Abstract

Se pretende proporcionar un método capaz de reducir la concentración de ácido fórmico en el ácido acético del producto mediante un enfoque sencillo; el método para producir ácido acético de acuerdo con la presente comprende al menos una etapa seleccionada de una etapa que satisface las siguientes condiciones de operación (i) y una etapa que satisface las siguientes condiciones de operación (ii) en un proceso de producción de ácido acético: (i) condiciones de operación que impliquen una presión parcial de hidrógeno inferior a 500 kPa (presión absoluta), una presión parcial de dióxido de carbono inferior a 70 kPa (presión absoluta) y una temperatura de operación superior a 175ºC; y (ii) condiciones operación que impliquen una presión parcial de hidrógeno no mayor a 5 kPa (presión absoluta), una presión parcial de dióxido de carbono inferior a 20 kPa (presión absoluta), y una temperatura de funcionamiento superior a 100ºC.It is intended to provide a method capable of reducing the concentration of formic acid in the acetic acid of the product by a simple approach; The method for producing acetic acid according to the present invention comprises at least one stage selected from a stage that satisfies the following operating conditions (i) and a stage that satisfies the following operating conditions (ii) in an acid production process acetic: (i) operating conditions that involve a partial pressure of hydrogen below 500 kPa (absolute pressure), a partial pressure of carbon dioxide below 70 kPa (absolute pressure) and an operating temperature above 175ºC; and (ii) operating conditions that involve a partial pressure of hydrogen not exceeding 5 kPa (absolute pressure), a partial pressure of carbon dioxide less than 20 kPa (absolute pressure), and an operating temperature exceeding 100 ° C.
