N2 - This article is part II of the series of two papers
regarding the application of oxygen blast furnace (OBF)
in Ruukki Metals Ltd.’s existing steel mill, located in
city of Raahe, Finland. The economic assessment presented
in this paper is based on the technical modelling
presented in part I of the study. OBF with CCS would lead
to large reductions in CO2 emissions but also OBF without
CCS would decrease emissions significantly due to
decreased coke consumption. From economic point of view,
other important consequences of OBF process are increased
LPG or LNG (liquefied petroleum gas or liquefied natural
gas) consumption, decreased electricity production
(increased purchase from markets), required investments
and CO2 transportation and storage costs. As CCS
processes typically, especially application of OBF is a
trade-off between decreased electricity production and
decreased emissions. Therefore a correlation between CO2
price development and electricity price development is of
interest. In this paper, several sensitivity analyses are
presented with different prices for CO2, electricity and
other parameters. The results present the sensitivity of
different options in terms of economic feasibility for
large CO2 reductions in the integrated steel mill based
on blast furnace process.
