Abstract

"PROCESSO E APARELHO PARA EXTRAIR UM COMPONENTE DE LìQUIDOS" Um processo para extração de um componente de líquidos usando fluidos supercríticos ou gases de fase densa (solvente de fase densa). O processo contacta um líquido e o solvente de fase densa em um misturador rotativo para dissolver uma fração desejada para dentro do solvente de fase densa a fim de formar um solvente carregado. Em adição, o misturador separa o solvente carregado do rafinado remanescente. Então o misturador rotativo descarrega o solvente carregado e o rafinado. Pressão decrescente sobre o solvente carregado converte o solvente carregado em um gás e a fração desejada para liberar a fração desejada do gás.
