Abstract

PROCESSO PARA RECUPERAÇçO DE METANOL. A presente invenção refere-se a um método para recuperação do metanol das misturas contendo o metanol e água. O dito método compreende a evaporação em múltiplos estágios com a integração do calor, a pressão sendo diminuída de um estágio para o seguinte, seguido por uma série de estágios de destilação com a integração do calor, a pressão sendo aumentada de um estágio para o seguinte, O método de acordo com a presente invenção permite que a quantidade de energia necessária para recuperação do metanol seja reduzida.
