(PT) método de tratamento de gás e dispositivo de tratamento de gás
要約
(PT) método de tratamento de gás e dispositivo de tratamento de gás. um aspecto da presente invenção é um método de tratamento de gás, incluindo: uma etapa de absorção para colocar um gás a ser tratado, que contém dióxido de carbono e um composto de enxofre, em contato com um líquido de absorção a ser separado por fases pela absorção de dióxido de carbono, para fazer com que o líquido de absorção absorva o dióxido de carbono e o composto de enxofre; e uma primeira etapa de liberação de aquecimento do líquido de absorção colocado em contato com o gás a ser tratado a uma temperatura igual ou superior a uma temperatura na qual o dióxido de carbono absorvido pelo líquido de absorção é liberado do líquido de absorção e inferior a uma temperatura em que o composto de enxofre absorvido pelo líquido de absorção é liberado do líquido de absorção, para liberar o dióxido de carbono do líquido de absorção.
