Abstract
"MéTODO DE TRATAMENTO DE UM SISTEMA AQUOSO CONTENDO OU EM CONTATO COM INCRUSTAçãO DE SULFETO DE METAL, MISTURA SINéRGICA, FORMULAçãO, E, USO DA MISTURA SINéRGICA". A presente invenção refere-se a um método de tratamento de um sistema aquoso contendo ou em contato com incrustação de sulfeto de metal. O método compreende adicionar no citado sistema, separada ou juntamente, o suficiente de uma mistura sinérgica compreendendo sal de THP¬ +¬ uma solução aquosa de um ácido forte (e opcionalmente uma fonte de nitrogênio) para proporcionar uma solução contendo de 0,1% a 30% em peso de sal de THP¬ +¬ em um pH menor do que cerca de 1,0. A incrustação é contatada corn a citada solução, (dissolvendo deste modo pelo menos parte da citada incrustação na citada solução) e a incrustação dissolvida é removida do sistema.
