Abstract
"PROCESSO PARA REMOVER H~ 2~S". Para tratar correntes de gases não-condensáveis contendo H~ 2~S, e para tratar vapor contendo H~ 2~S, o processo sendo definido por uma divisão inédita do vapor não-condensável, ou de uma corrente contendo H~ 2~S não-condensável separada derivada do vapor, com tratamentos diferentes das porções separadas. A invenção é particularmente adequada para tratar o vapor de escape de uma turbina a vapor que utiliza vapor geotérmico como fluido de trabalho. Em um aspecto preferido, o descarte do enxofre produzido como um subproduto normal de etapas oxidativas líquidas pode ser reduzido ou até totalmente evitado através de reação do enxofre com bissulfito e/ou sulfito produzido no procedimento para produzir tiossulfato solúvel.
