Abstract

<B>MéTODO DE DESTILAçãO E APARELHO DE DESTILAçãO"<D>. Em um método para destilar ácido (met)acrílico e/ou éster (met)acrílico, o método tem a etapa de distribuir uniformemente um líquido de fornecimento em uma torre de destilação sobre a totalidade de uma área em seção transversal horizontal na torre de destilação. Um aparelho de destilação para destilar ácido (met)acrílico e/ou éster (met)acrílico em uma torre de destilação tem meio de fornecimento para fornecer o líquido de fornecimento à torre de destilação. O meio de fornecimento é formado com pelo menos dois orifícios de fornecimento através dos quais o líquido é fornecido à torre de destilação.
