Abstract

"MéTODO DE INIBIçãO DA CORROSãO DE EQUIPAMENTO METáLICO QUE E LIMPO COM UM áCIDO INORGâNICO". A corrosão de um equipamento metálico que é limpo com um ácido inorgânico é inibida pelo tratamento do equipamento com uma composição inibidora de corrosão contendo pelo menos um composto de amónio quaternário, um composto contendo enxofre e um tensoativo não-iónico em um solvente.
