Abstract

Patente de Invenção:<B>"PRé-ENRIQUECIMENTO ELETROLìTICO PARA A ELETRóLISE COMBINADA E PROCESSO DE TROCA CATALìTICA"<D>. Um pré-enriquecimento eletrolítico de uma corrente de alimento para um processo de eletrólise combinada e produção de água pesada de troca catalítica ("CECE"). Um líquido enriquecido com deutério ou corrente de vapor a partir das células eletrolíticas é aplicado com um alimenta do primeiro estágio de um processo de enriquecimento de deutério CECE. Pela disposição de uma porção da capacidade de célula eletrolítica disponível no estágio de pré-enriquecimento, vantagens são obtidas, particularmente onde a energia elétrica disponível flutua ou quando um processo CECE "desligado" é desejado.
