Abstract
PROCESSO PARA PRODUZIR BIODIESEL DE GLICERìDEOS E PROCESSO PARA PRODUçãO DE BIODIESEL PURIFICADO DE GLICERìDEOS. Um sistema e método para conversão de ácidos graxos livres em glicerídeos e a subseqúente conversão de glicerídeos em glicerina e biodiesel inclui a transesterificação de uma corrente de glicerídeo com um álcool. Os ésteres de alquila de ácido graxo são separados da glicerina para produzir uma primeira fase líquida contendo uma corrente (concentrada> rica em éster de alquila de ácido graxo e uma segunda fase líquida contendo uma corrente (concentrada) rica em glicerina. A corrente rica em éster de alquila de ácido graxo é então submetida a destilação, preferivelmente destilação reativa, segundo a qual a corrente se submete ambas a separação física e reação química. A corrente rica em éster de alquila de ácido graxo é então purificada para produzir um produto de biodiesel purificado e uma corrente residual rica em glicerídeo. Biodiesel pode ser ainda recuperado da corrente residual rica em glicerídeo, por posterior separação de e/ou processamento de glicerídeos/ácidos graxos livres contidos no mesmo. A corrente da segunda fase líquida rica em glicerina pode ainda ser purificada para produzir um produto de glicerina purificada e uma (segunda) corrente de álcool úmido. Neutralização da corrente alcalina, formada durante o processo da transesterificação catalisada por ácali, pode proceder pela adição de um ácido mineral ou um orgânico.
