Abstract

"PROCESSO PARA A PRODUçãO DE áGUA PURIFICADA A PARTIR DA áGUA DA REAçãO DE FISCHER-TROPSCH". Um processo para a produção de água altamente purificada (38) a partir da água de reação de Fischer-Tropsch (12) inclui pelo menos os estágios de um estágio de tratamento primário, que compreende um processo de separação em estágio de equilíbrio (14) tendo pelo menos um estágio para a remoção de pelo menos uma fração de hidrocarbonetos oxigenados não ácidos a partir da água da reação de Fischer-Tropsch (12) para produzir uma corrente primária enriquecida em água (16), um estágio de tratamento secundário compreendendo pelo menos um processo de separação por membrana (28) para a remoção de pelo menos alguns sólidos suspensos e hidrocarbonetos ácidos oxigenados a partir de pelo menos uma porção da corrente enriquecida em água (16) para produzir uma corrente secundária enriquecida em água (34) e um estágio de tratamento terciário, que compreende um estágio de remoção de orgânicos e de sal dissolvido (36) para remover pelo menos alguns dos sais dissolvidos e constituintes orgânicos a partir de pelo menos uma porção da corrente secundária enriquecida em água (34).
