Abstract
"PROCESSO CONTìNUO PARA A SEPARAçãO DE UMA FRAçãO C~ 4~ POR DESTILAçãO EXTRATITVA COM UM SOLVENTE SELETIVO EM UMA COLUNA DE DESTILAçãO EXTRATIVA". A invenção refere-se a um processo contínuo para a separação de uma fração C~ 4~ (C~ 4~) por destilação extrativa que usa um solvente seletivo (LM) em uma coluna de destilação extrativa (EDK). Uma parede divisória (TW) que forma uma primeira região parcial (A), uma segunda região parcial (B) e uma região da coluna combinada inferior (C). está disposta na direção longitudinal na coluna de destilação extrativa (EDK). De acordo com este processo, uma corrente de topo (C~ 4~H~ 10~) que compreende o butano é separado da primeira região parcial (A), uma corrente de topo (C~ 4~H~ 8~) que compreende o buteno é separada da segunda região parcial (B) e uma corrente (C~ 4~H~ 6~) que compreende os hidrocarbonetos da fração C~ 4~ é separado da região da coluna combinada inferior (C), os ditos hidrocarbonetos dissolvendo-se mais facilmente no solvente seletivo (LM) do que o butano e o buteno.
