“…According to Nernst formula [31], the liquid phase diffusion rate is (35) where and are the electrical conductivities of cation and anion, respectively; and are the absolutes of positive and negative ion valency, respectively. (3) Mass transfer coefficient The mass transfer flux is written as (36) where K x and K y are the overall mass transfer coefficients based on liquid or gas phase, respectively [kmol/(m 2 •s)]; K is the overall mass transfer coefficients of the whole system, [kmol/(m 2 •s)]; x and y are the HCl fractions in the liquid phase and gaseous phase before the mass transfer, respectively; x e is the molar fraction of liquid phase which is in phase equilibrium with y; and y e is the molar fraction of gaseous phase which is in phase equilibrium with x. The coefficients satisfy the following relations [32]:…”

With the broad application of dry dedusting of blast furnace gas (BFG), the issue of BFG pipeline corrosion comes up because of chlorine in the BFG. Existing methods in preventing the corrosion, such as spraying alkali or installing corrosion-resistant materials, require a significant amount of investment. This paper conducted a novel thermal analysis of the corrosion mechanism to support the study on corrosion prevention without using additional materials. Firstly, thermal models were established to reflect the relationships among the amount of condensation water, the mass transfer rate, the concentration of chloride ion and the ambient temperature. Secondly, the relationship between BFG temperature and the corrosion rate was obtained via a cyclic exposure experiment. Key factors that affect the pipeline corrosion under various BFG temperatures were identified. Finally, a control scheme of the BFG temperature was proposed to avoid the chlorine corrosion.
