CARRILLO, F.; HERNANDEZ, R.; MARTINEZ, J.  y  ROSELLO, A.. Kinetics of the Copper Blow in the Peirce-Smith Converter. Inf. tecnol. [online]. 2004, vol.15, n.5, pp. 33-36. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642004000500005.

A model is established for the behaviour of the Peirce-Smith converter during the copper blow using a kinetic treatment. A study was carried out with a laboratory reactor to then apply scaling techniques for its application to an industrial reactor. The desulfurisation rate of copper sulfide was obtained in a laboratory bubbling reactor as a function of temperature and gas flow. It was found that the conversion of sulfur was independent of temperature, but was highly influenced by the flow. Scaling-up was carried out assuming the same overall volumetric coefficient for both laboratory and commercial scales. A fair agreement between model and experimental data of the industrial reactor was found when sulfur conversion was below 90%

Palabras clave : desulfurization kinetics; oxidation of copper sulfide; scaling-up; Peirce-Smith converter.
