Abstract

Blast furnace gas is a secondary product of cast-iron smelting. Nowadays, many metallurgy companies in Russia and Europe use blast furnace gas scrubbing systems designed by the Luxembourg-based company Paul Wurth. Speaking of the efficiency and energy cost of purifying blast-furnace gas by such scrubbing system, the heat-and-mass transfer in the pre-scrubber is of utmost importance. The paper presents computational analysis of pre-scrubber heat-and-mass transfer for different dispersed processed water drop sizes. Computations are based on heat balance equations for droplets of dispersed process water flowing in the stream of impure blast-furnace gas. The analogy of heat energy and mass transfer processes is used for computing the heat and mass loss factors.
