Abstract

Procedimiento para la preparación en contínuo de soluciones acuosas de formaldehído, en el que se utiliza una columna de alimentación y unosintercambiadores adicionales de calor relacionados con unas columnas de absorción; en la columnade alimentación entra aire y metanol procedentes delexterior, asi como una subcorriente de metanol, originada de una corriente de metanol frío que sale de la columna de alimentación; esta corriente de salidarecircula por los intercambiadores adicionales de calor y se divide en la subcorriente que retorna a la columna de alimentación y en otra subcorrienteque alcanza un evaporador; de la cabeza de la columna de alimentación, sale una mezcla metanol y aire, que alcanza un evaporador. El metanol frío se enfría enel interior de la columna de alimentación, por la evaporación del metanol que forma parte de la mezcla de metanol y aire.
