Abstract

"LIQUEFAçãO DE GáS NATURAL". A presente invenção refere-se a um processo para liquefação de gás natural (50) em conjunto com a produção de uma corrente de líquido contendo, predominantemente, hidrocarbonetos mais pesados do que metano (41). No processo, a corrente de gás natural a ser liquefeita (31) é parcialmente resfriada, expandida até uma pressão intermediária (14, 15) e fornecida a uma coluna de destilação (19). O produto de fundo (41) dessa coluna de destilação, de preferência, contém a maior parte de quaisquer hidrocarbonetos mais pesados do que metano, o que, de outro modo, reduziria a pureza do gás natural liquefeito (50). A corrente de gás residual (37) da coluna de destilação (19) é comprimida (16) até uma pressão intermediária maior, resfriada sob pressão (60) para condensá-la e, a seguir, expandida (61) em baixa pressão, para formar a corrente de gás natural liquefeito.
