Abstract

El proceso para refinar etilenglicol crudo de base biológica incluye el uso de etilenglicol crudo de base biológica como materia prima, diluir con agua a una concentración de etilenglicol de 1 a 95% en peso, estando la solución acuosa de etilenglicol diluida a una temperatura de 0-100 °C, bajo la condición de una velocidad espacial volumétrica de 0,01-20 BV/hora, obtiene después del tratamiento de adsorción la solución acuosa de etilenglicol purificada pasando continuamente a través de un lecho de adsorción lleno con una o más resinas de adsorción macroporosas y opcionalmente resinas de intercambio iónico, y luego obtener etilenglicol después de la deshidratación
