Abstract

PROCESSO PARA PRODUçãO DE áCIDO (MET) ACRìLICO OU (MET) ACROLEìNA Um processo para produção de ácido (met) acrílico ou (met) acroleína compreendendo submeter pelo menos uma matéria-prima, selecionada de entre propileno, propano, isobutileno e (met) acroleína, a uma reação de oxidação por contato com fase vapor com oxigênio molecular ou um gás contendo oxigênio molecular, para assim obter ácido (met) acrílico ou (met) acroleína, no qual a matéria-prima é misturada com o oxigênio molecular ou gás contendo oxigênio molecular, de antemão, e o gás resultante é guiado com segurança para o reator, enquanto eliminando a geração e a propagação de chama, realizando-se desse modo uma operação segura. Proporciona-se um processo para produção de ácido (met) acrílico ou (met) acroleína, caracterizado pelo fato de que um gás misto, resultante da mistura da matéria-prima com o oxigênio molecular ou gás contendo oxigênio molecular, é alimentado por meio de uma tubulação equipada com um impedidor de propagação de chama ao reator.
