Abstract

Patente de Invenção:<B>"PROCESSO DE SEPARAçãO DE UMA CARGA C5-C8 OU DE UMA CARGA INTERMEDIáRIAS, EM TRêS EFLUENTES RESPECTIVAMENTE RICOS EM PARAFINAS LINEARES, MONORRAMIFICADAS E MULTIRRAMIFICADAS"<D>. Descreve-se um processo de separação que permite obter três efluentes respectivamente ricos em parafinas lineares, em parafinas monorramificadas e em parafinas dirramificadas, trirramificadas e eventualmente em compostos naftênicos e/ou aromáticos, a partir de cortes C5-C8 ou de cortes intermediários (C5-C7, C6-C8, C7-C8, C6-C7, C7 ou C8) que compreendem hidrocarbonetos parafínicos e eventualmente naftênicos, aromáticos e olefínicos. Esse processo de separação emprega pelo menos duas unidades de separação que funcionam seja por adsorção seja por mermeação. O processo da invenção é especialmente útil quando ele á acopaldo com um processo de hidro-isomerização pelo fato de que ele permite uma reciclagem seletiva das parafinas lineares e monorramificadas, necessária para as parafinas que possuem pelo menos 7 átomos de carbono.
