Abstract

<B>PROCESSO PARA REMOçãO DE SULFETO DE HIDROGêNIO<D> O sulfeto de hidrogênio é removido de correntes gasosas pela reação com dióxido de enxofre para produzir enxofre. A reação é efetuada em um meio de reação que compreende uma base de Lewis não-aquosa com um valor de pK~ b~ de cerca de 6 a cerca de 11. O meio de reação processa uma combinação específica de propriedades; a) absorve dióxido de enxofre e reage quimicamente com o mesmo para formar um produto de reação; b) absorve sulfeto de hidrogênio; c) remove o sulfeto de hidrogênio da corrente gasosa através do contato da corrente gasosa com o meio de reação, em presença de dióxido de enxofre livre e/ou o produto de reação; d) atua como um catalisador para a reação total do sulfeto de hidrogênio com o dióxido de enxofre para produzir enxofre, e e) possui a capacidade de absorver dióxido de enxofre em quantidade suficiente para remover, substancialmente, todo o sulfeto de hidrogênio da corrente gasosa, apesar de variações de curto prazo no equilíbrio estequiométrico entre o sulfeto de hidrogênio e o dióxido de enxofre no meio de reação.
