Abstract
"PROCESSO PARA O TRATAMENTO DE CONDENSADOS QUE CONTêM COMPOSTOS". A presente invenção refere-se a um processo de tratamento de condensados que contêm compostos, os quais são mais voláteis do que a água, em uma instalação de evaporação, onde líquido, tal como líquido efluente proveniente de uma fábrica de polpa ou papel é evaporado em diversos estágios e onde os condensados gerados na evaporação são vaporizados e purificados em uma coluna de separação de vapor. No processo, os condensados provenientes de pelo menos dois estágios de evaporação são combinados e vaporizados em conjunto, e o vapor obtido a partir da vaporização é levado ao contacto com uma corrente de condensado para ser purificado na coluna de separação, de onde são descarregados o vapor que contém impurezas e a corrente de condensado purificado.
