Abstract

A process for producing an aromatic carboxylic acid which comprises an oxidation step and a step in which a discharge gas generated in the oxidation step is burned, wherein the discharge gas, which contains methyl bromide, is burned while inhibiting the generation of a brominated dioxin. Specifically, the process for aromatic-carboxylic-acid production comprises: an oxidation step in which an alkylaromatic compound is oxidized in the presence of a bromine compound to obtain an aromatic carboxylic acid; and a step in which a discharge gas generated in the oxidation step is burned in a burner. In the process, the discharge gas is burned at a combustion temperature of 450-1,000°C and the gas resulting from the combustion is cooled to 250°C or lower. In the cooling step, the time required for cooling from 450°C to 250°C is 1 second or shorter.
