Methods for inhibiting pyrophoric iron sulfide activity are disclosed. Methods are disclosed for inhibiting the sulfidation of iron oxides to iron sulfides and/or the oxidation of iron sulfide to inhibit pyrophoric activity. The methods comprise contacting iron oxides and/or iron sulfide with a liquid, solution, aerosol, or gaseous inhibitor comprising alkylamines, arylamines, imines; oxygen-containing compounds such as alcohols, aldehydes, esters, acids and ketones; mixed nitrogen-containing and oxygen-containing compounds such as alkanolamines, non-polymeric amides, hydroxylamines, Mannich products, polyisobutylenesuccinimides, oximes; sulfur-containing compounds and phosphorus-containing compounds.

Los métodos para inhibir actividad pyrophoric del sulfuro del hierro se divulgan. Los métodos se divulgan para inhibir el sulfidation de los óxidos del hierro para planchar los sulfuros y/o la oxidación del sulfuro del hierro para inhibir actividad pyrophoric. Los métodos abarcan entrar en contacto con los óxidos del hierro y/o el sulfuro del hierro con un líquido, una solución, un aerosol, o un inhibidor gaseoso que abarca los alkylamines, arylamines, iminas; oxi'geno-contener compuestos tales como alcoholes, aldehinos, ésteres, ácidos y cetonas; compuestos nitrogen-containing y oxi'geno-que contienen mezclados tales como alkanolamines, amidas no-polime'ricas, hidroxilaminas, productos de Mannich, polyisobutylenesuccinimides, oximes; compuestos con sulfuro y compuestos con fósforo.
