Abstract

BONO DE UM GáS DE PROCESSO". A invenção refere-se à absorção de dióxido de carbono de um gás de procrnecer bicarbonato de potássio, na presença de dietanolamina como um catalisador e um vanadato de poessorção do dióxido de carbono do circuito. Os sais ácidos orgânicos de potássio acumulam-se no circuito e há uma retirada de uma corrente secundária de parte da solução aquosa do circuito, sua diluição com diluente aquoso e sua passagem em uma membrana semi-permeável, para remover os sais ácidos orgânicos de potássio da corrente secundária, como uma sua solução aquosa. Os ânions de vanadato são impedidos de passar através da membrana e o resto da corrente secundária é retornada para o circuito, composição de carbonato de potássio e dietanolamina sendo adicionada ao circuito, quando necessário.
