Abstract

"PROCESSO E APARELHO PARA REFINO DE BIODIESEL". Processo e aparelho para produção de combustível biodiesel, isto é, éster alquílico, a partir de óleo vegetal e/ou animal. um catalisador de transesterificação é preparado em um tanque de catalisador básico por pulverização de álcool alquílico sob pressão através de jatos em pelotas de hidróxido metálico, até que as pelotas tenham reagido completamente com o álcool. O óleo é aquecido e transesterificado na presença de álcool alquílico e catalisador de transesterificação em um sistema de fluxo de transesterificação com recirculação fechado, sob leve cavitação, para fornecer um produto de éster alquílico e um produto de glicerol. A cavitação é conseguida permitindo-se que o ar entre no sistema de fluxo de transesterificação através de uma válvula de entrada de ar ajustável. Quando deixado em repouso, o produto de éster alquílico forma uma camada superior que é decantada e submetida a etapas de purificação para remover partículas e álcool alquílico do produto de éster alquílico, e uma camada inferior de produto de glicerol, que é drenada. A purificação do produto de éster alquílico inclui, de preferência, a submissão do produto de éster alquílico a uma névoa de água aplicada por cima em um tanque de lavagem, com infusão simultânea de uma corrente de bolhas de ar. O vapor de álcool é reciclado como álcool líquido dentro de um condensador de álcool e armazenado para reutilização. Se o óleo contiver ácidos graxos livres, antes da transesterificação, o óleo é aquecido, e os ácidos graxos livres são esterificados na presença de um catalisador de esterificação e álcool alquílico. Por razões de segurança, instalam-se anteparos e barreiras amortecedoras de explosão/corta-fogo em locais em que vapores inflamáveis representem um risco.
