the process are discussed in terms of the initial and
final sulphur content and the degree of desulphurization. The KR process
presents the lowest reagents costs, whereas the co-injection process presents
the highest reagents costs. The KR process presents the highest iron and
temperature losses given the great amount of slag generated and the intense
agitation of the rotary impeller. The co-injection process presents an
exponential growth of the desulphurization costs as higher desulphurization
degree is required.
